CVE-2025-68786

CVE-2025-68786 affects the Linux kernel ksmbd code path. When i_size equals the requested size (including 0), the prior check_lock_range call used size-1 and could underflow, which is mitigated by skipping the equal-size case. The issue is resolved in upstream kernel 6.6.120, and Mageia advisorie...

CVE-2025-68786 ksmbd: skip lock-range check on equal size to avoid size==0 underflow

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 checklockrangefilp, isize, size - 1, WRITE, which computes size - 1 and can underflow for...
