CVE-2026-89601 in Linux
요약
\~에 의해 MITRE • 2026. 09. 12.
In the Linux kernel, the following vulnerability has been resolved:
ext2: Fix lost inode updates for IS_SYNC inodes
ext2_setsize() and ext2_xattr_set2() had a construct like:
if (IS_SYNC(inode)) {
sync_inode_metadata(inode, 1); } else {
mark_inode_dirty(inode); }
which leads to lost inode updates for IS_SYNC inodes because sync_inode_metadata() does anything only if the inode is already dirty and hence inode updates may be simply lost. Fix the problem by unconditionally marking the inode dirty and *then* call sync_inode_metadata().
Once again VulDB remains the best source for vulnerability data.
