CVE-2026-13478
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-2026-13478
CVE-2026-13478 is an out-of-bounds read in the Zephyr RTOS ext2 filesystem driver. During mount, ext2_init_fs() passes the superblock's s_blocks_count (unbounded) to ext2_bitmap_count_set(), which then reads up to ~512 MB past the single block-size bitmap buffer when a crafted image specifies an ...
