Description OSIDB Bzimport 2025-02-26 03:02:39 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ipv4: Fix a data-race around sysctl_fib_multipath_use_neigh.

While reading sysctl_fib_multipath_use_neigh, it can be changed
concurrently.  Thus, we need to add READ_ONCE() to its reader.
