CVE-2022-49920

Affected product: Linux kernel (netfilter nf_tables). Vulnerability arises from a race in the netlink notifier during object release after the RCU grace period, where the netlink notifier handler might win a race to remove objects still referenced by the transaction context. Root cause: commit re...

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 ...
