libde265 vulnerabilities
4 known CVE vulnerabilities in libde265, translated and rated.
- CVE-2025-61147Low
A segmentation fault was discovered in the libde265 library (commit d9fea9d) in the decoder_context::compute_framedrop_table() function. This vulnerability may cause crashes in applications using this library.
- CVE-2026-45383Medium
Vulnerability in the libde265 library (H.265 codec implementation) prior to version 1.0.19. A heap buffer overflow (out-of-bounds READ) exists in `decoder_context::decode_slice_unit_WPP()` that can be triggered by crafted HEVC streams with WPP, leading to crashes or potentially code execution.
- CVE-2026-45382Medium
In libde265 prior to version 1.0.19, there is a heap-buffer-overflow read vulnerability. The flaw in `decoder_context::decode_slice_unit_tiles` allows reading 4 bytes past the allocated buffer via malformed PPS data.
- CVE-2026-49337Medium
libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes `decoder_context::read_slice_NAL()` to attach slice headers to a finished picture object that has no active image unit, resulting in attacker-controlled unbounded heap growth.
