In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: E-Switch, pair only capable devices
OFFLOADS paring using devcom is possible only on devices
that support LAG. Filter based on lag capabilities.
This fixes an issue where mlx5_get_next_phys_dev() was
called without holding the interface lock.
This issue was found when commit
bc4c2f2e0179 ("net/mlx5: Lag, filter non compatible devices")
added an assert that verifies the interface lock is held.

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.
