Attackers can supply a crafted VVC bitstream activating a new SPS with sps_ref_wraparound_enabled_flag set, causing reads from missing PIC_RECON_WRAP buffers and denial of service.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.8,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794061073095,"publishedAt":1794061073095,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/fraunhoferhhi/vvdec/issues/420"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/fraunhoferhhi/vvdec/commit/fb73aca37b48f89814f57edbc8072a37d47bbe06"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/InterPrediction.cpp#L790-L796"},{"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-null-pointer-dereference-via-interprediction-xpredinterblk"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
