Linux Kernel Security Vulnerabilities

The Linux kernel version 4.7 contains a security vulnerability. This vulnerability stems from the insufficient estimation of the number of idle TX descriptors required for TSO traffic by the stmmactsoxmit function. As a result, writes that exceed the available descriptors may overwrite descriptor...
