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...
