In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: fix a possible null-pointer dereference due to data race in sndhdacregmapsync The variable codec-regmap is often protected by the lock codec-regmaplock when is accessed. However, it is accessed without holding the lock...

kernel: bpf: Address KCSAN report on bpf_lru_list

A data race was found in the BPF LRU list implementation. Concurrent access to node-ref without proper memory barriers triggers KCSAN warnings, though the race is benign as the reference value does not need to be precise...

kernel: af_unix: Fix data-race around unix_tot_inflight

A data race condition was found in the Linux kernel's AFUNIX socket implementation. The unixtotinflight variable is modified under spinlockunixgclock but read without synchronization in unixreleasesock. This was detected by KCSAN Kernel Concurrency Sanitizer. The fix adds READONCE to ensure prope...
