Description OSIDB Bzimport 2025-02-26 03:19:48 UTC 
In the Linux kernel, the following vulnerability has been resolved:

icmp: Fix data-races around sysctl_icmp_echo_enable_probe.

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