Linux Kernel parisc: Avoid Crash when Reprogramming ASP Chip Affinity
CVE-2025-71121 Published on January 14, 2026
parisc: Do not reprogram affinitiy on ASP chip
In the Linux kernel, the following vulnerability has been resolved:
parisc: Do not reprogram affinitiy on ASP chip
The ASP chip is a very old variant of the GSP chip and is used e.g. in
HP 730 workstations. When trying to reprogram the affinity it will crash
with a HPMC as the relevant registers don't seem to be at the usual
location. Let's avoid the crash by checking the sversion. Also note,
that reprogramming isn't necessary either, as the HP730 is a just a
single-CPU machine.
