Summary
CVE-2022-49576 is a data race vulnerability affecting the Linux kernel's ipv4 subsystem. Specifically, a race condition existed between reading and modifying the value of sysctl_fib_multipath_hash_fields. This issue could lead to unintended system behavior or even security vulnerabilities, as the value could be changed concurrently while being read. To mitigate this risk, the Linux kernel developers added the READ_ONCE() synchronization primitive to prevent data races for this variable.
