CVE-2026-43346

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description In VFIO passthrough setups, it is possible to pass through only a Physical Function (PF) that does not own the source timer. In such configurations, the PTP controlling PF (adapter->ctrl pf) is not initialized in the Virtual Machine (VM), causing the ice get ctrl ptp() function to return NULL. This triggers a WARN ON() call within the ice ptp setup pf() function. This behavior is expected in these specific configurations.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
