CVE-2026-90176

A flaw was found in ksmbd, a server message block SMB protocol implementation within the Linux kernel. A logic error in the checklockrange function, which is responsible for enforcing file locks, causes it to bypass mandatory byte-range lock checks for single-byte operations. This allows an...

SUSE CVE-2026-90176

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Do not skip lock checks for single-byte ranges checklockrange uses inclusive ranges. Its callers pass the end offset as start + length - 1, so start == end represents a valid single-byte range rather than an empty range. T...

CVE-2026-90176

This vulnerability affects the Linux kernel's ksmbd (in-kernel SMB/CIFS server) component. The function check_lock_range() uses inclusive ranges , so start == end represents a valid single-byte range. However, a shortcut incorrectly treats this case as an empty range, skipping mandatory byte-rang...
