CVE-2026-92502 ext4: clear stale xarray tags on folios skipped during writeback

In the Linux kernel, the following vulnerability has been resolved: ext4: clear stale xarray tags on folios skipped during writeback In data=journal mode, the writeback thread can hit the WARNONONCEsbrdonlysb in ext4journalcheckstart while the superblock is being remounted read-only during reboot...

CVE-2026-92502

CVE-2026-92502 affects the ext4 filesystem in the Linux kernel when using data=journal mode. The root cause is that folio_clear_dirty_for_io clears the PG_dirty flag but leaves the PAGECACHE_TAG_DIRTY and PAGECACHE_TAG_TOWRITE xarray tags set. In data=journal mode, jbd2 checkpoints journalled dat...

CVE-2026-92501

CVE-2026-92501 is a race condition in the Linux kernel's ext4 filesystem, affecting the direct I/O (DIO) to buffered write fallback path in ext4_dio_write_iter(). On no-extent inodes (e.g., ext3), DIO writes to holes cause a fallback to buffered I/O. An unprotected window exists between ext4_buff...

CVE-2026-92500

This CVE affects the Linux kernel ext4 filesystem . A race condition exists between write_begin and write_end handlers: a concurrent thread (such as ext4_page_mkwrite) can convert inline data to an extent during this window, causing the write_end handlers to fall through to extent-based logic wit...
