A patch is available and should be applied by updating to Linux kernel versions 5.15.0-1088.95~20.04.1 or later as listed in the fixed versions. The Ubuntu security advisory USN-7594-1 provides official updates addressing this and other kernel vulnerabilities. Users should apply these official kernel updates promptly to remediate the issue.
Description
A division by zero vulnerability was identified and fixed in the AMD GPU power management code (drm/amd/pm) of the Linux kernel. The flaw occurs when a user sets a speed value greater than UINT_MAX/8, leading to a division by zero error. This issue affects multiple Linux kernel versions prior to fixed releases in the 5.15 series and some specific older versions. The vulnerability has a medium severity rating with a CVSS score of 5.5 and impacts system availability by causing a denial of service. The issue has been addressed in official Linux kernel updates.
