Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: algif_hash - Remove bogus SGL free on zero-length error path<br /> <br /> When a zero-length message is hashed by algif_hash, and an error<br /> is triggered, it tries to free an SG list that was never allocated<br /> in the first place. Fix this by not freeing the SG list on the<br /> zero-length error path.
