Name of the Vulnerable Software and Affected Versions Linux kernel versions 6.2 through 6.10

Description A flaw exists in the Linux kernel related to the xfs file system. Specifically, the xchk scrub create subord function did not correctly handle error conditions, potentially returning an invalid value instead of NULL. Callers of this function were also not checking for a NULL pointer, leading to potential issues. The corrections were applied to code merged between kernel versions 6.2 and 6.10.

Recommendations Update to a version later than 6.10. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
