Description OSIDB Bzimport 2025-02-26 03:21:00 UTC 
In the Linux kernel, the following vulnerability has been resolved:

icmp: Fix a data-race around sysctl_icmp_errors_use_inbound_ifaddr.

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