  "description": "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 \u0022id\u0022 and \u0022uid\u0022 have the same value, the function simply jumps out of the loop without decrementing the reference count of the object \u0022posix_acls\u0022, which is increased by get_acl() earlier. This may result in memory leaks.  Fix it by decreasing the reference count of \u0022posix_acls\u0022 before jumping to label \u0022check_access_bits\u0022.",
