Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the tunxdpone function, when buildskb fails, the function sets ret to -ENOMEM and jumps to the out label. This causes the function to return without freeing the page that was allocated by vhostnetbuildxdp for the frame. Simila...
