CVE-2026-74748

CVE-2026-74748 is a refcount race in the Linux kernel's netfilter ipset subsystem. The function __ip_set_put_byindex() resolves a set index under RCU but decrements the reference count only after acquiring ip_set_ref_lock. A concurrent ip_set_swap() call can interleave between these two steps, ca...

CVE-2026-74736

CVE-2026-74736 is a Linux kernel vulnerability in the net/sched cls_bpf classifier. The function cls_bpf_prog_from_efd() retrieved a SCHED_CLS program via bpf_prog_get_type_dev() without verifying that a device-bound (offloaded) BPF program's bound netdev matched the target TC netdev. This allowe...

kernel: netfilter: ipset: fix race between dump and ip_set_list resize

A flaw was found in the Linux kernel's netfilter ipset component. A race condition exists between the ipsetlist resize operation and dump operations. This can lead to a use-after-free vulnerability, where memory is accessed after it has been deallocated. A successful exploitation of this flaw cou...
