CVE-2026-89266

stb_vorbis (a single-file C library for Vorbis audio decoding) contains a heap buffer overflow in start_decoder() affecting versions through 1.22 . The root cause is a truncation of the codebook multiplicands allocation size from size_t to int, allowing a crafted Ogg Vorbis file with large entrie...

CVE-2026-89266

stbvorbis through 1.22 contains a heap buffer overflow in startdecoder where the codebook multiplicands allocation size is truncated from sizet to int. Attackers can craft a malicious Ogg Vorbis file with large entries and dimensions values to trigger out-of-bounds writes, causing process crashes...

CVE-2026-54241

libde265 , an open-source H.265/HEVC video codec, is affected by a signed 32-bit integer overflow in the SAO (Sample Adaptive Offset) sequential filter input-buffer size calculation. A crafted HEVC stream with large dimensions and 16-bit luma samples causes an undersized allocation, leading to an...

CVE-2026-54241 libde265: SAO sequential filter heap buffer overflow via signed integer overflow

libde265 is an open source implementation of the h.265 video codec. Versions prior to 1.1.1 use signed 32-bit arithmetic to calculate the sample adaptive offset input-buffer size, allowing a crafted HEVC stream with large dimensions and 16-bit luma samples to cause an integer overflow, an...

CVE-2026-89620

A flaw was found in the Linux kernel's HID Intel QuickSPI driver. A local attacker can exploit a heap buffer overflow by providing a specially crafted report through a hidraw SETREPORT/SETFEATURE ioctl. This allows the attacker to overflow a buffer with controlled length and content, potentially...
