CVE-2026-43345 (GCVE-0-2026-43345)

Vulnerability from cvelistv5 – Published: 2026-05-08 13:39 – Updated: 2026-08-05 12:27

Title

net: ipa: fix event ring index not programmed for IPA v5.0+

Summary

In the Linux kernel, the following vulnerability has been resolved: net: ipa: fix event ring index not programmed for IPA v5.0+ For IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to CH_C_CNTXT_1. The v5.0 register definition intended to define this field in the CH_C_CNTXT_1 fmask array but used the old identifier of ERINDEX instead of CH_ERINDEX. Without a valid event ring, GSI channels could never signal transfer completions. This caused gsi_channel_trans_quiesce() to block forever in wait_for_completion(). At least for IPA v5.2 this resolves an issue seen where runtime suspend, system suspend, and remoteproc stop all hanged forever. It also meant the IPA data path was completely non functional.

No race, heap shaping, or attacker-uncontrolled timing is needed once the affected channel is programmed and used.\nPR:N - For the remote packet/data-path scenario, the attacker does not need local credentials or kernel capabilities. The relevant receive path is packet-driven after the device and modem interface are configured by the system.\nUI:N - No victim action is required beyond the affected device being online with its IPA modem data path configured. Traffic or normal power-management transitions can exercise the broken completion path.\nS:U - The impact remains within the same kernel/device security authority. This is not a VM escape, IOMMU bypass, or cross-sandbox boundary violation.\nC:N - The bug is an incorrect hardware register field mask that prevents completion signaling; I found no out-of-bounds access, use-after-free, or attacker-readable memory exposure. The event rings are driver-allocated DMA rings, not an arbitrary disclosure primitive.\nI:N - The observed and code-supported impact is loss of completion signaling and broken data-path operation, not attacker-controlled modification of kernel memory or persistent data. There is no evident arbitrary write or control-flow corruption primitive.\nA:H - Missing completions cause waits such as gsi_channel_trans_quiesce() to block forever, hanging runtime suspend, system suspend, and remoteproc stop. The IPA data path can also become completely nonfunctional, so availability impact is high."
