CVE-2026-10645 Out-of-bounds read in Zephyr ext2 directory entry traversal from a crafted filesystem image

The Zephyr ext2 filesystem driver subsys/fs/ext2 trusted the on-disk directory entry fields dereclen and denamelen when walking a directory block. ext2fetchdirentry guarded only with denamelen EXT2MAXFILENAME, but denamelen is a uint8t and EXT2MAXFILENAME is 255, so the check is always false; the...
