Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: Fixed the truesize for the mb-xdp-pass case. When mb-xdp is set and return is XDPPASS, the packet is converted from xdpbuff to skbuff using xdpupdateskbsharedinfo in bnxtxdpbuildskb. However, bnxtxdpbuildskb passes an...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: vmxnet3: Fixed malformed packet sizes in vmxnet3processxdp. The XDP handling of the vmxnet3 driver is buggy for packet sizes using ring0 i.e., packet sizes between 128 and 3k bytes. We noticed connectivity issues related to MT...
