In the Linux kernel, the following vulnerability has been resolved: s390/ctcm: Fix double-kfree The function 'mpcrcvdsweepreq(mpcginfo)' is called conditionally from function 'ctcmpcunpackskb'. It frees passed mpcginfo. After that a call to function 'kfree' in function 'ctcmpcunpackskb' frees it again. Remove 'kfree' call in function 'mpcrcvdsweepreq(mpcginfo)'. Bug detected by the clang static analyzer.
