CVE-2026-43346

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: ptp: don&amp;#39;t WARN when controlling PF is unavailable<br /> <br /> In VFIO passthrough setups, it is possible to pass through only a PF<br /> which doesn&amp;#39;t own the source timer. In that case the PTP controlling PF<br /> (adapter-&gt;ctrl_pf) is never initialized in the VM, so ice_get_ctrl_ptp()<br /> returns NULL and triggers WARN_ON() in ice_ptp_setup_pf().<br /> <br /> Since this is an expected behavior in that configuration, replace<br /> WARN_ON() with an informational message and return -EOPNOTSUPP.
