- Summary
- ksmbd: skip lock-range check on equal size to avoid size==0 underflow
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: skip lock-range check on equal size to avoid size==0 underflow
When size equals the current isize (including 0), the code used to call checklockrange(filp, isize, size - 1, WRITE), which computes
size - 1and can underflow for size==0. Skip the equal case. - Database specific
