EUVD-2026-76760

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 pixel offsets, allowing a crafted HEVC stream with large image dimensions to trigger an integer overflow and cause out-of-bounds heap reads or writes, potentially...

CVE-2026-54240

libde265 , an open-source H.265/HEVC video codec library, is affected by a signed integer overflow in its pixel accessor. Versions prior to 1.1.1 use signed 32-bit arithmetic to compute pixel offsets; a crafted HEVC stream with large image dimensions can overflow this value, causing out-of-bounds...

CVE-2026-54241: Heap-based Buffer 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...
