  "description": "In the Linux kernel, the following vulnerability has been resolved:  rxrpc, afs: Fix missing error pointer check after rxrpc_kernel_lookup_peer()  rxrpc_kernel_lookup_peer() can also return error pointers in addition to NULL, so just checking for NULL is not sufficient.  Fix this by:   (1) Changing rxrpc_kernel_lookup_peer() to return -ENOMEM rather than NULL      on allocation failure.   (2) Making the callers in afs use IS_ERR() and PTR_ERR() to pass on the      error code returned.",
