CVE-2026-43081

Summary

In the Linux kernel, the following vulnerability has been resolved:

net: ipa: fix GENERIC_CMD register field masks for IPA v5.0+

Fix the field masks to match the hardware layout documented in downstream GSI (GSI_V3_0_EE_n_GSI_EE_GENERIC_CMD_*).

Notably this fixes a WARN I was seeing when I tried to send "stop" to the MPSS remoteproc while IPA was up.
