CVE-2026-98382 bpf: Reject dev-bound-only programs on other devices

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject dev-bound-only programs on other devices bpfoffloaddevmatch falls back to comparing offdev pointers after an exact netdev mismatch. Bound-only programs normally have NULL offdevs, so unrelated netdevs compare equal. A...

CVE-2026-98382

The Linux kernel contains a vulnerability where bound-only BPF programs can incorrectly match sibling ports due to a fallback mechanism in __bpf_offload_dev_match(). Because these programs typically have NULL offdevs , unrelated netdevs can compare as equal on offload-registered netdevs. An attac...

CVE-2026-98381

The Linux kernel contains a vulnerability where the veth component fails to properly manage XDP program pointers during a channel resize. Specifically, the function veth_set_channels() tears down XDP resources for removed RX queues but fails to clear rq->xdp_prog. This allows queues to retain ...

CVE-2026-98380

A vulnerability exists in the Linux kernel 's net/sched component where tcf_idr_delete_index() fails to properly handle IDR error pointers . Specifically, if an unlocked classifier removes an action and reserves the same IDR slot with ERR_PTR(-EBUSY) between the lookup and deletion, the system tr...

CVE-2026-98379

The Linux kernel contains a vulnerability in the netfilter: ip6t_rpfilter component. The ip6_route_lookup() function can return a route where rt6i_idev is NULL if an external nexthop device's MTU is lowered below IPV6_MIN_MTU, causing the inet6_dev to be torn down while the route remains in the F...
