CVE-2023-54006

CVE-2023-54006 affects the Linux kernel af_unix path. It is a data race where unix_tot_inflight is written under a spin_lock but read locklessly by unix_release_sock; the fix is to use READ_ONCE() for unix_tot_inflight. The description (and multiple advisories) indicate a KCSAN-detected race betw...
