Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/nouveau: fix a use-after-free in r535_gsp_rpc_push()<br /> <br /> The RPC container is released after being passed to r535_gsp_rpc_send().<br /> <br /> When sending the initial fragment of a large RPC and passing the<br /> caller&amp;#39;s RPC container, the container will be freed prematurely. Subsequent<br /> attempts to send remaining fragments will therefore result in a<br /> use-after-free.<br /> <br /> Allocate a temporary RPC container for holding the initial fragment of a<br /> large RPC when sending. Free the caller&amp;#39;s container when all fragments<br /> are successfully sent.<br /> <br /> [ Rebase onto Blackwell changes. - Danilo ]
