CVE-2026-23458

The CVE-2026-23458 entry describes a Linux kernel netfilter use-after-free in ctnetlink_dump_exp_ct(). The code stores a conntrack pointer in cb->data for the netlink dump callback (ctnetlink_exp_ct_dump_table()) and drops the conntrack reference after netlink_dump_start(), so multi-round dump...

CVE-2026-23436

The CVE-2026-23436 issue affects the Linux kernel's net: shaper component. A race could occur when a netdev is unregistered between taking a reference during Netlink prep and locking/RCU in the callback, potentially leaking the hierarchy after a flush. The fix applies the instance lock in pre- st...
