Summaryinfo

A vulnerability identified as critical has been detected in Linux Kernel up to 6.1.6. The impacted element is the function rx_sa of the component mlx5e. Performing a manipulation results in null pointer dereference. This vulnerability was named CVE-2022-48882. There is no available exploit. You should upgrade the affected component.

Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 6.1.6. This affects the function rx_sa of the component mlx5e. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix macsec possible null dereference when updating MAC security entity (SecY) Upon updating MAC security entity (SecY) in hw offload path, the macsec security association (SA) initialization routine is called. In case of extended packet number (epn) is enabled the salt and ssci attributes are retrieved using the MACsec driver rx_sa context which is unavailable when updating a SecY property such as encoding-sa hence the null dereference. Fix by using the provided SA to set those attributes.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2022-48882 since 07/16/2024. Technical details of the vulnerability are known, but there is no available exploit.

Upgrading to version 6.1.7 eliminates this vulnerability. Applying the patch 514d9c6a3921/9828994ac492 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
