{"id":"AZL-108185","summary":"CVE-2026-98413 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: always fill AVC decision in avc_has_perm_noaudit()\n\navc_has_perm_noaudit() is documented to return a copy of the access\ndecision in @avd, but its early return for an empty requested permission\nset leaves the buffer untouched.  All callers pass an uninitialized\nstack variable and afterwards feed it to avc_audit(), and the inode hook\neven stores it in the per-task decision cache.\n\nFill in a deny-all, audit-all decision, similar to avd_init(), so every\ncaller receives a defined value at no cost on the hot path.","modified":"2026-10-15T14:17:16.458151511Z","published":"2026-10-14T14:17:52Z","upstream":["CVE-2026-98413"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98413"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-108185.json"}}],"schema_version":"1.9.0"}
