{"id":"AZL-96249","summary":"CVE-2026-74450 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/pm: fix pptable use-after-free\n\namdgpu_dpm_get_pp_table() returns a pointer to a driver-owned power table\nafter dropping adev-\u003epm.mutex. The sysfs path then copies from that pointer.\nA concurrent pp_table write can replace and free the allocation during the\ncopy, causing a use-after-free.\n\nChange the DPM interface to copy into caller-provided storage while the mutex\nis held. Keep the size-only query for attribute discovery without exposing\nthe driver-owned pointer.\n\n(cherry picked from commit f6eed7acfd30099ef7baeb6ba45bb59daad80631)","modified":"2026-08-31T05:26:27Z","published":"2026-08-15T13:17:49Z","upstream":["CVE-2026-74450"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74450"}],"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-96249.json"}}],"schema_version":"1.9.0"}
