Description OSIDB Bzimport 2024-10-21 12:01:10 UTC

In the Linux kernel, the following vulnerability has been resolved:

sock_map: Add a cond_resched() in sock_hash_free()

Several syzbot soft lockup reports all have in common sock_hash_free()

If a map with a large number of buckets is destroyed, we need to yield
the cpu when needed.
