CVE-2022-49919

CVE-2022-49919 : In the Linux kernel, the nf_tables flow rule object release path was fixed. The underlying issue was a use-after-free (UAF) triggered by races with the netlink notifier, observed when the flow rule object is accessed only from the control plane (no data packets traverse it). The ...
