Affected: Linux

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

s390/ctcm: Fix double-kfree

The function 'mpc_rcvd_sweep_req(mpcginfo)' is called conditionally from function 'ctcmpc_unpack_skb'. It frees passed mpcginfo. After that a call to function 'kfree' in function 'ctcmpc_unpack_skb' frees it again.

Remove 'kfree' call in function 'mpc_rcvd_sweep_req(mpcginfo)'.

Bug detected by the clang static analyzer.
