CVE-2026-89490

CVE-2026-89490 affects the ocfs2 filesystem in the Linux kernel on 32-bit systems. In ocfs2_dir_foreach_blk_el(), the directory position mask derived from sb->s_blocksize (a 32-bit unsigned long) is zero-extended to 64 bits when ANDed with the loff_t-typed ctx->pos, silently clearing the hi...
