- Summary
- CVE-2026-74450 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix pptable use-after-free
amdgpudpmgetpptable() returns a pointer to a driver-owned power table after dropping adev->pm.mutex. The sysfs path then copies from that pointer. A concurrent pp_table write can replace and free the allocation during the copy, causing a use-after-free.
Change the DPM interface to copy into caller-provided storage while the mutex is held. Keep the size-only query for attribute discovery without exposing the driver-owned pointer.
(cherry picked from commit f6eed7acfd30099ef7baeb6ba45bb59daad80631)
