CVE-2024-53201

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:
27/12/2024
Last modified:

Description

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