CVE-2025-68334

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw related to platform/x86/amd/pmc support for the Van Gogh SoC. Specifically, the ROG Xbox Ally (non-X) SoC, which shares a similar architecture with the Steam Deck, lacks proper suspend handler support. This causes the device to fail to suspend and results in a crash of the AMD GPU driver during resume due to a power hang. The Steam Deck supports S3, but this support was removed in the Xbox Ally, which only uses S0ix suspend. The missing handler prevents the device from entering a suspended state, leading to the driver crash upon resuming.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
