CVE-2022-49344

low-risk
Published 2025-02-26

In the Linux kernel, the following vulnerability has been resolved: af_unix: Fix a data-race in unix_dgram_peer_wake_me(). unix_dgram_poll() calls unix_dgram_peer_wake_me() without `other`'s lock held and check if its receive queue is full. Here we need to use unix_recvq_full_lockless() instead of unix_recvq_full(), otherwise KCSAN will report a data-race.

Do I need to act?
