CVE-2024-42257

The CVE-2024-42257 issue affects the Linux kernel ext4 code: the s_volume_name field in ext4_super_block was not NUL terminated. The root cause was using the wrong string copy approach; memtostr_pad() should be used instead of strncpy(), aligning with prior nonstring annotations in ext4.h. The re...
