CVE-2026-68245

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