CVE-2026-98474: s390/pci: Fix missing device lock in zpci_report_status()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 0261aef4b15efcee2860ab857e5cb05e9bfa47b0, 1b957d5c2f737cda731cb1a1b71a7524d54538f2, 743a8458978d13d84a1cf74bcd29b9959a75d3a0.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0261aef4b15efcee2860ab857e5cb05e9bfa47b0, 1b957d5c2f737cda731cb1a1b71a7524d54538f2, 743a8458978d13d84a1cf74bcd29b9959a75d3a0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: s390/pci: Fix missing device lock in zpci_report_status() When pdev is non-NULL, zpci_report_status() accesses the device's driver. To get a consistent state matching the recovery, the device lock needs to be held. Do so by expanding the existing device lock critical section. The lock only needs to be held when the pdev is non-NULL, so extract the pdev-specific reporting into a helper function which also adds a lockdep assertion to detect calls without the device lock held.
