CVE-2026-81015

A flaw was found in the Linux kernel's AMD PMC Power Management Controller driver. When the amdstbs2dinit function fails during the driver's initialization process, it can lead to unreleased resources, specifically the LPS0 s2idle handler and debugfs directory. This resource leak can corrupt...

CVE-2026-81016

A flaw was found in the Linux kernel. Specifically, within the AMD Platform Management Controller PMC component, the amdstbs2dinit function does not properly validate memory addresses returned by System Management Unit SMU commands. This can result in the kernel attempting to map a critical memor...
