The vulnerability of the handle_rx() function in the Linux operating system’s kernel allows a hacker to trigger a memory corruption in the kernel.

The vulnerability of the handlerx function in the vhostnet driver of the Linux operating system is related to writing data beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause damage to the kernel’s memory...
