Summary

CVE-2022-49596 is a vulnerability affecting the Linux kernel's TCP stack. This issue involves a data race during the reading of sysctl_tcp_min_snd_mss. Concurrent changes to this value while it's being read can result in incorrect data being processed. To mitigate this risk, the Linux kernel developers have introduced the READ_ONCE() macro to ensure that readers access consistent data. This measure prevents potential data corruption and maintains the stability of the TCP stack.
