CVE-2026-12844 1 Drolsky 1 List::someutils::xs 2026-06-26 7.5 High
List::SomeUtils::XS versions before 0.59 for Perl have a heap buffer overflow in the pairwise function. pairwise() collects the values returned by the block into a heap buffer sized to the longer input array, then grows the buffer before each copy with a single quadrupling (alloc <<= 2) instead of a loop. A block call that returns more than four times the current allocation in one invocation outgrows that one quadrupling, and the copy writes past the end of the buffer. Any caller of pairwise() whose block returns, for a single pair, more than four times the longer input array's length writes past the buffer and corrupts the heap.
CVE-2026-56789 2 Rtklib, Tomojitakasu 2 Rtklib, Rtklib 2026-06-26 6.5 Medium
RTKLIB through 2.4.3 contains a heap buffer overflow vulnerability in the readrnxobsb function in src/rinex.c that allows attackers to trigger memory corruption by failing to clamp satellite count values from RINEX epoch headers. Attackers can craft malicious RINEX files declaring more than 64 satellites per epoch to cause heap buffer overflow writes and out-of-bounds stack reads, crashing RTKLIB-based applications including rnx2rtkp and RTKPOST.
CVE-2026-46752 1 Apache 1 Kvrocks 2026-06-26 N/A
Redis Lua HEAP overflow in cjson library vulnerability in Apache Kvrocks. This issue affects Apache Kvrocks: from 2.0.4 through 2.15.0. Users are recommended to upgrade to version 2.16.0, which fixes the issue.
CVE-2026-9088 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-06-26 2.7 Low
A flaw was found in org.keycloak.services. An administrator with delegated access to read group memberships and users can bypass user profile permissions by accessing the group members endpoint. This allows the administrator to view user attributes that are explicitly configured to be denied, leading to information disclosure.
CVE-2025-31177 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-25 5.5 Medium
gnuplot is affected by a heap buffer overflow at function utf8_copy_one.
CVE-2025-60468 1 Gpac 2 Gpac, Mp4box 2026-06-25 5.5 Medium
GPAC Multimedia Open Source Project GPAC Project/MP4Box 2.5-DEV-rev1593-gfe88c3545-master is affected by: Buffer Overflow. The impact is: cause a denial of service (local). The component is: filter_core/filter_pid.c (L:574-580): function gf_filter_pid_inst_swap_delete_task() improperly accesses freed objects during PID instance swap/delete cleanup, leading to heap use-after-free. The attack vector is: Local (AV:L): a local, authenticated user who processes a specially crafted MPEG-2 TS/MP4 file with MP4Box can trigger the bug during filter teardown (PID instance swap/delete), causing a crash. ¶¶ In GPAC s MP4Box, gf_filter_pid_inst_swap_delete_task() in filter_core/filter_pid.c may dereference objects after they have been freed when cleaning up PID instances after a swap/delete operation. Crafted inputs (e.g., malformed MPEG-2 TS) can trigger a heap use-after-free and crash; exploitation may be possible.
CVE-2026-2050 1 Gimp 1 Gimp 2026-06-25 7.8 High
GIMP HDR File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of HDR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28266.
CVE-2026-12244 1 Nlnetlabs 1 Nsd 2026-06-25 8.8 High
If NSD is configured as secondary for a zone, the primary of that zone can crash NSD with an AXFR containing a DNS message with a special crafted SVCB RR with an rdata size of 65512, that let's an (uint16_t) variable that is used to allocate space needed for the RR wrap (because total size > 65535), causing a heap overflow. The attacker can perform a controlled (RCE class) head write of up to 65509 bytes
CVE-2026-12725 3 Dnsmasq, Redhat, Thekelleys 5 Dnsmasq, Enterprise Linux, Openshift and 2 more 2026-06-24 5.9 Medium
A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply such a DNS response may crash the dnsmasq process, resulting in denial of service.
CVE-2026-45696 2 Academysoftwarefoundation, Openexr 2 Openexr, Openexr 2026-06-24 6.5 Medium
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.11, the HTJ2K (High-Throughput JPEG 2000) decoder, ht_undo_impl() in OpenEXRCore is vulnerable to a heap-buffer-overflow READ. The ht_undo_imp function copies decoded pixels out of a per-line OpenJPH buffer using the EXR channel's declared width as the iteration count. The codestream embedded in the EXR chunk can declare different (smaller) tile/line dimensions than the EXR header advertises, but ht_undo_impl() does not validate this — it pulls width 32-bit samples from cur_line->i32[] without checking the OpenJPH line buffer's actual length. A crafted EXR file produces a 4-byte heap-buffer-overflow READ immediately after a buffer allocated by ojph::local::codestream::finalize_alloc(). The bug is reachable through the standard scanline-decode entry point used by every consumer of exr_decoding_run/Imf::checkOpenEXRFile, including thumbnailers, asset pipelines, and the exrcheck utility — i.e. any application that opens untrusted EXR files. The result is a deterministic crash (DoS) and potential adjacent-heap leak. This issue has been fixed in version 3.4.12.
CVE-2026-54517 1 Fasterxml 1 Jackson-databind 2026-06-24 5.3 Medium
jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, in BeanDeserializer._deserializeUsingPropertyBased, the active-view (@JsonView) filter was applied only to creator properties; the regular property-buffering branch performed no prop.visibleInView(activeView) check. A change making SetterlessProperty.isMerging() return true routed setterless Collection/Map properties through this unguarded path, so a setterless collection annotated with a restricted @JsonView is populated from attacker JSON even when the active view excludes it. This vulnerability is fixed in 2.21.4 and 3.1.4.
CVE-2026-45475 1 Microsoft 15 365 Apps, Microsoft 365, Microsoft 365 Apps For Enterprise and 12 more 2026-06-24 7.8 High
Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally.
CVE-2026-8484 1 Fusesource 1 Jansi 2026-06-23 N/A
A heap buffer overflow vulnerability exists in the Jansi JNI "ioctl()" wrapper due to a lack of size verification for the argument array before the system call. This can lead to heap corruption and application crashes (DoS). All versions are believed to be vulnerable. This project is unmaintained at the time of CVE assignment.
CVE-2026-47749 1 Leejet 1 Stable-diffusion.cpp 2026-06-23 7.8 High
stable-diffusion.cpp is a pure C/C++ library for running diffusion model (Stable Diffusion, Flux, Wan, Qwen Image, Z-Image, and more) inference. Versions prior to master-584-0a7ae07 are vulnerable to heap buffer overflow in SHORT_BINUNICODE parsing for PyTorch checkpoint files. The pickle .ckpt parser in src/model.cpp contained a heap buffer overflow vulnerability in the SHORT_BINUNICODE opcode handler. The issue was caused by sign confusion on the opcode length field. A crafted .ckpt file could trigger memcpy with a very large length derived from a negative signed value, causing immediate heap corruption. Any application using affected stable-diffusion.cpp releases to load untrusted .ckpt model files could be vulnerable. A malicious checkpoint file could cause heap corruption through memcpy with an attacker-controlled length. This may lead to process crash and could potentially be leveraged for code execution depending on heap layout. The attack requires the victim or application to load a .ckpt file from an untrusted source, such as a downloaded model from a model sharing site. The issue has been resolved in version master-584-0a7ae07. If developers are unable to immediately update their applications they can work around this issue by not loading .ckpt checkpoint files from untrusted sources, and referring to trusted model sources and safer formats such as .safetensors where possible.
