Linux Kernel 6.12-6.12.1 - Denial of Service via EROFS Block Size Handling

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.
