Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
