{"id":"CVE-2026-68229","summary":"media: cedrus: skip invalid H.264 reference list entries","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: cedrus: skip invalid H.264 reference list entries\n\nCedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the\nstateless slice control and later uses their indices to look up\ndecode-\u003edpb[] in _cedrus_write_ref_list().\n\nRejecting such controls in cedrus_try_ctrl() would break existing\nuserspace, since stateless H.264 reference lists may legitimately carry\nout-of-range indices for missing references. Instead, guard the actual\nDPB lookup in Cedrus and skip entries whose indices do not fit the fixed\nV4L2_H264_NUM_DPB_ENTRIES array.\n\nThis keeps the fix local to the driver use site and avoids out-of-bounds\nreads from malformed or unsupported reference list entries.","modified":"2026-08-21T03:30:24.446498018Z","published":"2026-08-10T12:00:51.935Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68229.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0af8945fcae742d099f59f3c725eb67235953a31"},{"type":"WEB","url":"https://git.kernel.org/stable/c/10358ea986c3c85516d1c8206486464f79d36e76"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1db34683b0fbbcb3bc162380c11514ea0a44e8ab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ee8327c85b3ac7b532d2d6a1e3a295d5ad7414a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7ff6f728a2433b420bb372cb0e8a4eea3f2e1a4b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9924cb548ee7753a6473997949c3ec48092de0b0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a6a109771c51920beb620f30778c29da823cc34c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e53112c2de88982e66c369aee2120d5efd78df30"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68229.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68229"},{"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":"e000e1fa4bdbd783149e7f97cf3be61e1c0bab8c"},{"fixed":"a6a109771c51920beb620f30778c29da823cc34c"},{"fixed":"7ff6f728a2433b420bb372cb0e8a4eea3f2e1a4b"},{"fixed":"1db34683b0fbbcb3bc162380c11514ea0a44e8ab"},{"fixed":"2ee8327c85b3ac7b532d2d6a1e3a295d5ad7414a"},{"fixed":"0af8945fcae742d099f59f3c725eb67235953a31"},{"fixed":"9924cb548ee7753a6473997949c3ec48092de0b0"},{"fixed":"e53112c2de88982e66c369aee2120d5efd78df30"},{"fixed":"10358ea986c3c85516d1c8206486464f79d36e76"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68229.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.265"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.216"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68229.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"}]}
