Summary
CVE-2024-56750 is a vulnerability affecting the Linux kernel's EROFS file system. This issue involves the adjustment of block sizes for file-backed mounts. Previously, EROFS utilized the function sb_set_blocksize() which resulted in a panic when dealing with block sizes smaller than PAGE_SIZE in bdev-backed mounts. The resolution to this vulnerability is to adjust sb->s_blocksize{,_bits} directly for file-backed mounts, ensuring proper handling of smaller block sizes and avoiding potential panics.
