{"id":"AZL-99041","summary":"CVE-2026-80747 affecting package kernel 6.6.150.1-1","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":"2026-09-06T05:31:44Z","published":"2026-09-03T13:06:14Z","upstream":["CVE-2026-80747"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80747"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99041.json"}}],"schema_version":"1.9.0"}
