CVE-2026-45382

A flaw was found in libde265, an open-source implementation of the H.265 video codec. A remote attacker could exploit this by providing a malformed H.265 video stream. Processing this malformed data can lead to a heap-buffer-overflow read, which may cause a denial of service DoS by crashing the...

CVE-2026-45383

A flaw was found in libde265, an open-source implementation of the H.265 video codec. A remote attacker could exploit a heap buffer overflow vulnerability by providing specially crafted video files. This occurs when decoding a Wavefront Parallel Processing WPP HEVC slice, where malformed headers...

CVE-2026-45383

libde265 is an open source implementation of the h.265 video codec. Versions prior to 1.0.19 have a heap buffer overflow out-of-bounds READ exists in decodercontext::decodesliceunitWPP in libde265/decctx.cc. When decoding a WPP Wavefront Parallel Processing HEVC slice, ctbAddrRS is computed as...

CVE-2026-45382

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.19, decodercontext::decodesliceunittiles libde265/decctx.cc:920 reads pps.CtbAddrRStoTSctbAddrRS at line 966 where ctbAddrRS = ctbY ctbsWidth + ctbX is computed from PPS-supplied colBd/rowBd arrays without...

CVE-2026-45383

CVE-2026-45383 affects libde265 prior to 1.0.19, where a heap-buffer-overflow can occur during HEVC WPP slice decoding. In decoder_context::decode_slice_unit_WPP(), ctbAddrRS is computed as ctbRow*ctbsWidth and, if PPS/SPS headers encode a value that exceeds pps.CtbAddrRStoTS.size(), an out-of-bo...

CVE-2026-45382

libde265 prior to v1.0.19 contains a heap-buffer-overflow read in decode_slice_unit_tiles caused by unvalidated PPS tile geometry (ctbAddrRS computed from PPS colBd/rowBd without ensuring it fits CtbAddrRStoTS.size() == sps-&gt;PicSizeInCtbsY). A malformed PPS that passes set_derived_values but e...
