Denial of service in GPAC 26.08-DEV can result from a use-after-free when a local user opens a crafted BIFS/MPEG-4 scene file containing malicious proto-library links. Exploitation requires local processing of an attacker-supplied file and the realistic outcome is an application crash with availability impact only; there is no demonstrated confidentiality or integrity impact and no demonstrated code execution. Publicly available exploit code exists, but the issue is low severity (CVSS 1.9 in the supplied 4.0 vector) and the independent assessment notes the PR:L requirement is questionable, viewing the attack as local file parsing with user interaction. The vulnerability is fixed in GPAC abi-16.24 via commit e34f4ba349d55cd1849f0bcf4cf46552732e2db7.
Local use-after-free in GPAC's scenegraph command handling (gf_sg_command_apply / gf_node_deactivate_ex) lets an attacker crash MP4Box and other GPAC-based tools when a victim opens or converts a crafted LASeR/SVG scene, or an MP4 that embeds one. The vector is local and requires the victim to process the malicious media, and the assessed impact is availability only (process crash; C:N/I:N/A:L) with no confidentiality or integrity loss and no demonstrated code execution. Publicly available exploit code exists (a PoC archive was published alongside the VulDB report), the issue is fixed by the GPAC abi-16.24 release, and it is explicitly distinct from CVE-2026-90827.
Heap use-after-free in the HDF5 library (The HDF Group, all versions before 2.3.0) is triggered when an application such as h5dump reads a dataset whose compound datatype contains floating-point members, allowing a crafted .h5 file to crash the parsing process and, depending on heap layout and allocator behaviour, potentially corrupt memory further. Exploitation requires the victim to open a malicious file locally (local vector, mandatory user interaction, no authentication needed), so it is not remotely reachable on its own. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV; the vendor's own CVSS 4.0 base of 4.6 aligns with the independent assessment that the reliably demonstrated impact is a crash rather than proven code execution.
Denial of service in ISC BIND 9 recursive resolvers: an attacker who controls (or compromises) an authoritative server for a DNSSEC-signed zone can cause `named` to abort after it encounters a use-after-free when processing a specific crafted sequence of answers. The attacker must first induce the victim resolver to issue multiple queries for that attacker-hosted zone, and the malicious responses must then arrive in a particular order and timing to trip the race, which is why this is rated high complexity (AC:H) despite being remote and unauthenticated (PR:N, no user interaction). Impact is availability-only (C:N/I:N/A:H), and exploitation is limited to `named` running as a recursive resolver on the listed versions; only 9.20.29 and later are fixed, and no public exploit code or confirmed active exploitation was identified at time of analysis.
Denial of service in NLnet Labs Unbound 1.12.0 through 1.26.0 arises from a use-after-free in the DNS-over-HTTPS (DoH) code path, reachable only in builds compiled with --with-libnghttp2 when failure conditions such as an RPZ drop action or heavy-traffic stream jostling occur. A remote, unauthenticated attacker can trigger the flaw with a single DoH connection and appropriate traffic, causing memory corruption that, under a hardened allocator, results in controlled termination of the Unbound process. No public exploit code has been identified at time of analysis; the impact is confined to availability (CVSS 5.9, C:N/I:N/A:H) with no confidentiality or integrity effect.
Unbound versions 1.22.0 through 1.26.1 built with DNS-over-QUIC support (--with-libngtcp2) can be driven to an abnormal exit by an unauthenticated remote attacker who manipulates QUIC stream state. The attacker sends a DoQ query, withholds ACKs, issues RESET_STREAM to free the per-stream output buffer, then waits for a PTO timeout so ngtcp2 re-encodes a STREAM frame from the freed memory; a spray of roughly 20 such queries forces the daemon down. Default builds compiled without QUIC support are not affected, and exploitation also requires precise timing against the QUIC state machine, making this a moderate, configuration-gated availability threat rather than a top-tier priority. No public exploit code and no confirmed active exploitation were identified at time of analysis, and the authoritative assessment rates it AV:N/AC:H/PR:N/UI:N/S:U with low confidentiality and high availability impact, so the practical outcome is denial of service against the resolver rather than broad data compromise.
Use-after-free in Chrome's Skia graphics library allows an attacker who has already compromised the renderer process to read cross-origin data after a victim opens a crafted HTML page in Chrome versions prior to 153.0.8010.47. Chromium rates the bug High severity because it can breach the same-origin boundary, even though the CVSS base score is only 3.1 (confidentiality-limited, no integrity or availability impact). No public exploit code or CISA KEV entry is associated with this CVE at time of analysis, and the attack is not automatable per CISA's SSVC assessment.
A use-after-free in the ARM SMMU v3 driver (arm-smmu-v3.c) of the Android kernel lets a local attacker who already holds System-level execution privileges corrupt kernel memory and escalate to full kernel/System privilege. The flaw is a logic error in one of several driver functions that leaves a freed object reachable, and no user interaction is needed once the attacker has code running at that privilege level. It is ranked CVSS 6.7 (AV:L/PR:H), there is no indication of active exploitation or public exploit code, and Google published a fix in the September 2026 Pixel security bulletin.
Use-after-free in FreeRDP's smartcard RDPDR device handler (before 3.31.0) allows a malicious or compromised RDP server to free a registered device pointer while the device manager still holds a reference, producing a dangling pointer that can crash the client or potentially be leveraged for code execution in the victim's session. The flaw is only reachable when a client with smartcard redirection enabled connects to an attacker-controlled RDP endpoint and the attacker can force a worker-thread creation failure during channel setup — a narrow, non-deterministic window reflected in the low CVSS 4.0 score of 2.3 (AV:N/AC:H/AT:P/PR:N/UI:P, availability-only impact). A vendor patch is available in FreeRDP 3.31.0; no public exploit code and no CISA KEV listing were identified at time of analysis.
Use-after-free in GPAC's scenegraph node handling allows a remote attacker to trigger memory corruption by delivering a crafted media file that is processed by the affected application. The vulnerability exists in `gf_node_get_name_and_id()` in `scenegraph/base_scenegraph.c`, where a node pointer could be dereferenced after being freed due to missing null/reference-count guards in the BIFS decoder's command assignment path. Exploitation requires user interaction (opening a malicious file), a publicly available proof-of-concept exists (poc_16_bt.zip), and no confirmed active exploitation is recorded in CISA KEV.
Use-after-free in GPAC's LASeR scene graph command processing subsystem allows remote attackers to corrupt heap memory by supplying a crafted media file, potentially leading to process crash or code execution. Affected are GPAC builds up to commit f1219cde; the flaw stems from direct node-pointer assignment without proper reference counting in the LASeR decoder and scene graph command application paths. A public proof-of-concept exploit is confirmed available; vendor-released patch exists at commit e34f4ba and release abi-16.24.
Use-after-free in zstd-jni's Dictionary Sharing component allows remote attackers to corrupt native heap memory through the ZstdCompressCtx.loadDict() and ZstdDecompressCtx.loadDict() APIs in versions up to 1.5.7-13. The defect is a logic inversion in shared-lock accounting: the code releases the reference count on the incoming dictionary parameter rather than on the previously held dictionary reference, causing the old native buffer to remain referenced after it can be freed by another thread. A public proof-of-concept exists via GitHub issue #404, and vendor released a confirmed fix in version 1.5.7-14.
A use-after-free memory-management flaw affects Apple's operating system family prior to the 26.6 releases — iOS and iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6 and watchOS 26.6 — and allows a locally installed app to trigger unexpected system termination (a denial-of-service condition). The vulnerability is rated CVSS 5.5 with a local attack vector, low complexity and low privileges required, but no confidentiality or integrity impact; EPSS is only 0.19 percent and there is no CISA KEV listing and no publicly available exploit code identified at time of analysis. Apple has shipped fixes in all four platform advisories, so the practical risk is concentrated on unpatched devices rather than on active exploitation.
A use-after-free (CWE-416) in Apple's memory management code allows a locally running application on iOS, iPadOS, macOS, tvOS, visionOS and watchOS to crash the affected system, producing an unexpected termination or reboot. The flaw affects all platforms before the fixed releases (iOS/iPadOS 26.7 and 27, macOS Sequoia 15.8, macOS Tahoe 26.7, macOS Golden Gate 27, tvOS 27, visionOS 27, watchOS 27) and rates CVSS 5.5 (AV:L/PR:L/UI:N, availability-only impact). No public exploit code or active exploitation has been identified, and EPSS is low at 0.21% (11th percentile), so this is a patched, availability-only issue rather than an urgent remote-code-execution threat.
A use-after-free in macOS memory management allows a locally running application to crash the operating system, resulting in unexpected termination and loss of unsaved work. The flaw affects macOS Tahoe before 26.6, macOS Sequoia before 15.7.8, and macOS Sonoma before 14.8.8, with exploitation requiring only low privileges (CVSS PR:L) and no additional user interaction. Apple has released fixes (patch available per vendor advisories), and although EPSS is very low at 0.19% (9th percentile) with no CISA KEV listing, no public exploit code identified at time of analysis, the flaw is a memory-safety bug that carries inherent risk of escalation beyond a simple denial of service.
A use-after-free memory management flaw in Apple iOS and iPadOS allows a locally installed application to crash the system, causing unexpected device termination (denial of service). All versions prior to iOS 27 / iPadOS 27 are affected per the vendor CPE wildcard and ENISA EUVD version range (0 < 27). Apple addressed the issue with improved memory management in iOS 27 and iPadOS 27; no public exploit code has been identified and the EPSS probability is very low (0.17%, 7th percentile), so this is primarily a stability/patch-hygiene issue rather than an active exploitation threat.
Unexpected system termination can be triggered on Apple devices by a locally executed app that exploits a use-after-free memory corruption in shared system code, which Apple addressed through improved memory management. The flaw affects essentially every current Apple OS branch below the fixed releases — iOS/iPadOS 26.6+, macOS 15.8/26.6+/27, tvOS 26.6+/27, visionOS 26.6+/27 and watchOS 26.6+/27 — with CVSS 5.5 reflecting an availability-only impact and a local attack vector. EPSS is low (0.24%, 16th percentile), no public exploit code has been identified, and there is no CISA KEV entry, so this is a routine patch-cycle item rather than an urgent threat.
A use-after-free (CWE-416) in the Apple macOS SMB client allows a maliciously crafted SMB network share to crash the operating system, causing system termination. Exploitation requires the user to mount the attacker-controlled share (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, base 6.5), so impact is limited to denial of service with no confidentiality or integrity loss. Apple has released fixes in macOS Golden Gate 27, macOS Sequoia 15.8, and macOS Tahoe 26.7; there is no CISA KEV listing and no public exploit code identified, and EPSS is low at 0.17% (6th percentile).
A use-after-free memory-management flaw in Apple's operating systems allows a locally installed application to crash the system, causing unexpected termination (denial of service) on affected iPhone, iPad, Mac, and Apple Vision Pro devices. Apple addressed the issue across iOS 26.7/iPadOS 26.7, iOS 27/iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, and visionOS 27. There is no evidence of active exploitation: CISA KEV does not list the CVE, SSVC records exploitation as 'none' and automatable as 'no', EPSS is a low 0.18% (7th percentile), and no public exploit code has been identified at the time of analysis.
A use-after-free write in the Zephyr RTOS ITE IT82xx2 USB device-controller driver (drivers/usb/udc/udc_it82xx2.c) affects Zephyr 4.0.0 through 4.4.1 and allows a malicious USB host to create a kernel heap-corruption primitive on the device side. When a multi-packet OUT transfer is received on a non-control endpoint, the driver re-arms the endpoint to keep filling the same net_buf while simultaneously handing that buffer to the upper USB device stack, which may free and recycle it while DMA continues; the completing packet is also submitted a second time, corrupting the event slist and causing a double net_buf_unref(). Exploitation is physical (USB attach) with no authentication or user interaction required, giving a reliable denial of service and plausible adjacent-pool memory corruption; no public exploit code or CISA KEV listing was identified for this CVE at time of analysis.
A use-after-free and double-free race in Zephyr's TLS socket session cache lets a malicious or compromised TLS peer corrupt the mbedTLS heap and crash an affected device. The flaw is reachable only by applications that explicitly enable the TLS_SESSION_CACHE socket option (off by default) and run concurrent TLS client connections from multiple threads, since the process-global client_cache defaults to a single shared slot. A vendor fix exists in commit 7f9d8ee (shipping in Zephyr 4.4.2 per the EUVD version range), and no public exploit code or active exploitation has been identified.
A use-after-free in GPAC's scene-graph handling (gf_sg_script_load path) lets a crafted MP4/VRML scene file corrupt memory when processed by MP4Box or any application embedding libgpac. Publicly available exploit code exists and the flaw is remotely deliverable, though exploitation requires the victim or an ingestion pipeline to actually open the malicious media file (UI:P). A vendor fix is available in release abi-16.23 / commit 9eb40df4448b88d6a6ce3454657c06f47eff0b24, and the CVSS 4.0 base score is only 2.1 because confidentiality, integrity and availability impacts are all rated Low.
Use-after-free
Use-after-free in GPAC's `gf_node_unregister` function (scenegraph/base_scenegraph.c) allows an attacker to cause a crash or limited memory corruption by supplying a crafted MP4, BT, or XMT scene file. The vulnerability arises from improper cleanup ordering of proto field default node values during scene graph teardown, with additional related issues in the BT and XMT scene loaders. A public proof-of-concept exploit exists (GitHub issue #3801 and dedicated write-up), though the CVSS 4.0 score of 2.1 and all-Low impact metrics indicate reliable code execution is unlikely - DoS via crash is the primary realistic outcome. No CISA KEV listing exists.
Use-after-free in Open5GS AMF component versions 2.0.x through 2.7.x allows network-reachable attackers to corrupt memory in the Access and Mobility Management Function process by triggering the old AMF discovery fallback handler with a crafted interaction. The root cause is premature deallocation of the SBI transaction structure (`ogs_sbi_xact_remove`) before the `discovery_option` argument derived from that structure is fully consumed; the fix relocates the free call past all dependent uses. No public exploit code has been identified; an upstream patch commit is available.
Use-after-free in GPAC's scene graph management allows remote attackers to cause memory corruption via a crafted multimedia scene file. The flaw exists in `gf_node_changed_internal` within `base_scenegraph.c` and is triggered when GPAC's BT/XMT scene loaders fail to properly track node lifecycle, leaving dangling references to freed nodes in `def_nodes` lists and proto field structures. A public proof-of-concept exploit has been disclosed and the vendor has released a fix in tag abi-16.23. No confirmed active exploitation (KEV) is recorded at time of analysis.
Use-After-Free in the Samsung Exynos DRM HDR kernel driver causes a kernel crash on devices running Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600 SoCs. The defect lies in the error-handling path of the HDR driver: when a vmap() call fails, cleanup does not properly invalidate the freed mapping, leaving a dangling reference that is subsequently dereferenced, crashing the kernel. The CVSS vector (AV:L/AC:H/PR:L) indicates a local low-privileged attacker can trigger this under specific error conditions, crossing into kernel scope (S:C). No public exploit code or active exploitation has been identified at time of analysis.
Use-after-free in GPAC's MP4Box multimedia tool (all versions through commit f1219cde) allows a local low-privileged attacker to corrupt heap memory via the gf_list_count function in utils/list.c, resulting in application crashes and potentially limited code execution within the process. The fix released in abi-16.23 (commit 49dee5cad329) addresses multiple interrelated UAF and null-dereference conditions across the scenegraph manager, BIFS memory decoder, and AV1 reframer subsystems. A public proof-of-concept exploit exists; no active exploitation has been confirmed via CISA KEV.
Use-after-free in Suricata 8.0.0-8.0.4 causes an engine crash when a malicious detection rule chains decompress transforms (gunzip or zlib_deflate with max-size exceeding 4096) after another transform, allowing the pipeline to read from a freed inspection buffer during subsequent network traffic processing. The net effect is a reliable denial-of-service: once the offending rule is loaded, any matching network traffic will crash the Suricata process regardless of traffic content. No public exploit or active KEV listing exists at time of analysis. Vendor-released patch is available in version 8.0.5.
Use-after-free in Suricata's inspection-buffer helper crashes the IDS/IPS engine, yielding a network-exploitable denial-of-service against any deployment running rules that chain the `dotprefix` transform after another transform. Affected versions prior to 7.0.16 (stable) and 8.0.5 include all prior 7.x and 8.x releases. No public exploit code and no CISA KEV listing have been identified; exploitation requires an attacker to know or guess that the target's ruleset matches the vulnerable pattern, and then craft traffic to trigger the reallocation path.
Heap use-after-free in DaveGamble cJSON's cJSONUtils_MergePatch function (cJSON_Utils.c) affects all versions through 1.7.19 when the patch argument is a subtree of the target object. The function deletes the target before duplicating the patch, freeing the patch memory and causing a subsequent read of freed heap - confirmed by an AddressSanitizer-triggering test case in upstream fix PR #1065. A public exploit exists (GitHub issue #1060) and can lead to crash, potential memory disclosure, or memory corruption in any application that passes attacker-influenced JSON through this specific merge-patch call pattern.
A crafted series of RTSP and HTTP requests sent to LIVE555 Streaming Media 2026.02.26 triggers a use-after-free in SocketDescriptor::tcpReadHandler1 (liveMedia/RTPInterface.cpp), crashing the media server and terminating all active streams. The flaw is reachable over the network without credentials, and because LIVE555 is embedded in IP cameras, streaming appliances and media servers, one crash can disrupt many downstream viewers at once. No public exploit code and no CISA KEV entry were identified at time of analysis, EPSS places exploitation probability at roughly 0.15% (5th percentile), and the supplied references do not state an exact fixed build number.
Use-after-free in Chrome's V8 JavaScript engine enables an attacker with a pre-compromised renderer process to read arbitrary memory within the sandbox boundaries via a crafted HTML page. Affected versions are Chrome prior to 153.0.8010.36 on all desktop platforms. Unlike most Chrome UAF findings that achieve sandbox escape, this vulnerability is constrained to intra-sandbox memory disclosure (C:L, S:U), making it a stepping-stone primitive rather than a standalone critical exploit. No public exploit code or CISA KEV listing exists at time of analysis.
Use-after-free in Adobe Acrobat Reader and Acrobat exposes sensitive heap memory contents when a victim opens a specially crafted PDF file. The vulnerability affects Acrobat and Acrobat Reader up to version 26.002.21900 and Acrobat 2024 up to 24.001.30383, with confidentiality impact rated High by Adobe PSIRT. No public exploit code has been identified at time of analysis, and exploitation requires the victim to open a malicious file.
Use After Free (CWE-416) in Adobe Acrobat and Acrobat Reader permits sensitive memory disclosure when a victim opens a maliciously crafted document. Affected versions span Acrobat and Acrobat Reader ≤26.002.21900 and Acrobat 2024 ≤24.001.30383. The memory-corruption primitive exposes heap contents - potentially including credentials, key material, or in-process data - but the CVSS vector confirms no integrity or availability impact, making this a pure information-disclosure issue. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Use-after-free in Windows Distributed File System (DFS) enables an authenticated network attacker to crash the DFS service, resulting in denial of file-sharing access across affected Windows client and server versions. The CVSS vector (AV:N/AC:H/PR:L) confirms network reachability but constrains exploitation to low-privilege authenticated accounts under high-complexity conditions. Microsoft has released patches covering the full affected range from Windows 10 1607 through Windows Server 2025; no public exploit code or active exploitation has been identified at time of analysis.
Use-after-free (CWE-416) in Microsoft Office Word enables a locally authenticated attacker to disclose sensitive memory contents. Exploitation requires only low-privileged local access with no user interaction, yielding high confidentiality impact per the CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N vector. No public exploit or active exploitation has been identified at time of analysis, and a vendor-released patch is available through Microsoft's update mechanism.
Use-after-free in MongoDB Server's cursor management component allows an authenticated remote attacker to crash the mongod server process, causing a denial of service. Under specific timing conditions during cursor lifecycle events, a stale pointer to a freed resource is retained and later dereferenced during cursor cleanup, producing undefined behavior and a process crash. Affected branches are MongoDB 7.0.x before 7.0.41, 8.0.x before 8.0.30, and 8.3.x before 8.3.9; vendor-patched releases are available, and no public exploit code is identified at time of analysis.
Heap use-after-free in MongoDB Server's text index query parser allows authenticated users with readWrite privileges to crash the server process through deliberate concurrent operations. By combining upsert retry text-search queries with concurrent index lifecycle operations (create/drop) on the same collection, an attacker can trigger a race window where a raw pointer to freed text index metadata structures is dereferenced, aborting the mongod process and causing denial of service for all connected clients. No public exploit has been identified; vendor patches are available for all three affected release lines (7.0.x, 8.0.x, 8.3.x).
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture Kernel Drivers allows a local non-privileged process to access already-freed GPU memory through otherwise-valid GPU memory processing operations. The flaw spans a wide range of driver releases across all three GPU families - covering most modern Arm Mali GPU generations deployed in Android SoCs from r41p0 onward. No public exploit code or active exploitation has been identified; EPSS sits at 0.14% (4th percentile), and the vulnerability is not listed in the CISA KEV catalog.
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture kernel drivers allows an unprivileged local process to access already freed kernel memory, leaking limited sensitive data. The flaw is triggered through valid GPU memory processing operations, requiring no special privileges beyond local code execution - a realistic threat on mobile devices running affected Mali GPU firmware. With EPSS at 0.14% and no public exploit or KEV listing, active exploitation is not currently observed, but the breadth of affected versions across three GPU families and many Android SoC generations elevates overall exposure.
Use-after-free memory access in Arm's Valhall and 5th Gen GPU Architecture userspace drivers allows a non-privileged local process - including browser-hosted WebGL or WebGPU workloads - to read and write already-freed GPU memory regions, yielding limited confidentiality and integrity compromise. Arm reported this issue internally; no active exploitation has been identified. The wide deployment of Arm Mali GPU hardware in mobile and embedded SoCs makes the affected driver versions relevant across a large device population, though the limited CVSS impact scores constrain severity.
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU kernel drivers allows a local unprivileged process to access already-freed GPU memory through valid GPU memory processing operations, resulting in limited confidentiality and integrity impact against the kernel driver. The flaw spans a wide range of driver versions across all three GPU architectures, affecting the enormous ecosystem of Android and embedded devices powered by Arm Mali GPUs. No public exploit or active exploitation has been identified; SSVC rates technical impact as partial and exploitation as none at time of analysis.
Heap-use-after-free in ImageMagick's PerlMagick Layer method allows an attacker supplying a crafted list of images to trigger memory access after deallocation, causing a crash. Affected versions include ImageMagick before 7.1.2-30 and the 6.9.x branch before 6.9.13-55. Impact is limited to denial of service (crash); no confidentiality or integrity compromise is possible from this flaw. No public exploit code or active exploitation has been identified at time of analysis.

Denial of service in GPAC 26.08-DEV can result from a use-after-free when a local user opens a crafted BIFS/MPEG-4 scene file containing malicious proto-library links. Exploitation requires local processing of an attacker-supplied file and the realistic outcome is an application crash with availability impact only; there is no demonstrated confidentiality or integrity impact and no demonstrated code execution. Publicly available exploit code exists, but the issue is low severity (CVSS 1.9 in the supplied 4.0 vector) and the independent assessment notes the PR:L requirement is questionable, viewing the attack as local file parsing with user interaction. The vulnerability is fixed in GPAC abi-16.24 via commit e34f4ba349d55cd1849f0bcf4cf46552732e2db7.
Local use-after-free in GPAC's scenegraph command handling (gf_sg_command_apply / gf_node_deactivate_ex) lets an attacker crash MP4Box and other GPAC-based tools when a victim opens or converts a crafted LASeR/SVG scene, or an MP4 that embeds one. The vector is local and requires the victim to process the malicious media, and the assessed impact is availability only (process crash; C:N/I:N/A:L) with no confidentiality or integrity loss and no demonstrated code execution. Publicly available exploit code exists (a PoC archive was published alongside the VulDB report), the issue is fixed by the GPAC abi-16.24 release, and it is explicitly distinct from CVE-2026-90827.
Heap use-after-free in the HDF5 library (The HDF Group, all versions before 2.3.0) is triggered when an application such as h5dump reads a dataset whose compound datatype contains floating-point members, allowing a crafted .h5 file to crash the parsing process and, depending on heap layout and allocator behaviour, potentially corrupt memory further. Exploitation requires the victim to open a malicious file locally (local vector, mandatory user interaction, no authentication needed), so it is not remotely reachable on its own. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV; the vendor's own CVSS 4.0 base of 4.6 aligns with the independent assessment that the reliably demonstrated impact is a crash rather than proven code execution.
Denial of service in ISC BIND 9 recursive resolvers: an attacker who controls (or compromises) an authoritative server for a DNSSEC-signed zone can cause `named` to abort after it encounters a use-after-free when processing a specific crafted sequence of answers. The attacker must first induce the victim resolver to issue multiple queries for that attacker-hosted zone, and the malicious responses must then arrive in a particular order and timing to trip the race, which is why this is rated high complexity (AC:H) despite being remote and unauthenticated (PR:N, no user interaction). Impact is availability-only (C:N/I:N/A:H), and exploitation is limited to `named` running as a recursive resolver on the listed versions; only 9.20.29 and later are fixed, and no public exploit code or confirmed active exploitation was identified at time of analysis.
Denial of service in NLnet Labs Unbound 1.12.0 through 1.26.0 arises from a use-after-free in the DNS-over-HTTPS (DoH) code path, reachable only in builds compiled with --with-libnghttp2 when failure conditions such as an RPZ drop action or heavy-traffic stream jostling occur. A remote, unauthenticated attacker can trigger the flaw with a single DoH connection and appropriate traffic, causing memory corruption that, under a hardened allocator, results in controlled termination of the Unbound process. No public exploit code has been identified at time of analysis; the impact is confined to availability (CVSS 5.9, C:N/I:N/A:H) with no confidentiality or integrity effect.
Unbound versions 1.22.0 through 1.26.1 built with DNS-over-QUIC support (--with-libngtcp2) can be driven to an abnormal exit by an unauthenticated remote attacker who manipulates QUIC stream state. The attacker sends a DoQ query, withholds ACKs, issues RESET_STREAM to free the per-stream output buffer, then waits for a PTO timeout so ngtcp2 re-encodes a STREAM frame from the freed memory; a spray of roughly 20 such queries forces the daemon down. Default builds compiled without QUIC support are not affected, and exploitation also requires precise timing against the QUIC state machine, making this a moderate, configuration-gated availability threat rather than a top-tier priority. No public exploit code and no confirmed active exploitation were identified at time of analysis, and the authoritative assessment rates it AV:N/AC:H/PR:N/UI:N/S:U with low confidentiality and high availability impact, so the practical outcome is denial of service against the resolver rather than broad data compromise.
Use-after-free in Chrome's Skia graphics library allows an attacker who has already compromised the renderer process to read cross-origin data after a victim opens a crafted HTML page in Chrome versions prior to 153.0.8010.47. Chromium rates the bug High severity because it can breach the same-origin boundary, even though the CVSS base score is only 3.1 (confidentiality-limited, no integrity or availability impact). No public exploit code or CISA KEV entry is associated with this CVE at time of analysis, and the attack is not automatable per CISA's SSVC assessment.
A use-after-free in the ARM SMMU v3 driver (arm-smmu-v3.c) of the Android kernel lets a local attacker who already holds System-level execution privileges corrupt kernel memory and escalate to full kernel/System privilege. The flaw is a logic error in one of several driver functions that leaves a freed object reachable, and no user interaction is needed once the attacker has code running at that privilege level. It is ranked CVSS 6.7 (AV:L/PR:H), there is no indication of active exploitation or public exploit code, and Google published a fix in the September 2026 Pixel security bulletin.
Use-after-free in FreeRDP's smartcard RDPDR device handler (before 3.31.0) allows a malicious or compromised RDP server to free a registered device pointer while the device manager still holds a reference, producing a dangling pointer that can crash the client or potentially be leveraged for code execution in the victim's session. The flaw is only reachable when a client with smartcard redirection enabled connects to an attacker-controlled RDP endpoint and the attacker can force a worker-thread creation failure during channel setup — a narrow, non-deterministic window reflected in the low CVSS 4.0 score of 2.3 (AV:N/AC:H/AT:P/PR:N/UI:P, availability-only impact). A vendor patch is available in FreeRDP 3.31.0; no public exploit code and no CISA KEV listing were identified at time of analysis.
Use-after-free in GPAC's scenegraph node handling allows a remote attacker to trigger memory corruption by delivering a crafted media file that is processed by the affected application. The vulnerability exists in `gf_node_get_name_and_id()` in `scenegraph/base_scenegraph.c`, where a node pointer could be dereferenced after being freed due to missing null/reference-count guards in the BIFS decoder's command assignment path. Exploitation requires user interaction (opening a malicious file), a publicly available proof-of-concept exists (poc_16_bt.zip), and no confirmed active exploitation is recorded in CISA KEV.
Use-after-free in GPAC's LASeR scene graph command processing subsystem allows remote attackers to corrupt heap memory by supplying a crafted media file, potentially leading to process crash or code execution. Affected are GPAC builds up to commit f1219cde; the flaw stems from direct node-pointer assignment without proper reference counting in the LASeR decoder and scene graph command application paths. A public proof-of-concept exploit is confirmed available; vendor-released patch exists at commit e34f4ba and release abi-16.24.
Use-after-free in zstd-jni's Dictionary Sharing component allows remote attackers to corrupt native heap memory through the ZstdCompressCtx.loadDict() and ZstdDecompressCtx.loadDict() APIs in versions up to 1.5.7-13. The defect is a logic inversion in shared-lock accounting: the code releases the reference count on the incoming dictionary parameter rather than on the previously held dictionary reference, causing the old native buffer to remain referenced after it can be freed by another thread. A public proof-of-concept exists via GitHub issue #404, and vendor released a confirmed fix in version 1.5.7-14.
A use-after-free memory-management flaw affects Apple's operating system family prior to the 26.6 releases — iOS and iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6 and watchOS 26.6 — and allows a locally installed app to trigger unexpected system termination (a denial-of-service condition). The vulnerability is rated CVSS 5.5 with a local attack vector, low complexity and low privileges required, but no confidentiality or integrity impact; EPSS is only 0.19 percent and there is no CISA KEV listing and no publicly available exploit code identified at time of analysis. Apple has shipped fixes in all four platform advisories, so the practical risk is concentrated on unpatched devices rather than on active exploitation.
A use-after-free (CWE-416) in Apple's memory management code allows a locally running application on iOS, iPadOS, macOS, tvOS, visionOS and watchOS to crash the affected system, producing an unexpected termination or reboot. The flaw affects all platforms before the fixed releases (iOS/iPadOS 26.7 and 27, macOS Sequoia 15.8, macOS Tahoe 26.7, macOS Golden Gate 27, tvOS 27, visionOS 27, watchOS 27) and rates CVSS 5.5 (AV:L/PR:L/UI:N, availability-only impact). No public exploit code or active exploitation has been identified, and EPSS is low at 0.21% (11th percentile), so this is a patched, availability-only issue rather than an urgent remote-code-execution threat.
A use-after-free in macOS memory management allows a locally running application to crash the operating system, resulting in unexpected termination and loss of unsaved work. The flaw affects macOS Tahoe before 26.6, macOS Sequoia before 15.7.8, and macOS Sonoma before 14.8.8, with exploitation requiring only low privileges (CVSS PR:L) and no additional user interaction. Apple has released fixes (patch available per vendor advisories), and although EPSS is very low at 0.19% (9th percentile) with no CISA KEV listing, no public exploit code identified at time of analysis, the flaw is a memory-safety bug that carries inherent risk of escalation beyond a simple denial of service.
A use-after-free memory management flaw in Apple iOS and iPadOS allows a locally installed application to crash the system, causing unexpected device termination (denial of service). All versions prior to iOS 27 / iPadOS 27 are affected per the vendor CPE wildcard and ENISA EUVD version range (0 < 27). Apple addressed the issue with improved memory management in iOS 27 and iPadOS 27; no public exploit code has been identified and the EPSS probability is very low (0.17%, 7th percentile), so this is primarily a stability/patch-hygiene issue rather than an active exploitation threat.
Unexpected system termination can be triggered on Apple devices by a locally executed app that exploits a use-after-free memory corruption in shared system code, which Apple addressed through improved memory management. The flaw affects essentially every current Apple OS branch below the fixed releases — iOS/iPadOS 26.6+, macOS 15.8/26.6+/27, tvOS 26.6+/27, visionOS 26.6+/27 and watchOS 26.6+/27 — with CVSS 5.5 reflecting an availability-only impact and a local attack vector. EPSS is low (0.24%, 16th percentile), no public exploit code has been identified, and there is no CISA KEV entry, so this is a routine patch-cycle item rather than an urgent threat.
A use-after-free (CWE-416) in the Apple macOS SMB client allows a maliciously crafted SMB network share to crash the operating system, causing system termination. Exploitation requires the user to mount the attacker-controlled share (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, base 6.5), so impact is limited to denial of service with no confidentiality or integrity loss. Apple has released fixes in macOS Golden Gate 27, macOS Sequoia 15.8, and macOS Tahoe 26.7; there is no CISA KEV listing and no public exploit code identified, and EPSS is low at 0.17% (6th percentile).
A use-after-free memory-management flaw in Apple's operating systems allows a locally installed application to crash the system, causing unexpected termination (denial of service) on affected iPhone, iPad, Mac, and Apple Vision Pro devices. Apple addressed the issue across iOS 26.7/iPadOS 26.7, iOS 27/iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, and visionOS 27. There is no evidence of active exploitation: CISA KEV does not list the CVE, SSVC records exploitation as 'none' and automatable as 'no', EPSS is a low 0.18% (7th percentile), and no public exploit code has been identified at the time of analysis.
A use-after-free write in the Zephyr RTOS ITE IT82xx2 USB device-controller driver (drivers/usb/udc/udc_it82xx2.c) affects Zephyr 4.0.0 through 4.4.1 and allows a malicious USB host to create a kernel heap-corruption primitive on the device side. When a multi-packet OUT transfer is received on a non-control endpoint, the driver re-arms the endpoint to keep filling the same net_buf while simultaneously handing that buffer to the upper USB device stack, which may free and recycle it while DMA continues; the completing packet is also submitted a second time, corrupting the event slist and causing a double net_buf_unref(). Exploitation is physical (USB attach) with no authentication or user interaction required, giving a reliable denial of service and plausible adjacent-pool memory corruption; no public exploit code or CISA KEV listing was identified for this CVE at time of analysis.
A use-after-free and double-free race in Zephyr's TLS socket session cache lets a malicious or compromised TLS peer corrupt the mbedTLS heap and crash an affected device. The flaw is reachable only by applications that explicitly enable the TLS_SESSION_CACHE socket option (off by default) and run concurrent TLS client connections from multiple threads, since the process-global client_cache defaults to a single shared slot. A vendor fix exists in commit 7f9d8ee (shipping in Zephyr 4.4.2 per the EUVD version range), and no public exploit code or active exploitation has been identified.
A use-after-free in GPAC's scene-graph handling (gf_sg_script_load path) lets a crafted MP4/VRML scene file corrupt memory when processed by MP4Box or any application embedding libgpac. Publicly available exploit code exists and the flaw is remotely deliverable, though exploitation requires the victim or an ingestion pipeline to actually open the malicious media file (UI:P). A vendor fix is available in release abi-16.23 / commit 9eb40df4448b88d6a6ce3454657c06f47eff0b24, and the CVSS 4.0 base score is only 2.1 because confidentiality, integrity and availability impacts are all rated Low.
Use-after-free
Use-after-free in GPAC's `gf_node_unregister` function (scenegraph/base_scenegraph.c) allows an attacker to cause a crash or limited memory corruption by supplying a crafted MP4, BT, or XMT scene file. The vulnerability arises from improper cleanup ordering of proto field default node values during scene graph teardown, with additional related issues in the BT and XMT scene loaders. A public proof-of-concept exploit exists (GitHub issue #3801 and dedicated write-up), though the CVSS 4.0 score of 2.1 and all-Low impact metrics indicate reliable code execution is unlikely - DoS via crash is the primary realistic outcome. No CISA KEV listing exists.
Use-after-free in Open5GS AMF component versions 2.0.x through 2.7.x allows network-reachable attackers to corrupt memory in the Access and Mobility Management Function process by triggering the old AMF discovery fallback handler with a crafted interaction. The root cause is premature deallocation of the SBI transaction structure (`ogs_sbi_xact_remove`) before the `discovery_option` argument derived from that structure is fully consumed; the fix relocates the free call past all dependent uses. No public exploit code has been identified; an upstream patch commit is available.
Use-after-free in GPAC's scene graph management allows remote attackers to cause memory corruption via a crafted multimedia scene file. The flaw exists in `gf_node_changed_internal` within `base_scenegraph.c` and is triggered when GPAC's BT/XMT scene loaders fail to properly track node lifecycle, leaving dangling references to freed nodes in `def_nodes` lists and proto field structures. A public proof-of-concept exploit has been disclosed and the vendor has released a fix in tag abi-16.23. No confirmed active exploitation (KEV) is recorded at time of analysis.
Use-After-Free in the Samsung Exynos DRM HDR kernel driver causes a kernel crash on devices running Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600 SoCs. The defect lies in the error-handling path of the HDR driver: when a vmap() call fails, cleanup does not properly invalidate the freed mapping, leaving a dangling reference that is subsequently dereferenced, crashing the kernel. The CVSS vector (AV:L/AC:H/PR:L) indicates a local low-privileged attacker can trigger this under specific error conditions, crossing into kernel scope (S:C). No public exploit code or active exploitation has been identified at time of analysis.
Use-after-free in GPAC's MP4Box multimedia tool (all versions through commit f1219cde) allows a local low-privileged attacker to corrupt heap memory via the gf_list_count function in utils/list.c, resulting in application crashes and potentially limited code execution within the process. The fix released in abi-16.23 (commit 49dee5cad329) addresses multiple interrelated UAF and null-dereference conditions across the scenegraph manager, BIFS memory decoder, and AV1 reframer subsystems. A public proof-of-concept exploit exists; no active exploitation has been confirmed via CISA KEV.
Use-after-free in Suricata 8.0.0-8.0.4 causes an engine crash when a malicious detection rule chains decompress transforms (gunzip or zlib_deflate with max-size exceeding 4096) after another transform, allowing the pipeline to read from a freed inspection buffer during subsequent network traffic processing. The net effect is a reliable denial-of-service: once the offending rule is loaded, any matching network traffic will crash the Suricata process regardless of traffic content. No public exploit or active KEV listing exists at time of analysis. Vendor-released patch is available in version 8.0.5.
Use-after-free in Suricata's inspection-buffer helper crashes the IDS/IPS engine, yielding a network-exploitable denial-of-service against any deployment running rules that chain the `dotprefix` transform after another transform. Affected versions prior to 7.0.16 (stable) and 8.0.5 include all prior 7.x and 8.x releases. No public exploit code and no CISA KEV listing have been identified; exploitation requires an attacker to know or guess that the target's ruleset matches the vulnerable pattern, and then craft traffic to trigger the reallocation path.
Heap use-after-free in DaveGamble cJSON's cJSONUtils_MergePatch function (cJSON_Utils.c) affects all versions through 1.7.19 when the patch argument is a subtree of the target object. The function deletes the target before duplicating the patch, freeing the patch memory and causing a subsequent read of freed heap - confirmed by an AddressSanitizer-triggering test case in upstream fix PR #1065. A public exploit exists (GitHub issue #1060) and can lead to crash, potential memory disclosure, or memory corruption in any application that passes attacker-influenced JSON through this specific merge-patch call pattern.
A crafted series of RTSP and HTTP requests sent to LIVE555 Streaming Media 2026.02.26 triggers a use-after-free in SocketDescriptor::tcpReadHandler1 (liveMedia/RTPInterface.cpp), crashing the media server and terminating all active streams. The flaw is reachable over the network without credentials, and because LIVE555 is embedded in IP cameras, streaming appliances and media servers, one crash can disrupt many downstream viewers at once. No public exploit code and no CISA KEV entry were identified at time of analysis, EPSS places exploitation probability at roughly 0.15% (5th percentile), and the supplied references do not state an exact fixed build number.
Use-after-free in Chrome's V8 JavaScript engine enables an attacker with a pre-compromised renderer process to read arbitrary memory within the sandbox boundaries via a crafted HTML page. Affected versions are Chrome prior to 153.0.8010.36 on all desktop platforms. Unlike most Chrome UAF findings that achieve sandbox escape, this vulnerability is constrained to intra-sandbox memory disclosure (C:L, S:U), making it a stepping-stone primitive rather than a standalone critical exploit. No public exploit code or CISA KEV listing exists at time of analysis.
Use-after-free in Adobe Acrobat Reader and Acrobat exposes sensitive heap memory contents when a victim opens a specially crafted PDF file. The vulnerability affects Acrobat and Acrobat Reader up to version 26.002.21900 and Acrobat 2024 up to 24.001.30383, with confidentiality impact rated High by Adobe PSIRT. No public exploit code has been identified at time of analysis, and exploitation requires the victim to open a malicious file.
Use After Free (CWE-416) in Adobe Acrobat and Acrobat Reader permits sensitive memory disclosure when a victim opens a maliciously crafted document. Affected versions span Acrobat and Acrobat Reader ≤26.002.21900 and Acrobat 2024 ≤24.001.30383. The memory-corruption primitive exposes heap contents - potentially including credentials, key material, or in-process data - but the CVSS vector confirms no integrity or availability impact, making this a pure information-disclosure issue. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Use-after-free in Windows Distributed File System (DFS) enables an authenticated network attacker to crash the DFS service, resulting in denial of file-sharing access across affected Windows client and server versions. The CVSS vector (AV:N/AC:H/PR:L) confirms network reachability but constrains exploitation to low-privilege authenticated accounts under high-complexity conditions. Microsoft has released patches covering the full affected range from Windows 10 1607 through Windows Server 2025; no public exploit code or active exploitation has been identified at time of analysis.
Use-after-free (CWE-416) in Microsoft Office Word enables a locally authenticated attacker to disclose sensitive memory contents. Exploitation requires only low-privileged local access with no user interaction, yielding high confidentiality impact per the CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N vector. No public exploit or active exploitation has been identified at time of analysis, and a vendor-released patch is available through Microsoft's update mechanism.
Use-after-free in MongoDB Server's cursor management component allows an authenticated remote attacker to crash the mongod server process, causing a denial of service. Under specific timing conditions during cursor lifecycle events, a stale pointer to a freed resource is retained and later dereferenced during cursor cleanup, producing undefined behavior and a process crash. Affected branches are MongoDB 7.0.x before 7.0.41, 8.0.x before 8.0.30, and 8.3.x before 8.3.9; vendor-patched releases are available, and no public exploit code is identified at time of analysis.
Heap use-after-free in MongoDB Server's text index query parser allows authenticated users with readWrite privileges to crash the server process through deliberate concurrent operations. By combining upsert retry text-search queries with concurrent index lifecycle operations (create/drop) on the same collection, an attacker can trigger a race window where a raw pointer to freed text index metadata structures is dereferenced, aborting the mongod process and causing denial of service for all connected clients. No public exploit has been identified; vendor patches are available for all three affected release lines (7.0.x, 8.0.x, 8.3.x).
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture Kernel Drivers allows a local non-privileged process to access already-freed GPU memory through otherwise-valid GPU memory processing operations. The flaw spans a wide range of driver releases across all three GPU families - covering most modern Arm Mali GPU generations deployed in Android SoCs from r41p0 onward. No public exploit code or active exploitation has been identified; EPSS sits at 0.14% (4th percentile), and the vulnerability is not listed in the CISA KEV catalog.
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture kernel drivers allows an unprivileged local process to access already freed kernel memory, leaking limited sensitive data. The flaw is triggered through valid GPU memory processing operations, requiring no special privileges beyond local code execution - a realistic threat on mobile devices running affected Mali GPU firmware. With EPSS at 0.14% and no public exploit or KEV listing, active exploitation is not currently observed, but the breadth of affected versions across three GPU families and many Android SoC generations elevates overall exposure.
Use-after-free memory access in Arm's Valhall and 5th Gen GPU Architecture userspace drivers allows a non-privileged local process - including browser-hosted WebGL or WebGPU workloads - to read and write already-freed GPU memory regions, yielding limited confidentiality and integrity compromise. Arm reported this issue internally; no active exploitation has been identified. The wide deployment of Arm Mali GPU hardware in mobile and embedded SoCs makes the affected driver versions relevant across a large device population, though the limited CVSS impact scores constrain severity.
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU kernel drivers allows a local unprivileged process to access already-freed GPU memory through valid GPU memory processing operations, resulting in limited confidentiality and integrity impact against the kernel driver. The flaw spans a wide range of driver versions across all three GPU architectures, affecting the enormous ecosystem of Android and embedded devices powered by Arm Mali GPUs. No public exploit or active exploitation has been identified; SSVC rates technical impact as partial and exploitation as none at time of analysis.
Heap-use-after-free in ImageMagick's PerlMagick Layer method allows an attacker supplying a crafted list of images to trigger memory access after deallocation, causing a crash. Affected versions include ImageMagick before 7.1.2-30 and the 6.9.x branch before 6.9.13-55. Impact is limited to denial of service (crash); no confidentiality or integrity compromise is possible from this flaw. No public exploit code or active exploitation has been identified at time of analysis.
