In the Linux kernel, the following vulnerability has been resolved:
icmp: Fix data-races around sysctl.
While reading icmp sysctl variables, they can be changed concurrently.
So, we need to add READ_ONCE() to avoid data-races.

CVE-2022-49638 [MEDIUM] CWE-362 kernel: icmp: Fix data-races around sysctl.
kernel: icmp: Fix data-races around sysctl.
In the Linux kernel, the following vulnerability has been resolved:
icmp: Fix data-races around sysctl.
While reading icmp sysctl variables, they can be changed concurrently.
So, we need to add READ_ONCE() to avoid data-races.
A flaw was found in the Linux kernel's ICMP protocol. A race condition can occur when reading the ICMP sysctl variables due to a missing lock, potentially impacting system stability and resulting in a denial of service.
Statement: This issue has been fixed in Red Hat Enterprise Linux 9.2 via RHSA-2023:2458 [1].
