In the Linux kernel, the following vulnerability has been resolved:
raw: Fix a data-race around sysctl_raw_l3mdev_accept.
While reading sysctl_raw_l3mdev_accept, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader.

CVE-2022-49631 [MEDIUM] CWE-362 kernel: raw: Fix a data-race around sysctl_raw_l3mdev_accept.
kernel: raw: Fix a data-race around sysctl_raw_l3mdev_accept.
In the Linux kernel, the following vulnerability has been resolved:
raw: Fix a data-race around sysctl_raw_l3mdev_accept.
While reading sysctl_raw_l3mdev_accept, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader.
A flaw was found in the RAW-IP module in the Linux kernel. A race condition can occur when reading the sysctl_raw_l3mdev_accept resource due to a missing lock, potentially impacting system stability and resulting in a denial of service.
Statement: The RAW-IP module in the Linux kernel as shipped in Red Hat Enterprise Linux 8 is not affected by this vulnerability because the vulnerable code was introduced in a newer version of the Linux kernel.
This issue has been fixed in Red Hat Enterpri
