Once xa_unlock_irqrestore is\ncalled and returned, the pointer is no longer under lock and is subject\nto modification. Since, the caller still dereferences vm->task_info in\namdgpu_vm_get_task_info_vm() after the lock is removed, this causes a\nuse after unlock problem.\n\nRemove the lifetime issue present in amdgpu_vm_get_task_info_pasid()\nthrough removing the amdgpu_vm_get_vm_from_pasid() function from\namdgpu_vm.c and making the relevant code inline to hold the lock while\nit is still in use.\n\n(cherry picked from commit 9d01579f3f868b333acc901815972685989092c7)\n\n## Affected\n\n- `Linux >= b8f67b9ddf4f8fe6dd536590712b5912ad78f99c < fe16a7e5336ae888751984e30c451fbf7cfa5df7`\n- `Linux >= b8f67b9ddf4f8fe6dd536590712b5912ad78f99c < 1173190412fb9d12e7efce76734118d9712ff970`\n- `Linux >= b8f67b9ddf4f8fe6dd536590712b5912ad78f99c < 5d5fb9124a2bba96a7807086d8fe0f7ce810d546`\n- `Linux >= b8f67b9ddf4f8fe6dd536590712b5912ad78f99c < 04cc4aa3617b0ed67e859f91f09de5d896a46f3a`\n- `Linux 6.9`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
