Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ionic: Use devconsumeskbany outside of NAPI. If we are not in a NAPI softirq context, we need to be careful about how we call napiconsumeskb. Specifically, we need to call it with budget == 0 to signal that we are not in a safe...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: virtio-net: Fixed pages leaking when building skb in big mode. We attempt to use buildskb if there is sufficient “tailroom”. However, we forget to release the unused pages that are chained via private in big mode, which can lead ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mlx5: fixed the potential use-of-free situation during the use of PTP queue FIFO. FIFO indexes are not checked during pop operations, which can lead to a use-of-free issue when popping items from an empty queue. This issue was...
