CVE-2026-89601

8.8 high Published
NVD · CVE.org

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().

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
