CVE-2024-26951

CVE-2024-26951 (Linux kernel, WireGuard) : The bug occurs in the netlink dump when peers are removed with wg_peer_remove_all(): a cursored peer that has been removed can lead to iterating freed peers, causing a use-after-free. The fix changes the check from an empty peer_list to the dedicated is_...
