Attackers can craft a VVC bitstream enabling TMVP with a smaller collocated reference picture, causing getColInfo to read past the colMotion allocation when error concealment is enabled.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.7,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":4.7,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794061073762,"publishedAt":1794061073762,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/fraunhoferhhi/vvdec/issues/422"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/fraunhoferhhi/vvdec/commit/0695c06221c27b3680fec9851ac2cf46b2195ea9"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/Slice.cpp#L1819-L1859"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/CodingStructure.cpp#L453-L458"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/fraunhoferhhi/vvdec"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/fraunhofer-hhi-vvdec-through-3.2.1-heap-out-of-bounds-read-via-codingstructure-getcolinfo"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
