NVD Description

Note: Versions mentioned in the description apply only to the upstream bpftool package and not the bpftool package as distributed by RHEL.

In the Linux kernel, the following vulnerability has been resolved:

ipv4: Fix data-races around sysctl_fib_multipath_hash_fields.

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