{"id":"CVE-2026-43310","summary":"media: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC\n\nFor the i.MX8MQ platform, there is a hardware limitation: the g1 VPU and\ng2 VPU cannot decode simultaneously; otherwise, it will cause below bus\nerror and produce corrupted pictures, even potentially lead to system hang.\n\n[  110.527986] hantro-vpu 38310000.video-codec: frame decode timed out.\n[  110.583517] hantro-vpu 38310000.video-codec: bus error detected.\n\nTherefore, it is necessary to ensure that g1 and g2 operate alternately.\nThis allows for successful multi-instance decoding of H.264 and HEVC.\n\nTo achieve this, g1 and g2 share the same v4l2_m2m_dev, and then the\nv4l2_m2m_dev can handle the scheduling.","modified":"2026-07-08T08:13:28.057859023Z","published":"2026-05-08T13:11:28.372Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43310.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/286d629d10640bc22f3bf46aa4f356eb7975e862"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0203ddf9af7c8e170e1e99ce83b4dc07f0cd765"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43310.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43310"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cb5dd5a0fa518dff14ff2b90837c3c8f98f4dd5c"},{"fixed":"286d629d10640bc22f3bf46aa4f356eb7975e862"},{"fixed":"e0203ddf9af7c8e170e1e99ce83b4dc07f0cd765"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43310.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43310.json"}}],"schema_version":"1.7.5"}
