CVE-2025-68786

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ksmbd: skip lock-range check on equal size to avoid size==0 underflow<br /> <br /> When size equals the current i_size (including 0), the code used to call<br /> check_lock_range(filp, i_size, size - 1, WRITE), which computes `size - 1`<br /> and can underflow for size==0. Skip the equal case.
