CVE-2024-56750 Information

Description

In the Linux kernel the following vulnerability has been resolved:

erofs: fix blksize < PAGE_SIZE for file-backed mounts

Adjust sb->s_blocksize_bits directly for file-backed mounts when the fs block size is smaller than PAGE_SIZE.

Previously EROFS used sb_set_blocksize() which caused a panic if bdev-backed mounts is not used.
