CVE-2022-49631

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A data-race issue exists around sysctl raw l3mdev accept. The value of sysctl raw l3mdev accept can be changed concurrently while it is being read, which may lead to unpredictable behavior. To address this, the use of READ ONCE() is recommended for its reader.

Recommendations For the Linux kernel, consider adding READ ONCE() to the reader of sysctl raw l3mdev accept to prevent concurrent modifications. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
