CVE-2024-50162

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

bpf: devmap: provide rxq after redirect

rxq contains a pointer to the device from where the redirect happened. Currently, the BPF program that was executed after a redirect via BPF_MAP_TYPE_DEVMAP* does not have it set.

This is particularly bad since accessing ingress_ifindex, e.g.

depends on access to rxq, so a NULL pointer gets dereferenced:

        return XDP_PASS;
}
