ksmbd: fix reference count leak in smb_check_perm_dacl()
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix reference count leak in smb_check_perm_dacl() The issue happens in a specific path in smb_check_perm_dacl(). When "id" and "uid" have the same value, the function simply jumps out of the loop without decrementing the reference count of the object "posix_acls", which is increased by get_acl() earlier. This may result in memory leaks. Fix it by decreasing the reference count of "posix_acls" before jumping to label "check_access_bits".
