Description OSIDB Bzimport 2025-05-01 15:02:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

9p: trans_fd/p9_conn_cancel: drop client lock earlier

syzbot reported a double-lock here and we no longer need this
lock after requests have been moved off to local list:
just drop the lock earlier.
