Detailsinfo

A vulnerability was found in Linux Kernel up to 6.11.10/6.12.1. It has been rated as critical. Affected by this issue is the function dcn20_program_pipe of the component AMD Display. The manipulation of the argument pipe_ctx with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix null check for pipe_ctx->plane_state in dcn20_program_pipe This commit addresses a null pointer dereference issue in dcn20_program_pipe(). Previously, commit 8e4ed3cf1642 ("drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe") partially fixed the null pointer dereference issue. However, in dcn20_update_dchubp_dpp(), the variable pipe_ctx is passed in, and plane_state is accessed again through pipe_ctx. Multiple if statements directly call attributes of plane_state, leading to potential null pointer dereference issues. This patch adds necessary null checks to ensure stability.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2024-53201 since 11/19/2024. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 216943 (Ubuntu 24.04 LTS : Linux kernel vulnerabilities (USN-7310-1)), which helps to determine the existence of the flaw in a target environment.
