  "summary": "drm/amd/pm: fix pptable use-after-free",
  "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->pm.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)",
