Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd/pmc: Add support for Van Gogh SoC The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver to crash while trying to resume afterwards due to a power hang. A flaw was found in the Linux kernel’s power management module for AMD Van Gogh System-on-Chip (SoC) devices. A local user could exploit this by attempting to suspend the system. Due to a missing handler for the S0ix suspend state, the device fails to suspend, causing the AMD GPU driver to crash during resume. This leads to a Denial of Service (DoS) on the affected system.Details
