CVE-2026-89601

A flaw was found in the Linux kernel's ext2 filesystem. This vulnerability occurs in the ext2setsize and ext2xattrset2 functions, where inode updates for ISSYNC inodes may be lost. This happens because the syncinodemetadata function only processes inodes that are already marked as dirty, leading ...

CVE-2026-89601

This vulnerability affects the Linux kernel ext2 filesystem in the ext2_setsize() and ext2_xattr_set2() functions. The root cause is that for IS_SYNC inodes , sync_inode_metadata() is called without first marking the inode dirty; since that function only operates on already-dirty inodes, inode up...
