Vulnerability in Linux kernel (CVE-2025-71314)

Summary

Vulnerability in Linux kernel (CVE-2025-71314). Risk of unauthorized operations or information disclosure.

Original description

The description as published by the source.

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
