{"id":"CVE-2026-80747","summary":"drm/amdkfd: Add bounds check for CRAT subtype length","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: Add bounds check for CRAT subtype length\n\nThe CRAT parser validates that the subtype header fits within the image,\nbut does not verify that the advertised subtype length fits. A malformed\nCRAT table with an oversized length field causes out-of-bounds reads when\nkfd_parse_subtype() casts the header to specific subtype structures.\n\nAdd validation that sub_type_hdr + length does not exceed the image\nboundary before parsing the subtype contents.\n\n(cherry picked from commit 48e1d1e6e8798aef0312e68d8e586021b5b3cf4d)","modified":"2026-09-05T03:48:34.727658716Z","published":"2026-09-03T08:26:28.938Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80747.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6e7566ba4739dd573c331adde1c96690f7a567bd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca91e0cc8087568e4b791648a7c01e804f48cb73"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80747.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80747"},{"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":"5b5c4e40a37e858e2bff8cd91be8e972256392c4"},{"fixed":"ca91e0cc8087568e4b791648a7c01e804f48cb73"},{"fixed":"6e7566ba4739dd573c331adde1c96690f7a567bd"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80747.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.19.0"},{"fixed":"7.1.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80747.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H"}]}
