CVE-2024-42257

Summary

CVE-2024-42257 is a newly identified vulnerability in the Linux kernel. This issue affects the ext4 file system's super block, specifically the s_volume_name variable. The problem stems from the fact that s_volume_name is not null-terminated, and the previous use of strscpy() was not the optimal solution. Instead, memtostr_pad() should have been employed to ensure proper string handling and avoid potential security risks.
