CVE-2026-31694

In the Linux kernel, the following vulnerability has been resolved: fuse: reject oversized dirents in page cache fuseadddirenttocache computes a serialized dirent size from the server-controlled namelen field and copies the dirent into a single page-cache page. The existing logic only checks...

CVE-2026-31694

Summary: CVE-2026-31694 fixes a Linux kernel FUSE directory-entry handling flaw. A malicious FUSE server could cause a 24-byte overflow by returning a dirent whose serialized size (based on namelen) exceeds a single PAGE_SIZE. The bug arises in fuse_add_dirent_to_cache(), which previously only ch...

CVE-2026-31465

CVE-2026-31465 in the Linux kernel concerns the writeback path for filesystems without data integrity guarantees (e.g., fuse). The fix adds a SB_I_NO_DATA_INTEGRITY superblock flag; when set, sync kicks off writeback of dirty inodes but does not wait for flusher threads to finish. The change move...
