CVE-2026-55373 OpenEXR: OpenEXRUtil SampleCountChannel endEdit() can loop forever on UINT_MAX sample counts

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. Versions prior to 3.2.10, 3.3.12, and 3.4.13 contain an infinite-loop vulnerability in SampleCountChannel. The helper roundListSizeUp rounds a sample-list size up to the...

Heap Buffer Overflow in CMS Key Unwrapping

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that query reports, causing an 8-byte out-of-bounds heap write. Impact summary: An attacker who supplies a...

PT-2026-81461

Name of the Vulnerable Software and Affected Versions OpenEXR versions prior to 3.2.11 OpenEXR versions 3.3.0 through 3.3.12 OpenEXR versions 3.4.0 through 3.4.13 Description On ILP32 builds, an out-of-bounds read occurs when processing a crafted uncompressed deep-tile EXR. This happens because t...

Astra Linux – Vulnerability in krb5

In MIT Kerberos 5 also known as krb5, before version 1.21.3, an attacker could modify the plaintext Extra Count field of a confidential GSS krb5 wrap token. This modification caused the unwrapped token to appear truncated, affecting the application...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: iomap: added protection against concurrent truncate and underflow operations. iomap: fixed the issue where zero-padding occurred during concurrent append writes. The accounting of ioend was changed so that iosize only tracks...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/ipv6: ioam6: This vulnerability prevents a wrap-around issue with the schema length during the trace filling process. The ioam6fillTraceData function stores the schema contribution to the trace length in an u8 type variable...

Astra Linux – Vulnerability in libvpx

There are integer overflows in the libvpx library in versions prior to 1.14.1. Calling vpximgalloc with a large value of the dw, dh, or align parameter may lead to integer overflows in the calculations of buffer sizes and offsets, and some fields of the returned vpximaget struct may become invali...

SUSE CVE-2026-72854

EUVD-2026-64138

GNU Emacs before 31.0.91 contains an integer overflow in the PBM/PPM/PGM image loader that allows an attacker to leak heap memory contents by supplying a crafted image with large dimensions and an elevated max color index. The image loader multiplies image dimensions and channel count using signe...

CVE-2026-75147

FFmpeg versions before commit 983dae9 have an out-of-bounds read in the AV1 RTP packetizer (libavformat/rtpenc_av1.c). A crafted OBU size causes the remaining-size counter to wrap, letting the keyframe-detection loop dereference a pointer past the packet buffer. CVSS 3.1 scores 7.1 (HIGH). No in-...

CVE-2026-58087 Heap out-of-bounds access in semctl(2)

The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...

CVE-2026-58087

CVE-2026-58087 is a heap out-of-bounds access in the GETALL and SETALL commands of FreeBSD's semctl(2) system call. The root cause is a sequence-number wrap after 0x8000 create/destroy cycles: an unprivileged local user can rapidly destroy and recreate semaphore sets at the same index, causing a ...
