- Details
-
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix small mempool leak in SMB2_negotiate()
In some cases of failure (dialect mismatches) in SMB2_negotiate(), after the request is sent, the checks would return -EIO when they should be rather setting rc = -EIO and jumping to neg_exit to free the response buffer from mempool.
