Detail

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

fs/ntfs3: validate BOOT sectors_per_clusters

When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a shift value. Make sure that the shift value is not too large before using it (NTFS max cluster size is 2MB). Return -EVINVAL if it too large.

This prevents negative shift values and shift values that are larger than the field size.

Prevents this UBSAN error:

UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16
shift exponent -192 is negative
