GHSA-mprr-p5pf-vhc3 
In the Linux kernel, the following vulnerability has been resolved:fs/ntfs3: Validate BOOT record_sizeWhen the NTFS BOOT record_size field < 0, it represents a
shift value. However, there is no sanity check on the shift result
and the sbi->record_bits calculation through blksize_bits() assumes
the size always > 256, which could lead to NPD while mounting a
malformed NTFS image.[  318.675159] BUG: kernel NULL pointer dereference, address: 0000000000000158
