CVE-2026-68245
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix lifetime issue of amdgpu_vm_get_task_info_pasid()
The vm pointer returned from amdgpu_vm_get_vm_from_pasid() is only
valid while the lock is still being held. Once xa_unlock_irqrestore is
called and returned, the pointer is no longer under lock and is subject
to modification. Since, the caller still dereferences vm->task_info in
amdgpu_vm_get_task_info_vm() after the lock is removed, this causes a
use after unlock problem.
Remove the lifetime issue present in amdgpu_vm_get_task_info_pasid()
through removing the amdgpu_vm_get_vm_from_pasid() function from
amdgpu_vm.c and making the relevant code inline to hold the lock while
it is still in use.
(cherry picked from commit 9d01579f3f868b333acc901815972685989092c7)
