In the Linux kernel, the following vulnerability has been resolved:
ice: Fix memory corruption in VF driver
Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,
while VF still has queues configured, VF may unmap DMA resources.
In such scenario device still can map packets to memory, which ends up
silently corrupting it.
Previously, VF driver could experience memory corruption, which lead to
crash:

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.
