In the Linux kernel, the following vulnerability has been resolved:
net: netdevsim: don't try to destroy PHC on VFs
PHC gets initialized in nsim_init_netdevsim(), which
is only called if (nsim_dev_port_is_pf()).
Create a counterpart of nsim_init_netdevsim() and
move the mock_phc_destroy() there.
This fixes a crash trying to destroy netdevsim with
VFs instantiated, as caught by running the devlink.sh test:

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
