CVE-2022-49553
High 7.8
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
