CVE-2025-38187 Information

Jul 05, 2025 cve

Description

In the Linux kernel the following vulnerability has been resolved:

drm/nouveau: fix a use-after-free in r535_gsp_rpc_push()

The RPC container is released after being passed to r535_gsp_rpc_send().

When sending the initial fragment of a large RPC and passing the caller’s RPC container the container will be freed prematurely. Subsequent attempts to send remaining fragments will therefore result in a use-after-free.

Allocate a temporary RPC container for holding the initial fragment of a large RPC when sending. Free the caller’s container when all fragments are successfully sent.

[ Rebase onto Blackwell changes. - Danilo ]
