Linux Kernel ksmbd Component Lock Handling Vulnerability

A vulnerability in the Linux kernel's ksmbd component has been addressed. The issue arose in the SMB2 lock handling, where the lock count could incorrectly reflect an old value if it was greater than one. This misalignment could trigger a bug-on trap during error handling, as the flags were not properly synchronized with the smb_lock status.

Impact

The vulnerability could lead to improper lock management, causing error handling routines to malfunction by freeing locks that were not correctly accounted for.
