Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the Linux kernel, specifically with the erofs file system. It has been resolved by adjusting sb->s blocksize{, bits} directly for file-backed mounts when the file system block size is smaller than PAGE SIZE. Previously, EROFS used sb set blocksize(), which caused a panic if bdev-backed mounts were not used.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
