CVE-2026-89601

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

Description An issue exists in the ext2 file system where inode updates may be lost for IS SYNC inodes. This occurs within the ext2 setsize() and ext2 xattr set2() functions because sync inode metadata() only performs actions if the inode is already marked as dirty. If the inode is not dirty, the update is lost.

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