CVE-2026-45382
libde265 is an open source implementation of the h.265 video codec.
Overview
CVE-2026-45382 is a known-severity vulnerability. It was published on July 21, 2026.
Technical description
libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.19, `decoder_context::decode_slice_unit_tiles` (libde265/decctx.cc:920) reads `pps.CtbAddrRStoTS[ctbAddrRS]` at line 966 where `ctbAddrRS = ctbY * ctbsWidth + ctbX` is computed from PPS-supplied `colBd[]`/`rowBd[]` arrays without validating the result against `CtbAddrRStoTS.size() == sps->PicSizeInCtbsY`. A malformed PPS that passes `set_derived_values` but encodes geometry inconsistent with the SPS produces a `ctbAddrRS` past the allocation, causing a 4-byte heap-buffer-overflow READ. Version 1.0.19 fixes the issue.

How can CyberStrike help with CVE-2026-45382?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-45382 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
