Description OSIDB Bzimport 2025-07-25 14:02:38 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: ath6kl: remove WARN on bad firmware input

If the firmware gives bad input, that's nothing to do with
the driver's stack at this point etc., so the WARN_ON()
doesn't add any value. Additionally, this is one of the
top syzbot reports now. Just print a message, and as an
added bonus, print the sizes too.
