Description OSIDB Bzimport 2025-10-07 16:05:21 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: ath6kl: reduce WARN to dev_dbg() in callback

The warn is triggered on a known race condition, documented in the code above
the test, that is correctly handled.  Using WARN() hinders automated testing.
Reducing severity.
