Astra Linux – Vulnerability in Qemu

An integer overflow issue was identified in the vmxnet3 NIC emulator of QEMU for versions up to v5.2.0. This issue can occur if a guest provides invalid values for the rx/tx queue size or other NIC parameters. A privileged guest user may exploit this flaw to crash the QEMU process on the host,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: sfc: fixed the issue where all channels had TX queues. Normally, all channels have both RX and TX queues. However, this is not true when modparam efxseparatetxchannels=1 is used. In such cases, some channels only have RX queue...
