Heap Overflow
Monthly
Remote code execution in Google Chrome desktop before 152.0.7977.65 stems from a heap buffer overflow in the WebGL component, and critically allows an attacker to execute code OUTSIDE the renderer sandbox (scope change) via a single crafted HTML page. Any user who browses to a malicious or compromised site is at risk, requiring only that the page load and render WebGL content. No public exploit has been identified at time of analysis, and EPSS exploitation probability is low (0.39%), but the sandbox-escape impact and network reachability make this a high-priority patch.
Heap-based buffer overflow in ANGLE (Almost Native Graphics Layer Engine) within Google Chrome for Android prior to 152.0.7977.65 enables remote code execution outside the renderer sandbox via a crafted HTML page, meaning a successful attacker escapes Chrome's process isolation boundary with full C/I/A impact. Exploitation requires no authentication and only that a victim navigate to an attacker-controlled page, making drive-by compromise via phishing or malvertising a realistic delivery path. No public exploit has been identified at time of analysis and no CISA KEV listing exists, though the sandbox-escape capability significantly elevates real-world priority beyond what the raw CVSS score alone conveys.
Remote code execution outside the browser sandbox affects Google Chrome desktop builds prior to 152.0.7977.65, stemming from a heap buffer overflow in the ANGLE graphics translation layer. A remote attacker who lures a victim into loading a crafted HTML page can execute arbitrary code that escapes the renderer sandbox (CVSS 9.6, scope-changed). No public exploit identified at time of analysis, and EPSS is low (0.28%, 20th percentile), but the sandbox-escape impact and universal Chrome deployment make patching urgent.
Heap out-of-bounds write in OpenEXR's exrmultiview utility allows an attacker who can supply crafted EXR files to corrupt heap memory when the tool combines two individually valid scanline EXR files whose union dataWindow is misaligned to one view's channel subsampling. Affected are OpenEXR versions across three maintained branches (pre-3.2.11, 3.3.0-3.3.12, and 3.4.0-3.4.13), all fixed in their respective patch releases. No public exploit or CISA KEV listing has been identified at time of analysis, though the attack is achievable via normal command-line invocation with attacker-supplied files in VFX pipeline contexts.
Heap buffer overflow in PyOpenEXR versions 3.3.0-3.3.12 and 3.4.0-3.4.13 allows an attacker to corrupt process memory by supplying a crafted EXR image file containing conflicting literal and prefixed RGB channel names. When the Python wrapper decodes such a file under the default separate_channels=False mode, a channel-name key collision causes the coalescing logic to reuse an undersized NumPy array and write pixel data out of bounds on the heap, producing high integrity and availability impact with no confidentiality exposure. No public exploit code has been identified and no active exploitation is confirmed; patched releases 3.3.13 and 3.4.14 are available from the Academy Software Foundation.

Heap-based buffer overflow in Adobe Substance 3D Designer enables arbitrary code execution in the context of the victim user when a malicious project or asset file is opened. The CVSS vector (AV:L/AC:L/PR:N/UI:R) confirms local file-based exploitation with no privileges required on the attacker side, but requiring the victim to actively open a crafted file. No public exploit code or CISA KEV listing has been identified at time of analysis; the vendor has issued advisory APSB26-115 addressing this issue.
Heap-based buffer overflow in Adobe Substance 3D Designer enables arbitrary code execution scoped to the victim's user account when a crafted file is opened. The CWE-122 flaw carries a CVSS 7.8 (High) rating with full confidentiality, integrity, and availability impact, making successful exploitation highly damaging despite the required file-open interaction. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity once file delivery is achieved keeps this a credible threat to creative professionals.
Heap out-of-bounds write in OpenEXR 3.3.0-3.3.12 and 3.4.0-3.4.13 allows an attacker who can supply a crafted deep scanline EXR file to crash the exrmetrics utility or potentially execute arbitrary code when pixel conversion options are active. The flaw arises from a HALF/FLOAT element-size mismatch: sample buffers are allocated for 2-byte HALF input while DeepSlice writes 4-byte FLOAT output, overrunning the heap. No public exploit or active exploitation has been identified at time of analysis; fixed releases 3.3.13 and 3.4.14 are available.
Heap out-of-bounds write in OpenEXR's TiledRgbaInputFile RGBA API affects all three active release lines on 32-bit/ILP32 builds, allowing a remote attacker to deliver a crafted EXR file that crashes or corrupts the heap of any application that opens it. The root cause is a 32-bit integer overflow in the Array2D<Rgba> buffer size calculation when tile dimensions (65537×65537) are encoded in the file header but the actual dataWindow is tiny (40×40), causing the allocator to produce an undersized buffer that tile decode then overflows. No public exploit code has been identified and the vulnerability is not listed in CISA KEV; vendor-released patches are available across all three affected release branches.
Remote code execution in Konami's Metal Gear Online 3 (build 1.1.2.8) arises from an unbounded heap write when parsing the lobby's kicked-player list: the game trusts the attacker-supplied "kick_num" count without checking it against the 16-player buffer limit. A malicious lobby participant can overflow the kicked-ID buffer into adjacent Steam callback handler structures, corrupting function pointers to hijack control flow and potentially execute arbitrary code inside the game process. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the network-reachable, unauthenticated nature and RCE potential make it high-severity.
Heap out-of-bounds write in LibVNCClient 0.9.12-0.9.15 allows a malicious or man-in-the-middle VNC server to corrupt client heap memory with attacker-controlled data, leading to unconditional denial of service or demonstrated remote code execution via callback pointer overwrite. The flaw fires from a single FramebufferUpdate message the moment a victim connects, requires no authentication, and works against default builds with default settings. No public exploit has been identified at time of analysis, though the GitHub Security Advisory explicitly demonstrates code execution under default configuration.
Heap buffer overflow in Capstone's SuperH (SH) architecture floating-point disassembler affects all releases through 6.0.0-Alpha9, allowing a four-byte out-of-bounds write into heap memory when processing crafted SH instructions. The root cause is that opFADD, opFMUL, opFSUB, and related SH FPU decoders in arch/SH/SHDisassembler.c increment op_count as an array index into the fixed-size operands[] array without bounds checking, overflowing the 176-byte sh_info heap allocation. A process that disassembles attacker-controlled SH binary data with the affected mode flags can be crashed; code execution is possible but depends on heap layout. No public exploit has been identified at time of analysis, though a proof-of-concept test case is included in the upstream fix PR. The vendor-released patch is version 6.0.0-Alpha10.
Integer overflow in libvips prior to 8.18.3 allows an attacker who can supply a crafted many-band TIFF image to evade scanline validation in VipsForeignLoadTiff, producing heap-region miscalculations that enable reads or writes at attacker-controlled negative offsets within mmap-resident allocations. Affected deployments include any pipeline - web applications, batch processors, or CLI tools - that pass untrusted TIFF input through libvips, with confirmed impacts of data disclosure via uncompressed .v output and near-certain process crashes; remote code execution has not been demonstrated but is explicitly not ruled out by the vendor. No public exploit or CISA KEV listing exists at time of analysis; the upstream fix is confirmed in v8.18.3.
Remote code execution outside Chrome's sandbox via a heap-based buffer overflow in the Network component affects Google Chrome prior to 151.0.7922.173. An unauthenticated remote attacker can trigger the flaw by directing a target user to a crafted HTML page, achieving arbitrary code execution that escapes Chrome's sandbox boundary with full confidentiality, integrity, and availability impact (CVSS 8.8). No public exploit has been identified at time of analysis, and EPSS signals low current exploitation probability (0.39%, 32nd percentile); however, the sandbox-escape characteristic elevates the strategic patching priority beyond what the EPSS alone would suggest.
Heap-based buffer overflow in GIMP's TIF file parser enables remote code execution when a user opens a crafted TIFF image, affecting GIMP 3.2.2. The flaw stems from missing length validation before copying attacker-controlled data into a heap buffer (CWE-122), granting full code execution in the context of the GIMP process. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but a fix commit is available on the GNOME GitLab repository.
Heap-based buffer overflow in GIMP's TIF file parser (CWE-122) enables remote code execution on affected installations when a user opens a crafted TIFF image. Confirmed affected version is GIMP 3.2.2 per EUVD-2026-63451, with the flaw originating from missing length validation before copying attacker-controlled data to a heap buffer. Discovered and reported by Zero Day Initiative (ZDI-26-455 / ZDI-CAN-29398); no public exploit or CISA KEV listing has been identified at time of analysis, though an upstream patch commit exists on GNOME GitLab.
Heap-based buffer overflow in GStreamer's PNG file parsing allows remote code execution in the context of the affected process. Affects GStreamer installations where a user can be induced to open or process a maliciously crafted PNG file - via a web page or file download. The flaw stems from missing length validation before copying attacker-controlled data into a heap buffer (CWE-122). No public exploit or CISA KEV listing is identified at time of analysis; however, ZDI disclosed the issue under ZDI-26-466 following coordinated disclosure, and GStreamer has issued security advisory sa-2026-0052.
Heap-based buffer overflow in GStreamer's MRF file parser enables remote code execution when a user opens a crafted media file or visits a page that triggers parsing. The root cause is absent length validation before copying attacker-supplied data into a heap buffer (CWE-122), granting full confidentiality, integrity, and availability impact within the target process. Reported by ZDI as ZDI-CAN-29608 and addressed in GStreamer security advisory SA-2026-0050; no public exploit code or CISA KEV listing is confirmed at time of analysis.
Remote code execution in the Sony XAV-9500ES automotive multimedia head unit is achievable by a network-adjacent attacker who can induce a victim to pair a malicious Bluetooth device. The root cause is a heap-based buffer overflow (CWE-122) in the AVRCP_Br_Response_Parser function, which fails to validate the length of attacker-controlled data before copying it into a heap allocation. Successful exploitation yields arbitrary code execution at the device level; no public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV.
Heap-based buffer overflow in the Sony XAV-9500ES car multimedia receiver's Bluetooth L2CAP SDU reassembly function enables network-adjacent attackers to execute arbitrary code on the device. The flaw in `l2_reassemble_sdu` stems from missing length validation before copying attacker-controlled data to a heap buffer, granting full code execution in the device context once a malicious Bluetooth device has been paired by the victim. No public exploit or CISA KEV listing has been identified at time of analysis, but the ZDI advisory (ZDI-26-474) and a Sony firmware update advisory are both publicly available.
Denial of service via heap-based buffer overflow affects IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1, exploitable by remote unauthenticated attackers. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms no authentication or user interaction is required, making this a low-friction remote availability attack against IBM Power Systems infrastructure. No active exploitation or public exploit code has been identified at time of analysis; a vendor patch is available via IBM's support portal.
Heap-based buffer overflow in Wireshark's RDP protocol dissector (CWE-122) crashes the application when processing malformed RDP traffic, causing denial of service across two active release branches. Affected versions span 4.4.0-4.4.17 and 4.6.0-4.6.7 of the Wireshark Foundation's Wireshark (CPE: cpe:2.3:a:wireshark_foundation:wireshark). A proof-of-concept exists per SSVC data, though EPSS (0.17%, 7th percentile) and SSVC's 'Automatable: no' assessment indicate real-world mass exploitation is not occurring; no public exploit identified at time of analysis beyond the poc designation, and the flaw is absent from CISA KEV.
Denial of service in Wireshark's C12.22 protocol dissector affects versions 4.6.0-4.6.7 and 4.4.0-4.4.17, where a malformed C12.22 packet triggers a heap buffer overflow (CWE-122) that crashes the application. An attacker who can get crafted traffic in front of a capturing or file-loading analyst can reliably terminate the dissection session. A proof-of-concept is reported via SSVC, but there is no evidence of active exploitation, and the EPSS probability is low (0.27%).
Heap buffer overflow in FreeRDP's Opus audio codec path allows a malicious RDP server to corrupt client heap memory and potentially execute arbitrary code on any connecting client built with WITH_OPUS enabled and WITH_DSP_FFMPEG disabled. The flaw in freerdp_dsp_decode_opus (versions prior to 3.28.0) stems from a capacity check applied to the wrong buffer, leaving the actual PCM output buffer unguarded against oversized libopus decoded frames that can overrun the fixed 4096-byte StreamPool_Take destination in the rdpsnd channel. No public exploit has been identified at time of analysis, but the confirmed heap write primitive and RCE classification make this a credible code execution risk for susceptible client builds connecting to untrusted servers.
Heap buffer overflow in FFmpeg's VC-2/Dirac RTP packetizer (libavformat/rtpenc_vc2hq.c) enables memory corruption via crafted Dirac data units across all versions prior to fix commit 1cdeb3c. The packetizer accepts an attacker-controlled data unit or fragment size and copies it into a fixed-size heap buffer without an upper-bound check, a classic CWE-122 condition with High confidentiality, integrity, and availability impact. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; an upstream fix commit is available from the FFmpeg repository.
Heap buffer overflow in FFmpeg's RIST protocol reader (libavformat/librist.c) lets a remote RIST sender corrupt heap memory in any FFmpeg instance ingesting an async:rist:// stream, enabling potential remote code execution or crash. The librist_read() function ignores the caller's buffer size and copies the entire received RIST payload into a destination buffer that the async wrapper sizes smaller than the packet, so an oversized payload writes past the buffer end. Reported by VulnCheck and fixed upstream in commit 1c10bcc; no public exploit is identified at time of analysis and it is not listed in CISA KEV.
Heap buffer overflow in FFmpeg's hvcC box writer exposes any version prior to commit acf5d7c to memory corruption during HEVC muxing. When a crafted HEVC file presents more NAL units of a single type than the count field can encode, integer overflow corrupts heap memory, potentially enabling arbitrary code execution in the FFmpeg process context. No public exploit has been identified at time of analysis and no CISA KEV listing exists, but server-side transcoding pipelines ingesting untrusted HEVC content effectively elevate the local-vector risk to a network-reachable attack surface.
Heap buffer overflows in FreeBSD's iconv(3) character-conversion library allow attackers who control input processed through the HZ, UTF-7, VIQR, or ZW encoding modules to corrupt heap memory, potentially leading to remote code execution. Applications on FreeBSD 14.3/14.4/15.0/15.1 that pass untrusted data through iconv using any of these encodings are exposed. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.21%, 12th percentile) despite the 9.8 CVSS.
Kernel memory corruption in FreeBSD's ZFS subsystem allows a local user with the delegated 'receive' ZFS permission to trigger a heap-based buffer overflow via the ZFS_IOC_RECV_NEW ioctl. The flaw stems from an integer truncation: a 64-bit payload size is silently narrowed to 32 bits for heap allocation, but the original 64-bit value is then used as the length for a subsequent byteswap operation - writing beyond the allocated buffer into kernel memory. Exploitation is limited to the heal receive path and requires the ZFS 'receive' delegation, but no patch has been publicly released yet for all affected branches. No public exploit code or CISA KEV listing has been identified at time of analysis.
Kernel heap overflow in FreeBSD's ZFS subsystem via the ZFS_IOC_USERSPACE_MANY ioctl enables local privilege escalation across multiple supported FreeBSD release branches. The flaw stems from an integer width mismatch: the kernel allocates a heap buffer sized by a 32-bit truncation of the caller-supplied 64-bit length, then copies records up to the original 64-bit limit - writing past the end of the allocation. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the low attack complexity and high impact across confidentiality, integrity, and availability make patching a priority for any FreeBSD deployment that uses ZFS delegated permissions.
Sandbox escape via heap-based buffer overflow in ANGLE's graphics engine on Chrome for Android allows a threat actor who has already achieved renderer process compromise to execute arbitrary code entirely outside the Chrome sandbox. All Chrome for Android versions prior to 151.0.7922.169 are affected; the vulnerability requires a two-stage exploit chain combining a separate renderer compromise with this ANGLE flaw. Google has released a patched build (151.0.7922.169); no public exploit code or CISA KEV listing has been identified at time of analysis, though the two-stage nature indicates likely use in sophisticated targeted attack chains.
Remote code execution in Google Chrome for Android before 151.0.7922.169 stems from a heap buffer overflow in Dawn, Chromium's WebGPU implementation, and is notable because Google explicitly states it allows code execution OUTSIDE the renderer sandbox. A remote attacker who lures a victim to a crafted HTML page can achieve full compromise of the browser process context on the device. Rated Critical by Chromium with CVSS 9.6; a vendor patch is available, and no public exploit has been identified at time of analysis.
Heap-based buffer overflow in Google Chrome's WebGL implementation (all versions prior to 151.0.7922.169) enables a remote attacker to execute arbitrary code outside the browser sandbox by luring a user to a crafted HTML page. The sandbox escape elevates the impact from renderer-level code execution to potential full OS-level compromise. No public exploit code or active exploitation has been identified at the time of analysis, but the SSVC technical impact rating is 'total,' reflecting the severity of successful exploitation.
Heap-based buffer overflow in Open5GS v.2.7.0 allows remote unauthenticated attackers to crash the NAS 5GS decoder chain by sending a NAS PDU with a mutated message type byte, resulting in denial of service to the AMF component and all connected UEs. The vulnerability is network-accessible with no authentication or user interaction required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N), making it trivially reachable from any host with access to the AMF N1 interface. A public proof-of-concept exploit exists, no public exploit identified as confirmed active exploitation (no CISA KEV listing), and no vendor patch has been confirmed at time of analysis.
Remote code execution in Systerel S2OPC 1.7.3 arises from a heap out-of-bounds write in the server-side EventFilter handling path exercised during CreateMonitoredItems processing. A remote attacker who can reach the OPC UA server endpoint and open a session on an events-enabled server can corrupt heap memory to achieve arbitrary code execution with the privileges of the server process. No public exploit identified at time of analysis, and EPSS is low (0.27%, 20th percentile), indicating the CVSS 9.8 rating reflects potential impact rather than observed mass exploitation.
Remote code execution in Microsoft Edge (Chromium-based) is enabled by a heap-based buffer overflow (CWE-122) that network-accessible, unauthenticated attackers can trigger when a victim interacts with attacker-controlled content. The CVSS 3.1 score of 8.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L) reflects high confidentiality and integrity impact with low attack complexity, requiring only that the user visit or open a crafted resource. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Heap buffer overflow in PostgreSQL's pg_dump backup utility across all active major versions enables an authenticated database user with object creation privileges to execute arbitrary code as the operating system account running pg_dump. The attacker plants a crafted database object containing an excessively long function transform list, then waits for pg_dump to process that object during a backup operation, triggering CWE-122 heap corruption. No public exploit has been identified at time of analysis, but the clear trigger path and widely deployed target surface make this a meaningful operational risk for organizations relying on pg_dump for backup automation.
Heap buffer overflow in PostgreSQL's pg_stat_statements extension (major version 18, minor versions 18.0 through 18.4) allows any authenticated database user to execute arbitrary code as the operating system account running the PostgreSQL service by submitting crafted SQL queries containing array constants. The CVSS vector (AV:N/AC:L/PR:L/UI:N) indicates low-complexity network exploitation requiring only a valid database credential, with full confidentiality, integrity, and availability impact on the database host. No public exploit code has been identified at time of analysis, and this CVE is not currently listed in the CISA KEV catalog.
Heap buffer overflow in PostgreSQL's plperl extension allows a database function owner to execute arbitrary code as the OS-level user running the database server by crafting a function body that returns a tied hash. Affected versions span the four active PostgreSQL major release lines prior to 18.5, 17.11, 16.15, 15.19, and 14.24. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Heap buffer overflow in PostgreSQL's to_char(timestamptz) function allows any authenticated database user to execute arbitrary code as the operating system account running the database process by supplying an excessively long POSIX timezone abbreviation. Affected versions span the actively maintained major release lines: PostgreSQL 14 through 18, with fixes available in 14.24, 15.19, 16.15, 17.11, and 18.5. No public exploit code has been identified at time of analysis, but the low attack complexity and broad deployment surface of PostgreSQL make this a high-priority patching target for any environment where untrusted or semi-trusted database users exist.
Heap buffer overflow in PostgreSQL's regexp engine allows any authenticated database user to execute arbitrary code as the operating system user running the database process. The flaw is triggered by specially crafted text that survives input validation but undergoes unanticipated data growth during internal round-trip conversion through the pg_wchar encoding layer, overflowing a heap-allocated buffer during regular expression evaluation. All active PostgreSQL branches are affected - versions prior to 18.5, 17.11, 16.15, 15.19, and 14.24 - with no public exploit or CISA KEV listing confirmed at time of analysis.
Heap-based buffer overflow in the MongoDB BI Connector ODBC Driver enables process memory disclosure, process termination, or arbitrary code execution when an application processes crafted stored procedure output parameter metadata returned by a malicious or impersonated database server. All versions prior to v1.4.9 are affected (CPE: cpe:2.3:a:mongodb:bi_connector_odbc_driver:*:*:*:*:*:*:*:*), and the attack does not require privileges against the driver itself, though the attacker must control or impersonate the upstream database server. MongoDB has released a patched version (v1.4.9) that adds buffer-clamping logic to prevent the overflow; no public exploit has been identified at time of analysis.
Heap out-of-bounds read and write in FreeRDP's Kerberos SSPI layer (all versions prior to 3.30.0) allows a malicious RDP peer to corrupt memory during CredSSP/NLA Kerberos decryption by supplying a crafted GSS Wrap-token with an unbounded EC or EC+RRC field value. The flaw sits in the pre-session authentication path, meaning exploitation does not require an established authenticated session from the attacker's side. No public exploit has been identified at time of analysis and CISA KEV listing is absent, but the network-reachable attack surface during a common enterprise authentication flow warrants prompt patching.
Remote code execution affects Microsoft Azure Attestation service and Device Health Attestation Service via an integer overflow condition that leads to a heap-based buffer overflow (CWE-122). Unauthenticated network attackers can exploit this flaw - confirmed by PR:N in the CVSS vector - though the high attack complexity (AC:H) indicates precise exploitation conditions must be met. No public exploit code or CISA KEV listing has been identified at time of analysis, but the potential impact is critical: full compromise of confidentiality, integrity, and availability on the affected service.
Privilege escalation via heap-based buffer overflow in Windows Installer (msiexec) allows a low-privileged local user to gain full system control. Affected product is Microsoft Windows across versions that ship with the vulnerable Windows Installer component; exact version scope is defined by the MSRC advisory. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA's KEV catalog, though its low-complexity, no-user-interaction profile makes it a realistic post-foothold escalation tool.
Privilege escalation in Windows Installer exposes all supported Windows systems to SYSTEM-level compromise by any low-privileged local user. The heap-based buffer overflow (CWE-122) in the Installer service requires only an authenticated local session - no user interaction, no elevated credentials, and low attack complexity per CVSS:3.1/AV:L/AC:L/PR:L/UI:N. No public exploit code or active exploitation via CISA KEV has been identified at time of analysis, but the ubiquity of Windows Installer and the straightforward exploitation conditions make this a meaningful post-compromise escalation primitive.
Privilege escalation via heap-based buffer overflow in the Windows DNS component affects Windows 10, Windows 11, and Windows Server editions spanning Server 2012 through Server 2025. An authorized local attacker holding low-privilege credentials can trigger the overflow to achieve full system compromise (C:H/I:H/A:H). No public exploit code or active exploitation has been identified at time of analysis; a vendor-released patch is available through the Microsoft Security Response Center advisory.
Heap-based buffer overflow in the Windows DNS component enables a locally authenticated low-privileged attacker to escalate privileges to SYSTEM across a broad range of Windows releases, from Windows 10 version 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. The CVSS 3.1 score of 7.8 reflects low attack complexity and full confidentiality, integrity, and availability impact once local access is obtained, with no user interaction required. No public exploit code or active exploitation has been identified at time of analysis, and a vendor-released patch is available via the Microsoft Security Response Center.
Heap-based buffer overflow in Microsoft Office (365 Apps for Enterprise, Office 2019, Office 2021 LTSC, and Office 2024 LTSC) enables a local attacker with low-privilege credentials to execute arbitrary code with the full confidentiality, integrity, and availability impact of the Office process. The vulnerability (CWE-122) carries a CVSS 3.1 score of 7.8 and requires only local access and a standard user account - no user interaction is needed once the attacker can trigger the vulnerable allocation path. No public exploit code has been identified at time of analysis, and SSVC assessment confirms current exploitation status as none.

Denial of service in Wireshark's C12.22 protocol dissector affects versions 4.6.0-4.6.7 and 4.4.0-4.4.17, where a malformed C12.22 packet triggers a heap buffer overflow (CWE-122) that crashes the application. An attacker who can get crafted traffic in front of a capturing or file-loading analyst can reliably terminate the dissection session. A proof-of-concept is reported via SSVC, but there is no evidence of active exploitation, and the EPSS probability is low (0.27%).
Heap buffer overflow in FreeRDP's Opus audio codec path allows a malicious RDP server to corrupt client heap memory and potentially execute arbitrary code on any connecting client built with WITH_OPUS enabled and WITH_DSP_FFMPEG disabled. The flaw in freerdp_dsp_decode_opus (versions prior to 3.28.0) stems from a capacity check applied to the wrong buffer, leaving the actual PCM output buffer unguarded against oversized libopus decoded frames that can overrun the fixed 4096-byte StreamPool_Take destination in the rdpsnd channel. No public exploit has been identified at time of analysis, but the confirmed heap write primitive and RCE classification make this a credible code execution risk for susceptible client builds connecting to untrusted servers.
Heap buffer overflow in FFmpeg's VC-2/Dirac RTP packetizer (libavformat/rtpenc_vc2hq.c) enables memory corruption via crafted Dirac data units across all versions prior to fix commit 1cdeb3c. The packetizer accepts an attacker-controlled data unit or fragment size and copies it into a fixed-size heap buffer without an upper-bound check, a classic CWE-122 condition with High confidentiality, integrity, and availability impact. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; an upstream fix commit is available from the FFmpeg repository.
Heap buffer overflow in FFmpeg's RIST protocol reader (libavformat/librist.c) lets a remote RIST sender corrupt heap memory in any FFmpeg instance ingesting an async:rist:// stream, enabling potential remote code execution or crash. The librist_read() function ignores the caller's buffer size and copies the entire received RIST payload into a destination buffer that the async wrapper sizes smaller than the packet, so an oversized payload writes past the buffer end. Reported by VulnCheck and fixed upstream in commit 1c10bcc; no public exploit is identified at time of analysis and it is not listed in CISA KEV.
Heap buffer overflow in FFmpeg's hvcC box writer exposes any version prior to commit acf5d7c to memory corruption during HEVC muxing. When a crafted HEVC file presents more NAL units of a single type than the count field can encode, integer overflow corrupts heap memory, potentially enabling arbitrary code execution in the FFmpeg process context. No public exploit has been identified at time of analysis and no CISA KEV listing exists, but server-side transcoding pipelines ingesting untrusted HEVC content effectively elevate the local-vector risk to a network-reachable attack surface.
Heap buffer overflows in FreeBSD's iconv(3) character-conversion library allow attackers who control input processed through the HZ, UTF-7, VIQR, or ZW encoding modules to corrupt heap memory, potentially leading to remote code execution. Applications on FreeBSD 14.3/14.4/15.0/15.1 that pass untrusted data through iconv using any of these encodings are exposed. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.21%, 12th percentile) despite the 9.8 CVSS.
Kernel memory corruption in FreeBSD's ZFS subsystem allows a local user with the delegated 'receive' ZFS permission to trigger a heap-based buffer overflow via the ZFS_IOC_RECV_NEW ioctl. The flaw stems from an integer truncation: a 64-bit payload size is silently narrowed to 32 bits for heap allocation, but the original 64-bit value is then used as the length for a subsequent byteswap operation - writing beyond the allocated buffer into kernel memory. Exploitation is limited to the heal receive path and requires the ZFS 'receive' delegation, but no patch has been publicly released yet for all affected branches. No public exploit code or CISA KEV listing has been identified at time of analysis.
Kernel heap overflow in FreeBSD's ZFS subsystem via the ZFS_IOC_USERSPACE_MANY ioctl enables local privilege escalation across multiple supported FreeBSD release branches. The flaw stems from an integer width mismatch: the kernel allocates a heap buffer sized by a 32-bit truncation of the caller-supplied 64-bit length, then copies records up to the original 64-bit limit - writing past the end of the allocation. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the low attack complexity and high impact across confidentiality, integrity, and availability make patching a priority for any FreeBSD deployment that uses ZFS delegated permissions.
