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