CVE-2023-53450

In the Linux kernel, the following vulnerability has been resolved:

ext4: remove a BUG_ON in ext4_mb_release_group_pa()

If a malicious fuzzer overwrites the ext4 superblock while it is
mounted such that the s_first_data_block is set to a very large
number, the calculation of the block group can underflow, and trigger
a BUG_ON check. Change this to be an ext4_warning so that we don't
crash the kernel.
