CVE-2025-40198

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ext4: avoid potential buffer over-read in parse_apply_sb_mount_options()<br /> <br /> Unlike other strings in the ext4 superblock, we rely on tune2fs to<br /> make sure s_mount_opts is NUL terminated. Harden<br /> parse_apply_sb_mount_options() by treating s_mount_opts as a potential<br /> __nonstring.
