CVE-2025-71314

None

No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Recover from panthor gpu flush caches() failures
We have seen a few cases where the whole memory subsystem is blocked and flush operations never complete. When that happens, we want to:
  • schedule a reset, so we can recover from this situation
  • in the reset path, we need to reset the pending reqs so we can send new commands after the reset
  • if more panthor gpu flush caches() operations are queued after the timeout, we skip them and return -EIO directly to avoid needless waits (the memory block won't miraculously work again)
Note that we drop the WARN ON()s because these hangs can be triggered with buggy GPU jobs created by the UMD, and there's no way we can prevent it. We do keep the error messages though.
v2:
  • New patch
v3:
  • Collect R-b
  • Explicitly mention the fact we dropped the WARN ON()s in the commit message
v4:
  • No changes
