A patch is available and has been released by Ubuntu as part of their security updates. Users should update their Linux kernel packages to the fixed versions listed in the vendor advisories (e.g., versions 5.4.0-1142.152~18.04.1 and later). After updating, a system reboot is required to apply the fixes. No additional mitigation steps are necessary beyond applying the official patches.
Description
CVE-2024-49896 is a vulnerability in the Linux kernel's AMD GPU display driver where a null stream pointer could be passed to a function without proper null checking, leading to a potential null pointer dereference. This issue was identified and fixed by adding a check to ensure the stream is not null before comparison. The vulnerability affects certain versions of the Linux kernel used in Ubuntu distributions and has a medium severity rating with an impact on availability.
