Vulnerability from github – Published: 2026-05-08 15:31 – Updated: 2026-05-15 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ice: ptp: don't WARN when controlling PF is unavailable

In VFIO passthrough setups, it is possible to pass through only a PF which doesn't own the source timer. In that case the PTP controlling PF (adapter->ctrl_pf) is never initialized in the VM, so ice_get_ctrl_ptp() returns NULL and triggers WARN_ON() in ice_ptp_setup_pf().

Since this is an expected behavior in that configuration, replace WARN_ON() with an informational message and return -EOPNOTSUPP.

Severity ?

5.5 (Medium)
