Description OSIDB Bzimport 2025-12-22 17:01:34 UTC 
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.
