Details

In the Linux kernel, the following vulnerability has been resolved:

bpf, sockmap: Fix potential memory leak on unlikely error case

If skb_linearize is needed and fails we could leak a msg on the error handling. To fix ensure we kfree the msg block before returning error. Found during code review.
