CVE-2026-45915

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

Description Corrupted FAT images can cause a directory inode to have an incorrect i nlink value. When the rmdir operation is performed, it unconditionally calls the drop nlink() function, which can reduce i nlink to 0 and trigger a warning. This issue is addressed by implementing sanity checks in the vfat rmdir() and msdos rmdir() functions to ensure the parent link count is only dropped when it is at least 3; otherwise, a filesystem error is reported.

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