Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fs/ntfs3: validate BOOT sectors_per_clusters<br /> <br /> When the NTFS BOOT sectors_per_clusters field is &gt; 0x80, it represents a<br /> shift value. Make sure that the shift value is not too large before using<br /> it (NTFS max cluster size is 2MB). Return -EVINVAL if it too large.<br /> <br /> This prevents negative shift values and shift values that are larger than<br /> the field size.<br /> <br /> Prevents this UBSAN error:<br /> <br /> UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16<br /> shift exponent -192 is negative
