JIT miscompilation in Firefox's SpiderMonkey JavaScript engine exposes sensitive memory to remote attackers via crafted web content. The CWE-843 (type confusion) root cause means the JIT compiler generates native code that accesses a JavaScript value as the wrong type, resulting in a high-confidentiality information disclosure. Vendor-released patches are available in Firefox 154, Firefox ESR 140.14, and Firefox ESR 153.1; no public exploit or CISA KEV listing has been identified at time of analysis.
Race condition and use-after-free memory corruption in Mozilla Firefox's Graphics component allows remote unauthenticated attackers to achieve limited confidentiality and integrity impact when a user visits a malicious web page. Affected across the standard release channel and all ESR branches, the vulnerability is fixed in Firefox 154, ESR 115.39, ESR 140.14, and ESR 153.1 per Mozilla's official advisories. No public exploit code has been identified and CISA has not listed this in KEV; the SSVC framework rates exploitation status as none and marks it not automatable.
Unexpected process termination in Apple iOS/iPadOS and macOS Tahoe can be triggered remotely by luring a user to visit maliciously crafted web content, exploiting a use-after-free flaw in the web content rendering engine. The vulnerability affects iOS and iPadOS versions prior to 26.6.1 and macOS Tahoe prior to 26.6.2, with impact limited to availability - crashing the affected browser or WebKit-based process - and no confirmed confidentiality or integrity loss. No public exploit code or CISA KEV listing is identified at time of analysis, though the low-complexity, network-accessible attack surface warrants prompt patching given the broad Apple device install base.
Use-after-free memory corruption in Apple's WebKit web rendering engine crashes the browser process when handling maliciously crafted web content on iOS, iPadOS, and macOS Tahoe. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) confirms network-reachable exploitation limited to availability impact - a process crash - with no confidentiality or integrity compromise. Apple has released fixes across both the legacy iOS 18.x branch and the current iOS 26.x line, indicating broad exposure across the installed base. No active exploitation or public proof-of-concept has been identified at time of analysis.
Out-of-bounds stack read and write in the WNC-M14A2A LTE-M modem driver (wncm14a2a.c) within Zephyr RTOS versions 1.13.0 through below 4.4.2 allows a rogue cellular base station or RF attacker to crash the modem RX thread and leak adjacent stack memory without any application interaction. The defect fires automatically on receipt of an unsolicited %NOTIFYEV: event whose payload exceeds 39 bytes and lacks a quote character within the linearized region, causing scanning loop indices to walk past the fixed 40-byte stack buffer. While the write primitive is weakly controlled — limiting demonstrated impact to denial of service and stack disclosure — the CVE is tagged RCE by reporters, though the description explicitly states memory-safe code execution has not been demonstrated. No public exploit or CISA KEV listing exists at time of analysis.
Use-after-free in HarmonyOS 6.1.0's time and time zone module allows a local low-privileged attacker to crash the affected component, degrading availability. Exploitation is local and requires existing user-level access, limiting the realistic attacker pool to on-device processes or malicious apps. No public exploit code or active exploitation has been identified at time of analysis.
Memory corruption and denial of service in Zephyr RTOS's second-generation delayable work queue (kernel/work.c) arise because the documented safe-cancellation APIs-k_work_cancel_delayable_sync() and k_work_flush_delayable()-fail to block until an in-flight timeout handler completes before returning, allowing callers to free a k_work_delayable object that work_timeout() subsequently dereferences. The race exists exclusively in SMP builds; work_timeout() performs a use-after-free read of the freed object's flags and, if the memory slot has been reused so the bail check passes, a use-after-free write to wp->flags and a submit against a stale dw->queue pointer. No public exploit has been identified and the vulnerability is absent from the CISA KEV catalog; exploitation is probabilistic and gated on kernel-mode code execution with influence over subsystem work-item teardown timing.
Out-of-bounds write in Zephyr RTOS's LoRaWAN Fragmented Data Block Transport service corrupts the Semtech/LoRaMAC-node decoder's internal MatrixM2B recovery-matrix state when a DATA_FRAGMENT command carries frag_index_n = 0, underflowing the 1-indexed counter arithmetic to array index -1. Impact is constrained to denial of an active FUOTA (Firmware Update Over The Air) session and decoder state corruption - not code execution - despite 'RCE' appearing in the intelligence metadata tags, which directly contradicts the CVE description. No public exploit has been identified and this vulnerability is not listed in CISA KEV.
Out-of-bounds write in IBM i 7.3 through 7.6 enables a local, low-privileged attacker to execute arbitrary code or trigger a denial of service via improper bounds checking. The vulnerability is classified under CWE-787 and carries tags for RCE, memory corruption, and buffer overflow, indicating a classic memory safety failure in a privileged operating environment. No public exploit or CISA KEV listing has been identified at time of analysis, and IBM has released a patch.
Remote denial of service in IBM i 7.3 through 7.6 is achievable by an unauthenticated network attacker exploiting an out-of-bounds write (CWE-787) in a network-facing component, resulting in limited availability and integrity impact. The CVSS vector (AV:N/AC:H/PR:N/UI:N/S:U) characterizes this as network-exploitable without credentials but requiring high attack complexity, substantially constraining real-world exploitability. No public exploit code has been identified at time of analysis, and IBM has released a patch addressed through its support advisory portal.
Sensitive information disclosure in IBM i versions 7.3 through 7.6 allows a remote authenticated attacker to read heap memory contents by triggering a heap buffer overflow in a vulnerable network-accessible component. The CVSS vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N confirms the attack is network-delivered with low-privilege authentication and yields limited but real confidentiality exposure with no integrity or availability impact. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; IBM has released a patch via PTF advisory and affected customers should apply it as a medium-priority remediation.
Stack-based buffer overflow in IBM i 7.3 through 7.6 allows a remote attacker with low-privileged network access to crash the system, causing a denial of service. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) confirms network reachability at low complexity, but impact is limited strictly to availability - no confidentiality or integrity consequences are indicated. IBM has released a patch; no public exploit or active exploitation has been identified at time of analysis.
Buffer overflow in IBM i 7.3 through 7.6 enables remote authenticated attackers to obtain sensitive information from the system. The vulnerability (CWE-787, out-of-bounds write) exposes memory contents under network-accessible conditions, with IBM confirming a patch is available. No public exploit code or active exploitation in CISA KEV has been identified at time of analysis, and EPSS data was not provided.
Wireshark 4.6.0 through 4.6.7 on Windows crashes when parsing malformed Ixia IxVeriWave capture files or Vector Informatik BLF files, resulting in denial of service via an out-of-bounds write (CWE-787). The vulnerability requires a user to open a crafted file, making it a user-assisted local attack. No public exploit code or active exploitation has been identified at time of analysis.
Out-of-bounds write in Palo Alto Networks GlobalProtect app exposes Windows, macOS, and Linux endpoints to arbitrary code execution at SYSTEM or root privilege levels when clients connect to an attacker-controlled rogue gateway or are subjected to a man-in-the-middle attack. The vulnerability resides in the client-side VPN agent's processing of gateway-supplied data, where a crafted response can corrupt memory and hijack execution. No public exploit has been identified at time of analysis, and CISA has not confirmed active exploitation, but full confidentiality, integrity, and availability compromise is possible on any affected endpoint that connects through a manipulated gateway.
IBM Security Verify Access and IBM Verify Identity Access - across both traditional software and container deployments - expose a Use After Free (CWE-416) memory corruption flaw in the Reverse Proxy component that authenticated network attackers can trigger under certain non-default configurations to cause a denial of service. The vulnerability carries a low CVSS base score of 3.1, reflecting high attack complexity and impact limited strictly to availability, with no confidentiality or integrity exposure. No public exploit code or active exploitation has been identified at time of analysis.
Out-of-bounds write in the Base64 decoder of Amazon's aws-sdk-cpp (all versions before 1.11.862) exposes applications to heap memory corruption or crash when processing attacker-supplied Base64-encoded content. Remote authenticated attackers can trigger the defect by submitting crafted input to any application built on this SDK that routes user-controlled data through the affected decoder path. No public exploit code has been identified at time of analysis, and the vulnerability has not been added to the CISA KEV catalog, though the CWE-787 heap write class carries inherent tail risk beyond the denial-of-service primary impact.
Use-After-Free vulnerabilities in the GNU linker (ld) component of binutils crash the linker process when processing crafted object or archive files during LTO-enabled linking on Red Hat Enterprise Linux systems. The flaws exist at three distinct dereference points in add_archive_element() in ld/ldmain.c, where plugin_maybe_claim() frees the BFD object but the caller retains dangling pointers that are subsequently accessed. The attack surface is confined to build-time environments, with the primary realistic threat being a supply chain attack introducing a malicious object file into CI/CD pipelines or developer build systems; no public exploit code or active exploitation has been confirmed at time of analysis.
Out-of-bounds write in Zephyr RTOS's llext subsystem allows a local attacker with low privileges to corrupt supervisor-context memory by loading a crafted relocatable ELF extension on Xtensa targets. The vulnerability in llext_link_plt() (subsys/llext/llext_link.c) occurs before any extension code executes - at link time - meaning sandbox protections are bypassed entirely. Exploitation complexity is high (CVSS AC:H) due to constraints on the write value, no public exploit code or CISA KEV listing exists at time of analysis, and impact is confined to deployments using llext on Xtensa architecture.
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix address space mismatch in kexec command line lookup When searching the loaded segments for the "kexec" command line marker, the kexec_load(2) path (file_mode == 0) passes the user-space segment buffer straight to strncmp() through a bogus (char __user *) cast. This dereferences a user pointer in kernel context, which is wrong and is flagged by sparse: arch/loongarch/kernel/machine_kexec.c:84:51: sparse: incorrect type in argument 2 (different address spaces) @@ expected char const * @@ got char [noderef] __user * Here copy the marker-sized prefix of each segment into a small on-stack buffer with copy_from_user() before comparing, and skip segments that fault. The subsequent copy_from_user() that stages the full command line into the safe area is left unchanged.
Use-after-free (CWE-416) in OpenSSH's ssh client component affects all releases before version 10.5, triggered when a specific pair of remote-forwarding operations occur concurrently, causing access to freed realloc'd memory. A malicious or compromised SSH server could exploit this race condition against a connecting client to achieve partial information disclosure or limited memory corruption. No public exploit has been identified and CISA SSVC rates exploitation as none with partial technical impact, consistent with the moderate CVSS score of 4.8.
Remote code execution in Microsoft Edge (Chromium-based) below version 151.0.4129.78 stems from a type confusion flaw (CWE-843) in the browser engine, exploitable over the network when a user visits or interacts with attacker-controlled content. The vendor has confirmed patch availability and the flaw is tagged as causing memory corruption, which aligns with the typical consequence of type confusion in browser engines. No active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, though the unauthenticated network vector with low attack complexity warrants prioritized patching in enterprise environments.
Use-after-free in MongoDB Server's geospatial validation subsystem allows an authenticated user with write privileges to crash the database server through concurrent operations against a collection using a specific validator type. Affected branches are MongoDB 7.0 (prior to 7.0.40), 8.0 (prior to 8.0.29), and 8.3.x (prior to 8.3.8), per EUVD advisory EUVD-2026-56913. No public exploit code exists and SSVC assessment indicates no current exploitation activity; patched releases are available from MongoDB.
Use-After-Free in the AMD Ryzen Master Utility Driver exposes kernel memory to a locally authenticated, high-privileged attacker, with the primary confirmed impact being system availability loss. The vulnerability (CWE-416) resides within the driver component bundled with both the Ryzen Master application and its Monitoring SDK, affecting all versions prior to the patched releases. No public exploit code or active exploitation has been identified at time of analysis, and the CVSS 4.0 score of 5.6 reflects the restricted local, high-privilege attack surface despite the kernel-level nature of the flaw.
Privilege escalation via use-after-free in the Windows Kernel affects Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025, requiring physical device access to exploit. An attacker with physical proximity can trigger kernel memory corruption under high-complexity conditions to gain full control of the affected system, achieving complete confidentiality, integrity, and availability impact. No public exploit code has been identified at time of analysis, and CISA SSVC confirms exploitation status as none.
Out-of-bounds write (CWE-787) in Intel Slim Bootloader firmware enables a denial of service condition on the local system. Exploitation requires a privileged local account and the presence of specific attack preconditions (AT:P per CVSS 4.0), and impact is confined to low availability on the vulnerable system with no confidentiality or integrity consequences. Intel disclosed this issue through advisory INTEL-SA-01475 with a CVSS 4.0 base score of 1.8; no public exploit code exists and no CISA KEV listing has been identified at time of analysis.
Use-after-free in the kernel-mode (Ring 0) driver component of Intel PROSet/Wireless WiFi Software for Windows enables a local denial-of-service condition by crashing the affected system. The flaw resides in the most privileged execution ring on x86/x64, meaning a successful trigger causes a kernel panic (BSOD) with no containment boundary below the OS. No active exploitation has been confirmed by CISA KEV, no public exploit code has been identified at time of analysis, and the combination of local-only access with high attack complexity substantially constrains real-world risk.
Out-of-bounds write in Intel PROSet/Wireless WiFi Software for Windows (Ring 2: Device Drivers) enables a denial-of-service condition exploitable from adjacent network position without authentication. The memory corruption flaw in the Windows WiFi driver stack can be triggered with passive user interaction, causing high availability impact to the vulnerable system and a residual low availability impact to subsequently connected systems. No public exploit code has been identified at time of analysis, and Intel has published advisory INTEL-SA-01422 addressing this issue.
Use-after-free in Vim's JSON channel parsing (versions 9.2.0511 through 9.2.0843) causes the socketserver process to crash when processing malformed JSON messages that straddle read-buffer boundaries. The stale pointer p in json_decode_item() is invalidated when channel_fill() frees the underlying buffer mid-parse; the error-reporting code then reads freed memory, producing a crash with no code-execution or data-exfiltration potential. No active exploitation is confirmed and no public exploit code has been identified; vendor-released patch v9.2.0844 resolves the flaw.
Heap out-of-bounds write in Tesseract OCR engine prior to 5.5.3 is triggered by a crafted LSTM .traineddata model file that causes a signed integer multiplication overflow in Convolve::DeSerialize, undersizing the forward-pass output buffer while write operations use the original unwrapped element count. Any application or user that loads an attacker-controlled model file is exposed to memory corruption that can lead to arbitrary code execution or process crash in the context of the OCR engine. No public exploit code has been identified at time of analysis, no CISA KEV listing exists, and a vendor-confirmed fix is available in Tesseract 5.5.3.
Out-of-bounds heap write in Zephyr RTOS's USB device-next CDC NCM class handler allows any physical USB host to corrupt the device's shared network buffer pool by issuing standard GET_NTB_PARAMETERS or GET_NTB_INPUT_SIZE control requests with a wLength field smaller than the response structure size. The overflow is bounded at up to 27 bytes and writes only fixed device constants, making its primary impact denial of service of the USB stack rather than arbitrary code execution. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; however, exploitation requires only physical USB access to a device built with the opt-in device_next stack and CDC NCM class.
Use-after-free in Zephyr RTOS kernel queue peek operations (z_impl_k_queue_peek_head and z_impl_k_queue_peek_tail in kernel/queue.c) allows a local low-privileged thread to obtain a dangling pointer to freed heap memory by winning a race against a concurrent k_queue_get call on a shared queue. Successful exploitation - requiring SMP or preemptive concurrency - can leak a stale heap pointer or crash the system when the returned dangling pointer is subsequently consumed as a live buffer in the net_buf, Bluetooth, USB, or networking subsystems. No public exploit exists and no active exploitation is confirmed; CVSS scores this at 3.6 (Low), accurately reflecting the narrow race window and local-only attack surface.
Heap out-of-bounds write in RadiAnt DICOM Viewer is triggered when processing JPEG-compressed pixel data embedded in a crafted DICOM file, potentially enabling arbitrary code execution on the victim's workstation. Reported to CISA ICS-CERT as a medical device advisory (ICSMA-26-218-01), the vulnerability requires no privileges and only passive user interaction - consistent with file-preview or file-open workflows common in clinical imaging environments. The provided CVSS 4.0 score of 5.3 rates impact as availability-only (VA:L), which conflicts materially with the described RCE potential; this discrepancy is significant and should be independently verified. No public exploit code or CISA KEV listing has been confirmed at time of analysis.
Use-after-free memory corruption in open62541's example client code allows a local low-privileged user to cause memory corruption with potential for denial of service or limited code execution. The vulnerability resides in the UA_Client_getRemoteDataTypes function within the examples/custom_datatype/client_types_custom.c file - notably example/sample code rather than the core library - at commit ca356b088ada7dee824d1b4acd07c1ff07ce242b. A publicly available proof-of-concept exploit exists, though the project closed the issue report citing improper disclosure channel, leaving no official patch or advisory. No confirmed active exploitation (CISA KEV absent), but the CVSS 4.0 E:P modifier reflects the published POC.
Use-after-free in Zephyr RTOS 4.4.0's Bluetooth ATT host layer (subsys/bluetooth/host/att.c) allows an adjacent unauthenticated peer to crash the Bluetooth host or potentially corrupt live memory by disconnecting while an ATT PDU is in-flight. The tx_meta_data_storage[] array retains a dangling att_chan pointer after L2CAP tears down and frees the channel slab slot, and the deferred att_tx_destroy_work_handler running on the system workqueue dereferences that freed pointer. No pairing or special privileges are required - a routine ATT connection is sufficient to reach the vulnerable code path. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Off-by-one memory corruption in popt's poptStuffArgs function allows a local low-privileged attacker to overwrite adjacent memory and potentially execute arbitrary code within any host application that unsafely processes the corrupted argument data. All supported Red Hat Enterprise Linux releases (6 through 10), Red Hat Hardened Images, and OpenShift Container Platform 4 ship the affected library. No public exploit code has been identified and no CISA KEV listing exists; exploitation requires high-complexity triggering conditions, making this a routine patch priority rather than an emergency response item.
Out-of-bounds write in the wifi subsystem of MediaTek MT6890, MT6990, and MT6988 chipsets enables a local denial of service, crashing the wifi component or device. Exploitation requires that the attacker has already obtained System-level privilege on the affected device - an extremely high bar that makes this a post-exploitation nuisance rather than an initial access vector. EPSS sits at 0.13% (3rd percentile), no public exploit code exists, and the vulnerability is not listed in the CISA KEV catalog, all consistent with the substantial privilege prerequisite.
Out-of-bounds write in the 'med' media processing component of specific MediaTek SoC chipsets (MT6890, MT6988, MT6990, MT2735, MT2737) enables a local attacker with standard user privileges to crash the device, causing a denial of service. The root cause is an incorrect bounds check (CWE-787) that allows a write past allocated buffer boundaries, corrupting memory. No public exploit is identified at time of analysis, and EPSS at 0.15% (4th percentile) combined with SSVC exploitation status of 'none' signals very low real-world exploitation probability.
Out-of-bounds write in MediaTek's HFRP component on the MT6993 chipset enables local privilege escalation beyond System-level access, confirmed via MediaTek's August 2026 security bulletin. The flaw stems from a missing bounds check (CWE-787), requiring an attacker who has already achieved System privilege to trigger further escalation - a post-compromise lateral movement primitive rather than an initial access vector. No public exploit code and no KEV listing have been identified; EPSS sits at the 3rd percentile, consistent with SSVC's 'exploitation: none' finding.
Out-of-bounds write in MediaTek's GeniZone Trusted Execution Environment (TEE) component enables local privilege escalation across 14 distinct MediaTek chipsets. An attacker who has already achieved System-level privilege on an affected Android device can exploit a missing bounds check to write outside intended memory boundaries within the secure enclave, gaining confidentiality and integrity access beyond what System privilege normally permits. No public exploit has been identified at time of analysis, and the EPSS score of 0.13% (3rd percentile) reflects low observed exploitation probability; however, the pre-existing System privilege prerequisite substantially narrows the realistic attack surface.
Out-of-bounds write in MediaTek's GenieZone hypervisor component enables local privilege escalation beyond System-level access on a wide range of MediaTek mobile chipsets. Exploitation is constrained to attackers who have already obtained System privileges, making this a secondary step in a multi-stage attack chain rather than an initial foothold technique. No public exploit code exists and EPSS of 0.13% (3rd percentile) confirms negligible real-world exploitation activity; no CISA KEV listing at time of analysis.
Heap buffer overflow in MediaTek's Audio Hardware Abstraction Layer (HAL) across six chipset families enables local denial of service on affected mobile and automotive platforms. A local user-level process can trigger an out-of-bounds write in the Audio HAL, crashing the audio subsystem with no user interaction required. No public exploit exists and EPSS sits at 0.15% (5th percentile), consistent with SSVC's 'none' exploitation status and the strictly local, availability-only impact profile.
Out-of-bounds write in the MediaTek display driver allows a local attacker who has already obtained System-level privilege to further escalate privileges on affected Android devices. The vulnerability stems from a missing bounds check (CWE-787) in display subsystem code across at least ten MediaTek chipsets, including MT8910, MT8188, MT8799, and MT6991 among others. No public exploit or active exploitation (CISA KEV) is identified at time of analysis; EPSS score of 0.14% (4th percentile) and SSVC exploitation rating of 'none' both confirm this remains an undemonstrated threat as of the August 2026 advisory.
Local denial of service in MediaTek's ccci (Cross Core Communication Interface) kernel driver affects MT6986, MT6988, and MT6813 chipsets through a missing bounds check that enables an out-of-bounds memory access. A local user-privileged attacker - such as a malicious Android application - can crash the kernel, causing device unavailability without requiring user interaction. No public exploit code exists and EPSS probability is 0.16% (6th percentile); SSVC exploitation status is confirmed 'none,' aligning all risk signals toward low immediate threat.
Local privilege escalation in MediaTek's display subsystem affects 17 chipset variants used in Android devices, allowing an attacker who has already obtained System-level privilege to exploit a missing bounds check (CWE-787) and write out of bounds in display memory, achieving high confidentiality and integrity impact. The CVSS vector (PR:H/AV:L) confirms this is not an initial-access vector - it is a post-compromise escalation step requiring pre-existing System privilege. No public exploit has been identified, EPSS stands at 0.14% (4th percentile), and the vulnerability is not listed in CISA KEV, consistent with SSVC's exploitation status of 'none.'
Local privilege escalation in the MediaTek display driver allows an attacker who already holds System-level privileges to further escalate via a use-after-free memory corruption condition, potentially achieving kernel-level access. Seventeen MediaTek SoC models used across Android devices are affected, disclosed in MediaTek's August 2026 security bulletin with Patch ID ALPS11019722. No public exploit code exists and EPSS at 0.14% (4th percentile) confirms negligible current exploitation probability; this vulnerability is not in the CISA KEV catalog.
Out-of-bounds write in MediaTek's Trusted Firmware-A (TFA) component allows a local attacker already holding System-level privilege to crash the device, causing a denial of service. Affected hardware includes MediaTek Dimensity and Helio chipsets MT6986D, MT6986, and MT6982VB. No public exploit code has been identified and CISA KEV does not list this vulnerability, consistent with its low EPSS score of 0.14% and SSVC exploitation status of none.
Out-of-bounds write in the MediaTek Download Agent (DA) firmware component across eight chipset families allows an attacker with physical device access to trigger a local denial of service by sending a crafted payload while the device is in DA mode. Affected chipsets span mobile SoCs (MT6880, MT6890, MT6990, MT6988, MT6986, MT6813) and modem/automotive chipsets (MT2735, MT2737), broadening the potential device footprint across Android smartphones and connected vehicle platforms. No public exploit code exists, EPSS sits at the 6th percentile (0.16%), SSVC confirms no known exploitation, and the physical access prerequisite fundamentally constrains real-world risk.
Local privilege escalation in MediaTek's apusys AI Processing Unit subsystem on MT8196 and MT8366 chipsets allows an attacker already holding System-level privileges to further escalate by exploiting a confused deputy flaw - likely realized through an out-of-bounds write (CWE-787) - achieving high confidentiality and integrity impact on the vulnerable system. Disclosed by MediaTek in their August 2026 Product Security Bulletin, a vendor patch is available under Patch ID AUTO00833804. No public exploit has been identified at time of analysis, and an EPSS of 0.14% at the 4th percentile reflects negligible probability of widespread exploitation.
Secure boot heap buffer overflow in MediaTek chipsets MT2737, MT6880, MT6890, and MT6990 enables local privilege escalation by an attacker with physical device access. The vulnerability exists at the pre-OS firmware layer, where a write beyond allocated heap boundaries can corrupt boot verification logic and permit execution of unsigned or attacker-controlled code. No active exploitation has been confirmed - the vulnerability is absent from CISA KEV, and the EPSS score of 0.16% (6th percentile) is consistent with the hard physical access prerequisite sharply limiting opportunistic exploitation.
Out-of-bounds write in the MediaTek HEVC video decoder enables further privilege escalation on devices running MT6761, MT8766, and MT8768 chipsets. The flaw, rooted in an integer overflow during HEVC bitstream processing, can be triggered without user interaction but only by an actor who already holds System-level privilege on the device. No public exploit code has been identified at time of analysis, and EPSS sits at 0.18% (8th percentile), consistent with SSVC's 'Exploitation: none' assessment - though SSVC rates Technical Impact as total, reflecting the severity of what a successful second-stage exploit could achieve.
Cross-buffer memory aliasing in msgpack-ruby prior to 1.8.2 allows same-process code to read or corrupt data belonging to a separate MessagePack::Buffer instance via a use-after-free in the rmem slab allocator. MessagePack::Buffer#clear returns a 4 KiB rmem page to the shared pool but leaves rmem_last, rmem_end, and rmem_owner pointing into the freed page; a subsequent write on the cleared buffer and a concurrent second Buffer allocation can claim the same physical page, creating a memory alias that exposes the second buffer's serialized bytes. A PoC is included in the vendor advisory (GHSA-4mrv-5p47-p938); no public exploit identified at time of analysis beyond that PoC, and the CVE is not in CISA KEV.
Use-after-free in Chrome's DataTransfer component on Windows exposes process memory to local attackers who can deliver a crafted HTML page to a victim. The flaw affects all Chrome versions on Windows prior to 151.0.7922.72 and results in high-confidence confidentiality loss with no integrity or availability impact. No public exploit code has been identified and EPSS sits at 0.11% (2nd percentile), consistent with CISA SSVC classifying exploitation as 'none' and technical impact as 'partial' - making this a low operational priority despite the High confidentiality CVSS sub-score.
Sandbox escape in Google Chrome's ANGLE graphics layer on Android enables an attacker who has already compromised the renderer process to break out of the Chrome sandbox via a crafted HTML page. Affected versions are all Chrome for Android releases prior to 151.0.7922.72. This is a second-stage exploit primitive requiring a prior renderer compromise; no public exploit code exists and SSVC reports exploitation as none, keeping real-world risk moderate despite the scope-change nature of the flaw.
Sandbox escape in Google Chrome for Android (prior to 151.0.7922.72) stems from a type confusion flaw (CWE-843) in the Tab component, enabling an attacker who has already compromised the renderer process to break out of Chrome's security sandbox via a crafted HTML page. This is a second-stage exploit primitive requiring renderer pre-compromise, reflected in the AC:H and S:C CVSS metrics. No active exploitation has been confirmed (not in CISA KEV), and EPSS sits at 0.20% (10th percentile), consistent with a chained, complex attack rather than opportunistic mass exploitation. Patch is available as Chrome 151.0.7922.72.
Use-after-free in the GPU process on macOS enables sandbox escape in Google Chrome versions prior to 151.0.7922.72, but only when an attacker has already achieved renderer process compromise. This is a second-stage exploit primitive - it extends an existing renderer compromise across the sandbox boundary into the GPU process, potentially allowing arbitrary code execution outside Chrome's sandbox on macOS. No public exploit code has been identified and EPSS sits at 0.21% (11th percentile), indicating low observed exploitation probability; however, sandbox escapes are a critical capability for attackers chaining browser exploit kits.
Use-after-free in the Bluetooth component of Google Chrome on Android prior to 151.0.7922.72 enables a sandbox escape for remote attackers who have already achieved renderer process compromise. Exploitation requires delivering a crafted HTML page to a victim user and successfully triggering a memory corruption condition in the Bluetooth subsystem, allowing code execution outside the renderer sandbox. No public exploit code has been identified at time of analysis, and EPSS at 0.21% (11th percentile) indicates low observed exploitation probability; no CISA KEV listing is present.
Buffer overrun in the Apache Traffic Server multiplexer plugin's chunk-decode logic allows network-adjacent attackers who can influence upstream origin responses to cause denial of service across versions 8.0.0 through 10.1.3. The flaw is classified as CWE-787 (Out-of-bounds Write) and is constrained to availability impact only - no code execution or data exposure is indicated. No public exploit or CISA KEV listing has been identified, and the CVSS 3.7 Low score reflects meaningful real-world limitations, primarily the high attack complexity imposed by the upstream-input dependency.
Use-after-free in the sqlite3 Ruby gem (published as both sqlite3-ruby and sqlite3) versions 2.1.0 through 2.9.4 lets an aggregate function be invoked through a still-open prepared statement after its Database object has been explicitly closed, producing an invalid memory read and a segmentation fault that crashes the Ruby process. Exploitation requires an in-process API-misuse pattern in the host application itself - local, high-complexity, low-privileged per the assessed CVSS:3.1 vector (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L) - with no remote or network vector and no attacker-supplied input. No public exploit identified at time of analysis (EPSS 0.11%, CISA SSVC exploitation: none, Automatable: no); the maintainers classify it as Low severity, describing a reliably reproducible crash after garbage collection rather than a proven denial-of-service or code-execution primitive.
A use-after-free vulnerability in the sqlite3-ruby gem allows an attacker to crash the Ruby process by defining a custom SQLite function with the same name but a different number of arguments or text encoding, leading to an invalid memory read and segmentation fault. The issue affects versions prior to 2.9.5 and was assessed as low severity by the maintainers due to the specific code pattern required for exploitation.
Memory corruption in Xen allows guest VMs with Populated on Demand (PoD) enabled to cause denial of service by attempting to reclaim non-guest memory pages, corrupting hypervisor memory management state. No public exploit identified and SSVC indicates no current exploitation, but the flaw is automatable with partial technical impact.

Denial of service in SQLite 3.41 due to a use-after-free in the JSON extraction function. A local unauthenticated attacker can trigger a crash by supplying a malicious JSON input, causing the host application to terminate. No active exploitation has been confirmed in the wild, but public exploit proof-of-concept may exist.
A heap buffer over-write in ImageMagick's fx operation can be triggered via a crafted argument when processing images with the Magick.NET library, leading to a denial of service. Affected versions of the Magick.NET NuGet package (before 14.15.0) are confirmed vulnerable; no active exploitation or public proof-of-concept has been identified. The vulnerability has a medium CVSS score (5.0) with local attack vector and user interaction required.
Memory corruption via use-after-free in NLnet Labs Unbound 1.25.0-1.25.1 can cause a DNS resolver crash under specific, non-default configurations when the server is under load. The flaw originates from a regression introduced in a fix enabling 'respip' and 'dns64' module interoperability: subqueries receive a shallow copy of the active view name, and if the parent query is evicted (jostled) before the subquery completes, the dangling reference causes memory corruption. No public exploit code exists and no confirmed active exploitation (CISA KEV) has been identified; the vendor explicitly describes crash likelihood as low due to dependence on memory layout and allocator behavior.
Use-after-free in NLnet Labs Unbound 1.15.0 through 1.25.1 crashes the DNS daemon via a dangling pointer to a freed TLS server name string in the DNS-over-TLS forwarding path. A remote attacker with knowledge of the target resolver's configuration can trigger the crash by sustaining query pressure against the configured DoT zone while inducing a transient upstream connection failure, causing denial of service. No public exploit code exists and this vulnerability has not been confirmed as actively exploited, but the network-accessible attack surface (PR:N) makes it relevant to operators running internet-facing recursive resolvers with DoT forwarding.
Heap use-after-free in the SyncTeX parser shipped with TeX Live and embedded by GNOME Evince allows crash or potential arbitrary code execution when a user opens a malformed .synctex or .synctex.gz file. The flaw stems from a NULL parent pointer condition in _synctex_post_process_ref() that bypasses node detachment, causing recursive freeing of live tree nodes and leaving dangling pointers later accessed during document parsing. Exploitation requires local file access and active user interaction (UI:A per CVSS 4.0), no public exploit has been confirmed, but a detailed researcher blog post by the discoverer (Fatih Çelik) is publicly available and the RCE tag suggests demonstrated impact potential.
Out-of-bounds memory corruption in kronosnet's packet reassembly engine (versions ≤ 1.34) enables a remote, unauthenticated network attacker to crash the kronosnet process or cause heap corruption by transmitting malformed fragmented packets carrying invalid sequence numbers. Affected deployments span Red Hat Enterprise Linux 8, 9, and 10, and Red Hat OpenShift Container Platform 4, making this relevant to HA clustering infrastructure that depends on kronosnet for inter-node communication via Corosync or Pacemaker. No public exploit code and no active exploitation have been identified at time of analysis, though the network-accessible, no-privilege-required attack path elevates operational risk for clustered environments despite the AC:H complexity rating.
Out-of-bounds write in davenardella snap7 up to version 1.4.3 allows network-authenticated attackers to corrupt memory by supplying a crafted PDULength value during S7 protocol negotiation. The vulnerable function TSnap7Peer::NegotiatePDULength in src/core/s7_peer.cpp fails to enforce bounds on the PDULength argument, enabling writes beyond the allocated buffer boundary. A public proof-of-concept exploit is available on GitHub (issue #17), and the CVSS 4.0 E:P modifier confirms this - elevating practical risk above the medium base score, particularly in OT/ICS deployments where snap7 is commonly used to interface with Siemens S7 PLCs.
Out-of-bounds write in Bouncy Castle BC-LTS bcprov-lts8on affects ARM deployments running versions 2.73.0 through 2.73.12.0, with high confidentiality impact if successfully exploited. The flaw resides in ARM-specific native C implementations of SHA3 and SHAKE algorithms and is only triggered when an application accepts memoable SHA3/SHAKE cryptographic states from potentially untrusted external sources. No public exploit code exists and no active exploitation has been confirmed at time of analysis; the CVSS 4.0 score of 1.7 reflects the very narrow exploitation conditions required to reach this code path.
YAML::Syck before version 1.47 crashes the Perl interpreter when parsing a YAML document that redefines an anchor name, due to a use-after-free and double-free in the bundled libsyck C library. Any caller invoking Load() or LoadFile() on attacker-controlled YAML - a common pattern in Perl web frameworks and data-pipeline tooling - is exposed to a denial-of-service condition that aborts the interpreter process. No public exploit beyond the CPANSec-confirmed 7-byte trigger document exists and no CISA KEV listing is present, but the trivially short trigger makes reliable reproduction straightforward.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local attacker with high OS-level privileges to execute arbitrary code in System Management Mode (SMM) - a CPU execution context operating below the operating system and hypervisor with access to all system memory. Successful exploitation allows persistent firmware-level implants that survive OS reinstallation and defeat Secure Boot and standard endpoint detection tools. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, SMM code execution represents one of the highest-impact firmware attack primitives available to an advanced threat actor.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local privileged attacker to corrupt power management settings within System Management Mode, a CPU execution context operating below the OS kernel at Ring -2. Successful exploitation could allow persistent firmware-level tampering that survives OS reinstalls and reboots. No public exploit has been identified at time of analysis, and exploitation requires pre-existing high OS-level privileges, substantially limiting real-world risk to post-compromise scenarios.
Use-after-free in ESET's Linux security product kernel components enables a local high-privileged attacker to trigger a kernel panic, causing a complete system crash and denial of service. Both ESET Endpoint Antivirus for Linux and ESET Server Security for Linux are affected across unspecified versions, per ESET's own customer advisory. No public exploit code has been identified and CISA has not added this to the Known Exploited Vulnerabilities catalog; however, server-deployed AV with kernel-level hooks makes the DoS impact operationally significant in production environments.
Heap overflow in Absolute Security Secure Access client certificate parsing causes a local denial of service. Versions prior to 14.55 are affected. An attacker who already holds local administrator privileges on a managed endpoint can trigger the overflow to crash the Secure Access client, effectively disabling it on that machine. No public exploit code has been identified, and this vulnerability is not listed in the CISA KEV catalog.
Use-after-free in ImageMagick's FreeType integration path allows remote denial of service against image processing pipelines using vulnerable 6.x or 7.x releases. When FreeType initialization fails during an image processing operation, the affected code path neglects to exit cleanly and continues referencing already-freed memory, causing process corruption or crash. No public exploit identified at time of analysis; the CVSS 4.0 score of 6.3 with AC:H and AT:P reflects meaningful preconditions required to trigger the failure path.
Denial of service in BusyBox 1.38.0 arises from a use-after-free in the awk_sub() routine of the AWK applet (editors/awk.c), allowing an attacker who can supply a crafted AWK script to crash the busybox awk process. The flaw is a memory-corruption bug (CWE-416) with availability-only impact and no confidentiality or integrity consequences. There is no public exploit identified at time of analysis, it is not listed in CISA KEV, and its EPSS score is low (0.14%, 4th percentile).
Type confusion (CWE-843) in Microsoft SQL Server 2025 enables authenticated, low-privileged network attackers to disclose sensitive server-side information. The CVSS vector (AV:N/PR:L/C:H) confirms that any authorized database user - regardless of their data access permissions - can potentially trigger the flaw remotely with no user interaction required. No public exploit code or CISA KEV listing exists at time of analysis, but the high confidentiality impact and low access complexity make patching a meaningful priority for organizations running SQL Server 2025.
Use-after-free in the Windows Virtual Filtering Platform (VFP) enables authenticated network attackers to crash affected Windows endpoints and servers, resulting in a denial-of-service condition. The vulnerability spans a broad range of supported Windows 10, Windows 11, and Windows Server releases through 2025, making patch prioritization important despite the medium CVSS score. No public exploit code or active exploitation has been identified at time of analysis, and SSVC classifies this as not automatable with partial technical impact.
Privilege escalation via physical attack in the Windows Cloud Files Mini Filter Driver (cldflt.sys) affects all major Windows 10, Windows 11, and Windows Server releases through 2025. The use-after-free memory corruption flaw (CWE-416) in the kernel-mode driver allows an attacker with physical access to the device to escalate privileges to SYSTEM level, achieving full confidentiality, integrity, and availability compromise. No public exploit code has been identified and CISA has not listed this in KEV, but the SSVC assessment notes total technical impact - the physical access requirement is the primary limiting factor, not the vulnerability's severity once that barrier is cleared.
Type confusion in the Windows Composite Image File System (CimFS) kernel driver enables local, low-privileged authenticated users to disclose protected memory contents on widely-deployed Windows 10, Windows 11, and Windows Server platforms. The flaw (CWE-843) causes the driver to access a kernel resource via an incompatible type, resulting in unintended memory reads with high confidentiality impact. No public exploit or active exploitation has been confirmed - SSVC lists exploitation as 'none,' EPSS stands at 0.29% (21st percentile), and the vulnerability is absent from the CISA KEV catalog - placing real-world risk in the lower-medium tier despite the C:H CVSS sub-score.
Privilege escalation via use-after-free in the Windows USB Print Driver affects Windows 11 (versions 24H2, 25H2, 26H1) and Windows Server 2025, requiring physical access to exploit. An attacker with hands-on access to a target machine can trigger a memory corruption condition through the USB print subsystem to achieve full local privilege escalation - High confidentiality, integrity, and availability impact per CVSS. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Use-after-free memory corruption in gawk's do_getline_redir() routine within io.c allows a local attacker to crash the gawk process, causing a denial of service. All gawk versions 5.4.0 and below are affected, as confirmed by CERT-PL and an upstream patch commit. No active exploitation has been identified (not in CISA KEV), and the impact is confined to availability - no confidentiality or integrity effects have been demonstrated.
Out-of-bounds stack write in Zephyr's nRF70 Wi-Fi driver exposes embedded systems to memory corruption when the nRF70 co-processor returns a power-save event with more than eight TWT flow entries. The vulnerable function `nrf_wifi_event_proc_get_power_save_info()` blindly copies co-processor-supplied TWT entries into a fixed 8-element stack array without validating `num_twt_flows` against `WIFI_MAX_TWT_FLOWS`, enabling heap/stack corruption of approximately 40 bytes per excess entry. No public exploit code exists and the flaw is not listed in CISA KEV, but the adjacent-network attack vector and the indirect over-the-air influence path via a rogue AP manipulating TWT sessions make this a meaningful risk in Wi-Fi 6 (802.11ax) deployment environments running Zephyr with `CONFIG_NRF70_STA_MODE`.
JIT miscompilation in Firefox's SpiderMonkey JavaScript engine exposes sensitive memory to remote attackers via crafted web content. The CWE-843 (type confusion) root cause means the JIT compiler generates native code that accesses a JavaScript value as the wrong type, resulting in a high-confidentiality information disclosure. Vendor-released patches are available in Firefox 154, Firefox ESR 140.14, and Firefox ESR 153.1; no public exploit or CISA KEV listing has been identified at time of analysis.
Race condition and use-after-free memory corruption in Mozilla Firefox's Graphics component allows remote unauthenticated attackers to achieve limited confidentiality and integrity impact when a user visits a malicious web page.

No public exploit code has been identified and CISA has not listed this in KEV; the SSVC framework rates exploitation status as none and marks it not automatable.
Unexpected process termination in Apple iOS/iPadOS and macOS Tahoe can be triggered remotely by luring a user to visit maliciously crafted web content, exploiting a use-after-free flaw in the web content rendering engine. The vulnerability affects iOS and iPadOS versions prior to 26.6.1 and macOS Tahoe prior to 26.6.2, with impact limited to availability - crashing the affected browser or WebKit-based process - and no confirmed confidentiality or integrity loss. No public exploit code or CISA KEV listing is identified at time of analysis, though the low-complexity, network-accessible attack surface warrants prompt patching given the broad Apple device install base.
Use-after-free memory corruption in Apple's WebKit web rendering engine crashes the browser process when handling maliciously crafted web content on iOS, iPadOS, and macOS Tahoe. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) confirms network-reachable exploitation limited to availability impact - a process crash - with no confidentiality or integrity compromise. Apple has released fixes across both the legacy iOS 18.x branch and the current iOS 26.x line, indicating broad exposure across the installed base. No active exploitation or public proof-of-concept has been identified at time of analysis.
Out-of-bounds stack read and write in the WNC-M14A2A LTE-M modem driver (wncm14a2a.c) within Zephyr RTOS versions 1.13.0 through below 4.4.2 allows a rogue cellular base station or RF attacker to crash the modem RX thread and leak adjacent stack memory without any application interaction. The defect fires automatically on receipt of an unsolicited %NOTIFYEV: event whose payload exceeds 39 bytes and lacks a quote character within the linearized region, causing scanning loop indices to walk past the fixed 40-byte stack buffer. While the write primitive is weakly controlled — limiting demonstrated impact to denial of service and stack disclosure — the CVE is tagged RCE by reporters, though the description explicitly states memory-safe code execution has not been demonstrated. No public exploit or CISA KEV listing exists at time of analysis.
Use-after-free in HarmonyOS 6.1.0's time and time zone module allows a local low-privileged attacker to crash the affected component, degrading availability. Exploitation is local and requires existing user-level access, limiting the realistic attacker pool to on-device processes or malicious apps. No public exploit code or active exploitation has been identified at time of analysis.
Memory corruption and denial of service in Zephyr RTOS's second-generation delayable work queue (kernel/work.c) arise because the documented safe-cancellation APIs-k_work_cancel_delayable_sync() and k_work_flush_delayable()-fail to block until an in-flight timeout handler completes before returning, allowing callers to free a k_work_delayable object that work_timeout() subsequently dereferences. The race exists exclusively in SMP builds; work_timeout() performs a use-after-free read of the freed object's flags and, if the memory slot has been reused so the bail check passes, a use-after-free write to wp->flags and a submit against a stale dw->queue pointer. No public exploit has been identified and the vulnerability is absent from the CISA KEV catalog; exploitation is probabilistic and gated on kernel-mode code execution with influence over subsystem work-item teardown timing.
Out-of-bounds write in Zephyr RTOS's LoRaWAN Fragmented Data Block Transport service corrupts the Semtech/LoRaMAC-node decoder's internal MatrixM2B recovery-matrix state when a DATA_FRAGMENT command carries frag_index_n = 0, underflowing the 1-indexed counter arithmetic to array index -1. Impact is constrained to denial of an active FUOTA (Firmware Update Over The Air) session and decoder state corruption - not code execution - despite 'RCE' appearing in the intelligence metadata tags, which directly contradicts the CVE description. No public exploit has been identified and this vulnerability is not listed in CISA KEV.
Out-of-bounds write in IBM i 7.3 through 7.6 enables a local, low-privileged attacker to execute arbitrary code or trigger a denial of service via improper bounds checking.

No public exploit or CISA KEV listing has been identified at time of analysis, and IBM has released a patch.
Remote denial of service in IBM i 7.3 through 7.6 is achievable by an unauthenticated network attacker exploiting an out-of-bounds write (CWE-787) in a network-facing component, resulting in limited availability and integrity impact. The CVSS vector (AV:N/AC:H/PR:N/UI:N/S:U) characterizes this as network-exploitable without credentials but requiring high attack complexity, substantially constraining real-world exploitability. No public exploit code has been identified at time of analysis, and IBM has released a patch addressed through its support advisory portal.
Sensitive information disclosure in IBM i versions 7.3 through 7.6 allows a remote authenticated attacker to read heap memory contents by triggering a heap buffer overflow in a vulnerable network-accessible component. The CVSS vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N confirms the attack is network-delivered with low-privilege authentication and yields limited but real confidentiality exposure with no integrity or availability impact. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; IBM has released a patch via PTF advisory and affected customers should apply it as a medium-priority remediation.
Stack-based buffer overflow in IBM i 7.3 through 7.6 allows a remote attacker with low-privileged network access to crash the system, causing a denial of service. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) confirms network reachability at low complexity, but impact is limited strictly to availability - no confidentiality or integrity consequences are indicated. IBM has released a patch; no public exploit or active exploitation has been identified at time of analysis.

The vulnerability requires a user to open a crafted file, making it a user-assisted local attack. No public exploit code or active exploitation has been identified at time of analysis.
Out-of-bounds write in Palo Alto Networks GlobalProtect app exposes Windows, macOS, and Linux endpoints to arbitrary code execution at SYSTEM or root privilege levels when clients connect to an attacker-controlled rogue gateway or are subjected to a man-in-the-middle attack. The vulnerability resides in the client-side VPN agent's processing of gateway-supplied data, where a crafted response can corrupt memory and hijack execution. No public exploit has been identified at time of analysis, and CISA has not confirmed active exploitation, but full confidentiality, integrity, and availability compromise is possible on any affected endpoint that connects through a manipulated gateway.
IBM Security Verify Access and IBM Verify Identity Access - across both traditional software and container deployments - expose a Use After Free (CWE-416) memory corruption flaw in the Reverse Proxy component that authenticated network attackers can trigger under certain non-default configurations to cause a denial of service. The vulnerability carries a low CVSS base score of 3.1, reflecting high attack complexity and impact limited strictly to availability, with no confidentiality or integrity exposure. No public exploit code or active exploitation has been identified at time of analysis.
Out-of-bounds write in the Base64 decoder of Amazon's aws-sdk-cpp (all versions before 1.11.862) exposes applications to heap memory corruption or crash when processing attacker-supplied Base64-encoded content. Remote authenticated attackers can trigger the defect by submitting crafted input to any application built on this SDK that routes user-controlled data through the affected decoder path. No public exploit code has been identified at time of analysis, and the vulnerability has not been added to the CISA KEV catalog, though the CWE-787 heap write class carries inherent tail risk beyond the denial-of-service primary impact.
Use-After-Free vulnerabilities in the GNU linker (ld) component of binutils crash the linker process when processing crafted object or archive files during LTO-enabled linking on Red Hat Enterprise Linux systems. The flaws exist at three distinct dereference points in add_archive_element() in ld/ldmain.c, where plugin_maybe_claim() frees the BFD object but the caller retains dangling pointers that are subsequently accessed. The attack surface is confined to build-time environments, with the primary realistic threat being a supply chain attack introducing a malicious object file into CI/CD pipelines or developer build systems; no public exploit code or active exploitation has been confirmed at time of analysis.
Out-of-bounds write in Zephyr RTOS's llext subsystem allows a local attacker with low privileges to corrupt supervisor-context memory by loading a crafted relocatable ELF extension on Xtensa targets. The vulnerability in llext_link_plt() (subsys/llext/llext_link.c) occurs before any extension code executes - at link time - meaning sandbox protections are bypassed entirely. Exploitation complexity is high (CVSS AC:H) due to constraints on the write value, no public exploit code or CISA KEV listing exists at time of analysis, and impact is confined to deployments using llext on Xtensa architecture.
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix address space mismatch in kexec command line lookup When searching the loaded segments for the "kexec" command line marker, the kexec_load(2) path (file_mode == 0) passes the user-space segment buffer straight to strncmp() through a bogus (char __user *) cast. This dereferences a user pointer in kernel context, which is wrong and is flagged by sparse: arch/loongarch/kernel/machine_kexec.c:84:51: sparse: incorrect type in argument 2 (different address spaces) @@ expected char const * @@ got char [noderef] __user * Here copy the marker-sized prefix of each segment into a small on-stack buffer with copy_from_user() before comparing, and skip segments that fault. The subsequent copy_from_user() that stages the full command line into the safe area is left unchanged.
Use-after-free (CWE-416) in OpenSSH's ssh client component affects all releases before version 10.5, triggered when a specific pair of remote-forwarding operations occur concurrently, causing access to freed realloc'd memory. A malicious or compromised SSH server could exploit this race condition against a connecting client to achieve partial information disclosure or limited memory corruption. No public exploit has been identified and CISA SSVC rates exploitation as none with partial technical impact, consistent with the moderate CVSS score of 4.8.
Remote code execution in Microsoft Edge (Chromium-based) below version 151.0.4129.78 stems from a type confusion flaw (CWE-843) in the browser engine, exploitable over the network when a user visits or interacts with attacker-controlled content. The vendor has confirmed patch availability and the flaw is tagged as causing memory corruption, which aligns with the typical consequence of type confusion in browser engines. No active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, though the unauthenticated network vector with low attack complexity warrants prioritized patching in enterprise environments.
Use-after-free in MongoDB Server's geospatial validation subsystem allows an authenticated user with write privileges to crash the database server through concurrent operations against a collection using a specific validator type. Affected branches are MongoDB 7.0 (prior to 7.0.40), 8.0 (prior to 8.0.29), and 8.3.x (prior to 8.3.8), per EUVD advisory EUVD-2026-56913. No public exploit code exists and SSVC assessment indicates no current exploitation activity; patched releases are available from MongoDB.

Intel disclosed this issue through advisory INTEL-SA-01475 with a CVSS 4.0 base score of 1.8; no public exploit code exists and no CISA KEV listing has been identified at time of analysis.
Use-after-free in the kernel-mode (Ring 0) driver component of Intel PROSet/Wireless WiFi Software for Windows enables a local denial-of-service condition by crashing the affected system. The flaw resides in the most privileged execution ring on x86/x64, meaning a successful trigger causes a kernel panic (BSOD) with no containment boundary below the OS. No active exploitation has been confirmed by CISA KEV, no public exploit code has been identified at time of analysis, and the combination of local-only access with high attack complexity substantially constrains real-world risk.
Out-of-bounds write in Intel PROSet/Wireless WiFi Software for Windows (Ring 2: Device Drivers) enables a denial-of-service condition exploitable from adjacent network position without authentication. The memory corruption flaw in the Windows WiFi driver stack can be triggered with passive user interaction, causing high availability impact to the vulnerable system and a residual low availability impact to subsequently connected systems. No public exploit code has been identified at time of analysis, and Intel has published advisory INTEL-SA-01422 addressing this issue.
Use-after-free in Vim's JSON channel parsing (versions 9.2.0511 through 9.2.0843) causes the socketserver process to crash when processing malformed JSON messages that straddle read-buffer boundaries. The stale pointer p in json_decode_item() is invalidated when channel_fill() frees the underlying buffer mid-parse; the error-reporting code then reads freed memory, producing a crash with no code-execution or data-exfiltration potential. No active exploitation is confirmed and no public exploit code has been identified; vendor-released patch v9.2.0844 resolves the flaw.
Heap out-of-bounds write in Tesseract OCR engine prior to 5.5.3 is triggered by a crafted LSTM .traineddata model file that causes a signed integer multiplication overflow in Convolve::DeSerialize, undersizing the forward-pass output buffer while write operations use the original unwrapped element count. Any application or user that loads an attacker-controlled model file is exposed to memory corruption that can lead to arbitrary code execution or process crash in the context of the OCR engine. No public exploit code has been identified at time of analysis, no CISA KEV listing exists, and a vendor-confirmed fix is available in Tesseract 5.5.3.
Out-of-bounds heap write in Zephyr RTOS's USB device-next CDC NCM class handler allows any physical USB host to corrupt the device's shared network buffer pool by issuing standard GET_NTB_PARAMETERS or GET_NTB_INPUT_SIZE control requests with a wLength field smaller than the response structure size. The overflow is bounded at up to 27 bytes and writes only fixed device constants, making its primary impact denial of service of the USB stack rather than arbitrary code execution. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; however, exploitation requires only physical USB access to a device built with the opt-in device_next stack and CDC NCM class.
Use-after-free in Zephyr RTOS kernel queue peek operations (z_impl_k_queue_peek_head and z_impl_k_queue_peek_tail in kernel/queue.c) allows a local low-privileged thread to obtain a dangling pointer to freed heap memory by winning a race against a concurrent k_queue_get call on a shared queue. Successful exploitation - requiring SMP or preemptive concurrency - can leak a stale heap pointer or crash the system when the returned dangling pointer is subsequently consumed as a live buffer in the net_buf, Bluetooth, USB, or networking subsystems. No public exploit exists and no active exploitation is confirmed; CVSS scores this at 3.6 (Low), accurately reflecting the narrow race window and local-only attack surface.
Heap out-of-bounds write in RadiAnt DICOM Viewer is triggered when processing JPEG-compressed pixel data embedded in a crafted DICOM file, potentially enabling arbitrary code execution on the victim's workstation. Reported to CISA ICS-CERT as a medical device advisory (ICSMA-26-218-01), the vulnerability requires no privileges and only passive user interaction - consistent with file-preview or file-open workflows common in clinical imaging environments. The provided CVSS 4.0 score of 5.3 rates impact as availability-only (VA:L), which conflicts materially with the described RCE potential; this discrepancy is significant and should be independently verified. No public exploit code or CISA KEV listing has been confirmed at time of analysis.
Use-after-free memory corruption in open62541's example client code allows a local low-privileged user to cause memory corruption with potential for denial of service or limited code execution. The vulnerability resides in the UA_Client_getRemoteDataTypes function within the examples/custom_datatype/client_types_custom.c file - notably example/sample code rather than the core library - at commit ca356b088ada7dee824d1b4acd07c1ff07ce242b. A publicly available proof-of-concept exploit exists, though the project closed the issue report citing improper disclosure channel, leaving no official patch or advisory. No confirmed active exploitation (CISA KEV absent), but the CVSS 4.0 E:P modifier reflects the published POC.
Use-after-free in Zephyr RTOS 4.4.0's Bluetooth ATT host layer (subsys/bluetooth/host/att.c) allows an adjacent unauthenticated peer to crash the Bluetooth host or potentially corrupt live memory by disconnecting while an ATT PDU is in-flight. The tx_meta_data_storage[] array retains a dangling att_chan pointer after L2CAP tears down and frees the channel slab slot, and the deferred att_tx_destroy_work_handler running on the system workqueue dereferences that freed pointer. No pairing or special privileges are required - a routine ATT connection is sufficient to reach the vulnerable code path. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Off-by-one memory corruption in popt's poptStuffArgs function allows a local low-privileged attacker to overwrite adjacent memory and potentially execute arbitrary code within any host application that unsafely processes the corrupted argument data. All supported Red Hat Enterprise Linux releases (6 through 10), Red Hat Hardened Images, and OpenShift Container Platform 4 ship the affected library. No public exploit code has been identified and no CISA KEV listing exists; exploitation requires high-complexity triggering conditions, making this a routine patch priority rather than an emergency response item.
Out-of-bounds write in the wifi subsystem of MediaTek MT6890, MT6990, and MT6988 chipsets enables a local denial of service, crashing the wifi component or device. Exploitation requires that the attacker has already obtained System-level privilege on the affected device - an extremely high bar that makes this a post-exploitation nuisance rather than an initial access vector. EPSS sits at 0.13% (3rd percentile), no public exploit code exists, and the vulnerability is not listed in the CISA KEV catalog, all consistent with the substantial privilege prerequisite.
Out-of-bounds write in the 'med' media processing component of specific MediaTek SoC chipsets (MT6890, MT6988, MT6990, MT2735, MT2737) enables a local attacker with standard user privileges to crash the device, causing a denial of service. The root cause is an incorrect bounds check (CWE-787) that allows a write past allocated buffer boundaries, corrupting memory. No public exploit is identified at time of analysis, and EPSS at 0.15% (4th percentile) combined with SSVC exploitation status of 'none' signals very low real-world exploitation probability.
Out-of-bounds write in MediaTek's HFRP component on the MT6993 chipset enables local privilege escalation beyond System-level access, confirmed via MediaTek's August 2026 security bulletin. The flaw stems from a missing bounds check (CWE-787), requiring an attacker who has already achieved System privilege to trigger further escalation - a post-compromise lateral movement primitive rather than an initial access vector. No public exploit code and no KEV listing have been identified; EPSS sits at the 3rd percentile, consistent with SSVC's 'exploitation: none' finding.
Out-of-bounds write in MediaTek's GeniZone Trusted Execution Environment (TEE) component enables local privilege escalation across 14 distinct MediaTek chipsets. An attacker who has already achieved System-level privilege on an affected Android device can exploit a missing bounds check to write outside intended memory boundaries within the secure enclave, gaining confidentiality and integrity access beyond what System privilege normally permits. No public exploit has been identified at time of analysis, and the EPSS score of 0.13% (3rd percentile) reflects low observed exploitation probability; however, the pre-existing System privilege prerequisite substantially narrows the realistic attack surface.
Out-of-bounds write in MediaTek's GenieZone hypervisor component enables local privilege escalation beyond System-level access on a wide range of MediaTek mobile chipsets. Exploitation is constrained to attackers who have already obtained System privileges, making this a secondary step in a multi-stage attack chain rather than an initial foothold technique. No public exploit code exists and EPSS of 0.13% (3rd percentile) confirms negligible real-world exploitation activity; no CISA KEV listing at time of analysis.
Heap buffer overflow in MediaTek's Audio Hardware Abstraction Layer (HAL) across six chipset families enables local denial of service on affected mobile and automotive platforms. A local user-level process can trigger an out-of-bounds write in the Audio HAL, crashing the audio subsystem with no user interaction required. No public exploit exists and EPSS sits at 0.15% (5th percentile), consistent with SSVC's 'none' exploitation status and the strictly local, availability-only impact profile.
Out-of-bounds write in the MediaTek display driver allows a local attacker who has already obtained System-level privilege to further escalate privileges on affected Android devices. The vulnerability stems from a missing bounds check (CWE-787) in display subsystem code across at least ten MediaTek chipsets, including MT8910, MT8188, MT8799, and MT6991 among others. No public exploit or active exploitation (CISA KEV) is identified at time of analysis; EPSS score of 0.14% (4th percentile) and SSVC exploitation rating of 'none' both confirm this remains an undemonstrated threat as of the August 2026 advisory.
Local denial of service in MediaTek's ccci (Cross Core Communication Interface) kernel driver affects MT6986, MT6988, and MT6813 chipsets through a missing bounds check that enables an out-of-bounds memory access. A local user-privileged attacker - such as a malicious Android application - can crash the kernel, causing device unavailability without requiring user interaction. No public exploit code exists and EPSS probability is 0.16% (6th percentile); SSVC exploitation status is confirmed 'none,' aligning all risk signals toward low immediate threat.
Local privilege escalation in MediaTek's display subsystem affects 17 chipset variants used in Android devices, allowing an attacker who has already obtained System-level privilege to exploit a missing bounds check (CWE-787) and write out of bounds in display memory, achieving high confidentiality and integrity impact. The CVSS vector (PR:H/AV:L) confirms this is not an initial-access vector - it is a post-compromise escalation step requiring pre-existing System privilege. No public exploit has been identified, EPSS stands at 0.14% (4th percentile), and the vulnerability is not listed in CISA KEV, consistent with SSVC's exploitation status of 'none.'
Local privilege escalation in the MediaTek display driver allows an attacker who already holds System-level privileges to further escalate via a use-after-free memory corruption condition, potentially achieving kernel-level access. Seventeen MediaTek SoC models used across Android devices are affected, disclosed in MediaTek's August 2026 security bulletin with Patch ID ALPS11019722. No public exploit code exists and EPSS at 0.14% (4th percentile) confirms negligible current exploitation probability; this vulnerability is not in the CISA KEV catalog.
Out-of-bounds write in MediaTek's Trusted Firmware-A (TFA) component allows a local attacker already holding System-level privilege to crash the device, causing a denial of service. Affected hardware includes MediaTek Dimensity and Helio chipsets MT6986D, MT6986, and MT6982VB. No public exploit code has been identified and CISA KEV does not list this vulnerability, consistent with its low EPSS score of 0.14% and SSVC exploitation status of none.
Out-of-bounds write in the MediaTek Download Agent (DA) firmware component across eight chipset families allows an attacker with physical device access to trigger a local denial of service by sending a crafted payload while the device is in DA mode. Affected chipsets span mobile SoCs (MT6880, MT6890, MT6990, MT6988, MT6986, MT6813) and modem/automotive chipsets (MT2735, MT2737), broadening the potential device footprint across Android smartphones and connected vehicle platforms. No public exploit code exists, EPSS sits at the 6th percentile (0.16%), SSVC confirms no known exploitation, and the physical access prerequisite fundamentally constrains real-world risk.
Local privilege escalation in MediaTek's apusys AI Processing Unit subsystem on MT8196 and MT8366 chipsets allows an attacker already holding System-level privileges to further escalate by exploiting a confused deputy flaw - likely realized through an out-of-bounds write (CWE-787) - achieving high confidentiality and integrity impact on the vulnerable system. Disclosed by MediaTek in their August 2026 Product Security Bulletin, a vendor patch is available under Patch ID AUTO00833804. No public exploit has been identified at time of analysis, and an EPSS of 0.14% at the 4th percentile reflects negligible probability of widespread exploitation.
Secure boot heap buffer overflow in MediaTek chipsets MT2737, MT6880, MT6890, and MT6990 enables local privilege escalation by an attacker with physical device access. The vulnerability exists at the pre-OS firmware layer, where a write beyond allocated heap boundaries can corrupt boot verification logic and permit execution of unsigned or attacker-controlled code. No active exploitation has been confirmed - the vulnerability is absent from CISA KEV, and the EPSS score of 0.16% (6th percentile) is consistent with the hard physical access prerequisite sharply limiting opportunistic exploitation.
Out-of-bounds write in the MediaTek HEVC video decoder enables further privilege escalation on devices running MT6761, MT8766, and MT8768 chipsets. The flaw, rooted in an integer overflow during HEVC bitstream processing, can be triggered without user interaction but only by an actor who already holds System-level privilege on the device. No public exploit code has been identified at time of analysis, and EPSS sits at 0.18% (8th percentile), consistent with SSVC's 'Exploitation: none' assessment - though SSVC rates Technical Impact as total, reflecting the severity of what a successful second-stage exploit could achieve.
Cross-buffer memory aliasing in msgpack-ruby prior to 1.8.2 allows same-process code to read or corrupt data belonging to a separate MessagePack::Buffer instance via a use-after-free in the rmem slab allocator. MessagePack::Buffer#clear returns a 4 KiB rmem page to the shared pool but leaves rmem_last, rmem_end, and rmem_owner pointing into the freed page; a subsequent write on the cleared buffer and a concurrent second Buffer allocation can claim the same physical page, creating a memory alias that exposes the second buffer's serialized bytes. A PoC is included in the vendor advisory (GHSA-4mrv-5p47-p938); no public exploit identified at time of analysis beyond that PoC, and the CVE is not in CISA KEV.
Use-after-free in Chrome's DataTransfer component on Windows exposes process memory to local attackers who can deliver a crafted HTML page to a victim. The flaw affects all Chrome versions on Windows prior to 151.0.7922.72 and results in high-confidence confidentiality loss with no integrity or availability impact. No public exploit code has been identified and EPSS sits at 0.11% (2nd percentile), consistent with CISA SSVC classifying exploitation as 'none' and technical impact as 'partial' - making this a low operational priority despite the High confidentiality CVSS sub-score.
Sandbox escape in Google Chrome's ANGLE graphics layer on Android enables an attacker who has already compromised the renderer process to break out of the Chrome sandbox via a crafted HTML page. Affected versions are all Chrome for Android releases prior to 151.0.7922.72. This is a second-stage exploit primitive requiring a prior renderer compromise; no public exploit code exists and SSVC reports exploitation as none, keeping real-world risk moderate despite the scope-change nature of the flaw.
Sandbox escape in Google Chrome for Android (prior to 151.0.7922.72) stems from a type confusion flaw (CWE-843) in the Tab component, enabling an attacker who has already compromised the renderer process to break out of Chrome's security sandbox via a crafted HTML page. This is a second-stage exploit primitive requiring renderer pre-compromise, reflected in the AC:H and S:C CVSS metrics. No active exploitation has been confirmed (not in CISA KEV), and EPSS sits at 0.20% (10th percentile), consistent with a chained, complex attack rather than opportunistic mass exploitation. Patch is available as Chrome 151.0.7922.72.
Use-after-free in the GPU process on macOS enables sandbox escape in Google Chrome versions prior to 151.0.7922.72, but only when an attacker has already achieved renderer process compromise. This is a second-stage exploit primitive - it extends an existing renderer compromise across the sandbox boundary into the GPU process, potentially allowing arbitrary code execution outside Chrome's sandbox on macOS. No public exploit code has been identified and EPSS sits at 0.21% (11th percentile), indicating low observed exploitation probability; however, sandbox escapes are a critical capability for attackers chaining browser exploit kits.
Use-after-free in the Bluetooth component of Google Chrome on Android prior to 151.0.7922.72 enables a sandbox escape for remote attackers who have already achieved renderer process compromise. Exploitation requires delivering a crafted HTML page to a victim user and successfully triggering a memory corruption condition in the Bluetooth subsystem, allowing code execution outside the renderer sandbox. No public exploit code has been identified at time of analysis, and EPSS at 0.21% (11th percentile) indicates low observed exploitation probability; no CISA KEV listing is present.
Buffer overrun in the Apache Traffic Server multiplexer plugin's chunk-decode logic allows network-adjacent attackers who can influence upstream origin responses to cause denial of service across versions 8.0.0 through 10.1.3. The flaw is classified as CWE-787 (Out-of-bounds Write) and is constrained to availability impact only - no code execution or data exposure is indicated. No public exploit or CISA KEV listing has been identified, and the CVSS 3.7 Low score reflects meaningful real-world limitations, primarily the high attack complexity imposed by the upstream-input dependency.
Use-after-free in the sqlite3 Ruby gem (published as both sqlite3-ruby and sqlite3) versions 2.1.0 through 2.9.4 lets an aggregate function be invoked through a still-open prepared statement after its Database object has been explicitly closed, producing an invalid memory read and a segmentation fault that crashes the Ruby process. Exploitation requires an in-process API-misuse pattern in the host application itself - local, high-complexity, low-privileged per the assessed CVSS:3.1 vector (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L) - with no remote or network vector and no attacker-supplied input. No public exploit identified at time of analysis (EPSS 0.11%, CISA SSVC exploitation: none, Automatable: no); the maintainers classify it as Low severity, describing a reliably reproducible crash after garbage collection rather than a proven denial-of-service or code-execution primitive.
A use-after-free vulnerability in the sqlite3-ruby gem allows an attacker to crash the Ruby process by defining a custom SQLite function with the same name but a different number of arguments or text encoding, leading to an invalid memory read and segmentation fault. The issue affects versions prior to 2.9.5 and was assessed as low severity by the maintainers due to the specific code pattern required for exploitation.
Memory corruption in Xen allows guest VMs with Populated on Demand (PoD) enabled to cause denial of service by attempting to reclaim non-guest memory pages, corrupting hypervisor memory management state. No public exploit identified and SSVC indicates no current exploitation, but the flaw is automatable with partial technical impact.
Denial-of-service via out-of-bounds write in Apple CoreAudio when processing malicious audio streams. Affected iOS, iPadOS, macOS, tvOS, watchOS, and visionOS versions are vulnerable. No known active exploitation or public exploit code exists at time of analysis, and EPSS probability is low (0.17%).

Out-of-bounds read in Apple macOS allows a local app to access sensitive user data. The vulnerability (CWE-787) has been patched in macOS Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6. Exploitation requires user interaction (opening a malicious app or file), and no public exploits are known to be in the wild.
Unexpected Safari crash via use-after-free when processing maliciously crafted web content affects Safari 26.6 and earlier on all Apple platforms. This denial-of-service condition requires user interaction to open a malicious webpage; no public exploit identified and EPSS probability is low (0.14%).
Denial of service in Apple operating systems via out-of-bounds write allows a local app to cause unexpected system termination. Affected versions include iOS/iPadOS, macOS Tahoe, tvOS, visionOS, and watchOS prior to 26.6. No active exploitation has been reported, EPSS risk is low at 0.16%, and no public exploit code identified at time of analysis.
Denial of service in SQLite 3.41 due to a use-after-free in the JSON extraction function. A local unauthenticated attacker can trigger a crash by supplying a malicious JSON input, causing the host application to terminate. No active exploitation has been confirmed in the wild, but public exploit proof-of-concept may exist.
A heap buffer over-write in ImageMagick's fx operation can be triggered via a crafted argument when processing images with the Magick.NET library, leading to a denial of service. Affected versions of the Magick.NET NuGet package (before 14.15.0) are confirmed vulnerable; no active exploitation or public proof-of-concept has been identified. The vulnerability has a medium CVSS score (5.0) with local attack vector and user interaction required.
Memory corruption via use-after-free in NLnet Labs Unbound 1.25.0-1.25.1 can cause a DNS resolver crash under specific, non-default configurations when the server is under load. The flaw originates from a regression introduced in a fix enabling 'respip' and 'dns64' module interoperability: subqueries receive a shallow copy of the active view name, and if the parent query is evicted (jostled) before the subquery completes, the dangling reference causes memory corruption. No public exploit code exists and no confirmed active exploitation (CISA KEV) has been identified; the vendor explicitly describes crash likelihood as low due to dependence on memory layout and allocator behavior.
Use-after-free in NLnet Labs Unbound 1.15.0 through 1.25.1 crashes the DNS daemon via a dangling pointer to a freed TLS server name string in the DNS-over-TLS forwarding path. A remote attacker with knowledge of the target resolver's configuration can trigger the crash by sustaining query pressure against the configured DoT zone while inducing a transient upstream connection failure, causing denial of service. No public exploit code exists and this vulnerability has not been confirmed as actively exploited, but the network-accessible attack surface (PR:N) makes it relevant to operators running internet-facing recursive resolvers with DoT forwarding.
Heap use-after-free in the SyncTeX parser shipped with TeX Live and embedded by GNOME Evince allows crash or potential arbitrary code execution when a user opens a malformed .synctex or .synctex.gz file. The flaw stems from a NULL parent pointer condition in _synctex_post_process_ref() that bypasses node detachment, causing recursive freeing of live tree nodes and leaving dangling pointers later accessed during document parsing. Exploitation requires local file access and active user interaction (UI:A per CVSS 4.0), no public exploit has been confirmed, but a detailed researcher blog post by the discoverer (Fatih Çelik) is publicly available and the RCE tag suggests demonstrated impact potential.
Out-of-bounds memory corruption in kronosnet's packet reassembly engine (versions ≤ 1.34) enables a remote, unauthenticated network attacker to crash the kronosnet process or cause heap corruption by transmitting malformed fragmented packets carrying invalid sequence numbers. Affected deployments span Red Hat Enterprise Linux 8, 9, and 10, and Red Hat OpenShift Container Platform 4, making this relevant to HA clustering infrastructure that depends on kronosnet for inter-node communication via Corosync or Pacemaker. No public exploit code and no active exploitation have been identified at time of analysis, though the network-accessible, no-privilege-required attack path elevates operational risk for clustered environments despite the AC:H complexity rating.
Out-of-bounds write in davenardella snap7 up to version 1.4.3 allows network-authenticated attackers to corrupt memory by supplying a crafted PDULength value during S7 protocol negotiation. The vulnerable function TSnap7Peer::NegotiatePDULength in src/core/s7_peer.cpp fails to enforce bounds on the PDULength argument, enabling writes beyond the allocated buffer boundary. A public proof-of-concept exploit is available on GitHub (issue #17), and the CVSS 4.0 E:P modifier confirms this - elevating practical risk above the medium base score, particularly in OT/ICS deployments where snap7 is commonly used to interface with Siemens S7 PLCs.
Out-of-bounds write in Bouncy Castle BC-LTS bcprov-lts8on affects ARM deployments running versions 2.73.0 through 2.73.12.0, with high confidentiality impact if successfully exploited. The flaw resides in ARM-specific native C implementations of SHA3 and SHAKE algorithms and is only triggered when an application accepts memoable SHA3/SHAKE cryptographic states from potentially untrusted external sources. No public exploit code exists and no active exploitation has been confirmed at time of analysis; the CVSS 4.0 score of 1.7 reflects the very narrow exploitation conditions required to reach this code path.
YAML::Syck before version 1.47 crashes the Perl interpreter when parsing a YAML document that redefines an anchor name, due to a use-after-free and double-free in the bundled libsyck C library. Any caller invoking Load() or LoadFile() on attacker-controlled YAML - a common pattern in Perl web frameworks and data-pipeline tooling - is exposed to a denial-of-service condition that aborts the interpreter process. No public exploit beyond the CPANSec-confirmed 7-byte trigger document exists and no CISA KEV listing is present, but the trivially short trigger makes reliable reproduction straightforward.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local attacker with high OS-level privileges to execute arbitrary code in System Management Mode (SMM) - a CPU execution context operating below the operating system and hypervisor with access to all system memory. Successful exploitation allows persistent firmware-level implants that survive OS reinstallation and defeat Secure Boot and standard endpoint detection tools. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, SMM code execution represents one of the highest-impact firmware attack primitives available to an advanced threat actor.
Out-of-bounds write in Lenovo BIOS firmware across dozens of consumer and gaming laptop models enables a local privileged attacker to corrupt power management settings within System Management Mode, a CPU execution context operating below the OS kernel at Ring -2. Successful exploitation could allow persistent firmware-level tampering that survives OS reinstalls and reboots. No public exploit has been identified at time of analysis, and exploitation requires pre-existing high OS-level privileges, substantially limiting real-world risk to post-compromise scenarios.
Use-after-free in ESET's Linux security product kernel components enables a local high-privileged attacker to trigger a kernel panic, causing a complete system crash and denial of service. Both ESET Endpoint Antivirus for Linux and ESET Server Security for Linux are affected across unspecified versions, per ESET's own customer advisory. No public exploit code has been identified and CISA has not added this to the Known Exploited Vulnerabilities catalog; however, server-deployed AV with kernel-level hooks makes the DoS impact operationally significant in production environments.
Heap overflow in Absolute Security Secure Access client certificate parsing causes a local denial of service. Versions prior to 14.55 are affected. An attacker who already holds local administrator privileges on a managed endpoint can trigger the overflow to crash the Secure Access client, effectively disabling it on that machine. No public exploit code has been identified, and this vulnerability is not listed in the CISA KEV catalog.
Use-after-free in ImageMagick's FreeType integration path allows remote denial of service against image processing pipelines using vulnerable 6.x or 7.x releases. When FreeType initialization fails during an image processing operation, the affected code path neglects to exit cleanly and continues referencing already-freed memory, causing process corruption or crash. No public exploit identified at time of analysis; the CVSS 4.0 score of 6.3 with AC:H and AT:P reflects meaningful preconditions required to trigger the failure path.
Denial of service in BusyBox 1.38.0 arises from a use-after-free in the awk_sub() routine of the AWK applet (editors/awk.c), allowing an attacker who can supply a crafted AWK script to crash the busybox awk process. The flaw is a memory-corruption bug (CWE-416) with availability-only impact and no confidentiality or integrity consequences. There is no public exploit identified at time of analysis, it is not listed in CISA KEV, and its EPSS score is low (0.14%, 4th percentile).
Type confusion (CWE-843) in Microsoft SQL Server 2025 enables authenticated, low-privileged network attackers to disclose sensitive server-side information. The CVSS vector (AV:N/PR:L/C:H) confirms that any authorized database user - regardless of their data access permissions - can potentially trigger the flaw remotely with no user interaction required. No public exploit code or CISA KEV listing exists at time of analysis, but the high confidentiality impact and low access complexity make patching a meaningful priority for organizations running SQL Server 2025.
Use-after-free in the Windows Virtual Filtering Platform (VFP) enables authenticated network attackers to crash affected Windows endpoints and servers, resulting in a denial-of-service condition. The vulnerability spans a broad range of supported Windows 10, Windows 11, and Windows Server releases through 2025, making patch prioritization important despite the medium CVSS score. No public exploit code or active exploitation has been identified at time of analysis, and SSVC classifies this as not automatable with partial technical impact.
Privilege escalation via physical attack in the Windows Cloud Files Mini Filter Driver (cldflt.sys) affects all major Windows 10, Windows 11, and Windows Server releases through 2025. The use-after-free memory corruption flaw (CWE-416) in the kernel-mode driver allows an attacker with physical access to the device to escalate privileges to SYSTEM level, achieving full confidentiality, integrity, and availability compromise. No public exploit code has been identified and CISA has not listed this in KEV, but the SSVC assessment notes total technical impact - the physical access requirement is the primary limiting factor, not the vulnerability's severity once that barrier is cleared.
Type confusion in the Windows Composite Image File System (CimFS) kernel driver enables local, low-privileged authenticated users to disclose protected memory contents on widely-deployed Windows 10, Windows 11, and Windows Server platforms. The flaw (CWE-843) causes the driver to access a kernel resource via an incompatible type, resulting in unintended memory reads with high confidentiality impact. No public exploit or active exploitation has been confirmed - SSVC lists exploitation as 'none,' EPSS stands at 0.29% (21st percentile), and the vulnerability is absent from the CISA KEV catalog - placing real-world risk in the lower-medium tier despite the C:H CVSS sub-score.
Privilege escalation via use-after-free in the Windows USB Print Driver affects Windows 11 (versions 24H2, 25H2, 26H1) and Windows Server 2025, requiring physical access to exploit. An attacker with hands-on access to a target machine can trigger a memory corruption condition through the USB print subsystem to achieve full local privilege escalation - High confidentiality, integrity, and availability impact per CVSS. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Use-after-free memory corruption in gawk's do_getline_redir() routine within io.c allows a local attacker to crash the gawk process, causing a denial of service. All gawk versions 5.4.0 and below are affected, as confirmed by CERT-PL and an upstream patch commit. No active exploitation has been identified (not in CISA KEV), and the impact is confined to availability - no confidentiality or integrity effects have been demonstrated.
Out-of-bounds stack write in Zephyr's nRF70 Wi-Fi driver exposes embedded systems to memory corruption when the nRF70 co-processor returns a power-save event with more than eight TWT flow entries. The vulnerable function `nrf_wifi_event_proc_get_power_save_info()` blindly copies co-processor-supplied TWT entries into a fixed 8-element stack array without validating `num_twt_flows` against `WIFI_MAX_TWT_FLOWS`, enabling heap/stack corruption of approximately 40 bytes per excess entry. No public exploit code exists and the flaw is not listed in CISA KEV, but the adjacent-network attack vector and the indirect over-the-air influence path via a rogue AP manipulating TWT sessions make this a meaningful risk in Wi-Fi 6 (802.11ax) deployment environments running Zephyr with `CONFIG_NRF70_STA_MODE`.
