CVE-2026-43081: net: ipa: fix GENERIC_CMD register field masks for IPA v5.0+

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2aa50d2c1f631b405849da246043c6f683af7489, 9709b56d908acc120fe8b4ae250b3c9d749ea832, a7d326dfb13b5a0763eccfd78836fe15199fc499.

Low priority for now. Upgrade to Linux Linux 2aa50d2c1f631b405849da246043c6f683af7489, 9709b56d908acc120fe8b4ae250b3c9d749ea832, a7d326dfb13b5a0763eccfd78836fe15199fc499 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
