A vulnerability in the Linux kernel's ksmbd component allowed skipping mandatory byte-range lock checks for single-byte ranges. This flaw could permit operations such as one-byte reads, writes, copychunk operations, and one-byte truncates to proceed without verifying conflicting locks. The issue arises because check_lock_range() uses inclusive ranges, and a shortcut for start == end incorrectly bypasses lock checks for single-byte ranges. This vulnerability has been resolved by removing the shortcut and ensuring proper lock checks are enforced.
