CVE-2026-64531 OVSwrap Linux Kernel Root Exploit
🟠High | Source: The Hacker News A memory corruption vulnerability (CVE-2026-64531) in the Linux kernel’s Open vSwitch datapath allows an unprivileged local user to escalate privileges to root. The flaw affects a wide range of default-configured Linux distributions, and a public exploit is already available with pre-built payloads targeting around 800 kernel versions. This makes exploitation straightforward even for less sophisticated attackers. Security Architect’s Take: Prioritise patching affected Linux kernel versions across all compute workloads, particularly cloud VMs and container hosts running Open vSwitch — apply vendor-supplied kernel updates immediately or, where patching is not immediately possible, restrict local user access and consider disabling or unloading the openvswitch kernel module if it is not required. ...
