CVE-2024-42257 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ext4: use memtostr_pad() for s_volume_name

As with the other strings in struct ext4_super_block s_volume_name is not NUL terminated. The other strings were marked in commit 072ebb3bffe6 (xt4: add nonstring annotations to ext4.h). Using strscpy() isn’t the right replacement for strncpy(); it should use memtostr_pad() instead.
