CVE-2026-97958

The Linux kernel is vulnerable to a CPU hogging issue in net/sched: cls_api due to how tc_ctl_chain() handles repeated RTM_GETCHAIN requests. If a netlink socket sends these requests without consuming the responses, netlink_attachskb() may return -EAGAIN when the receive buffer is full, causing t...

CVE-2026-97616 net/sched: act_api: release all action references on NEWACTION failure

In the Linux kernel, the following vulnerability has been resolved: net/sched: actapi: release all action references on NEWACTION failure When a batched RTMNEWACTION request replaces an existing action, tcfidrcheckalloc takes a temporary reference on it. If a later action fails to initialize,...

CVE-2026-97616

The Linux kernel contains a memory leak vulnerability within the net/sched: act_api component. During a batched RTM_NEWACTION request, tcf_idr_check_alloc() takes a temporary reference on an action. If a subsequent action fails to initialize, tcf_action_destroy() uses strict release semantics tha...
