Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the XFS file system related to the handling of ENODATA errors. Specifically, the code does not properly differentiate between ENODATA errors originating from disk I/O and those expected within the xattr (extended attribute) code. This can lead to incorrect error reporting to userspace, potentially indicating an attribute is not found when a disk I/O error has occurred. In certain scenarios, this can also cause a kernel oops due to a null pointer dereference in the
xfs attr leaf get() function. Prior to commit 07120f1abdff, the kernel did not oops but returned an incorrect error code to userspace.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
