What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel by adding a null check before dereferencing the stream pointer in the amdgpu_dm driver. Users should apply the official Linux kernel updates that include this fix. Since this is not a cloud service, remediation requires updating the affected Linux kernel version once the patch is released.
Description
CVE-2024-49896 is a medium-severity vulnerability in the Linux kernel's AMD GPU display driver (amdgpu_dm). It involves a null pointer dereference issue where a null stream can be passed to the function dc_is_stream_unchanged without proper null checking, potentially causing a denial of service. The flaw was identified and fixed by adding a check for null streams before comparison.
