CVE-2026-13478 Out-of-bounds read in Zephyr ext2 block-bitmap validation from a crafted s_blocks_count

The Zephyr ext2 filesystem driver validates the on-disk block bitmap in ext2initfs subsys/fs/ext2/ext2impl.c by passing fsblocks = sblockscount - sfirstdatablock to ext2bitmapcountset. That helper subsys/fs/ext2/ext2bitmap.c treats its argument as a number of bits and reads one bitmap byte per...

CVE-2026-13215 Zephyr ext2 mount: unvalidated superblock block size causes out-of-bounds write from a crafted filesystem image

The Zephyr ext2 filesystem driver fails to validate the slogblocksize field of the on-disk superblock when mounting a filesystem. ext2verifydisksuperblock in subsys/fs/ext2/ext2impl.c checks the magic number, revision, inode size and group counts, but never bounds slogblocksize. On a successful...

CVE-2026-74362

A flaw was found in the Linux kernel's ext2 filesystem. When performing write operations on files opened with OSYNC or ODSYNC flags, the system call write2 could incorrectly report success to a local user even if the data synchronization to disk failed. This could lead to data integrity issues, a...

CVE-2026-46002

Summary (CVE-2026-46002) The Linux kernel ext2 inode handling is fixed to catch a corner case where an inode with i_nlink == 0 and a non-zero i_mode could slip through if i_dtime is 0, allowing a crafted image to trigger WARN_ON in drop_nlink() via ext2_unlink/rename/rmdir. The patch extends the ...
