CVSS: 7.7EPSS: 0%CPEs: 8EXPL: 0CVE-2022-48651 – ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header
https://notcve.org/view.php?id=CVE-2022-48651
In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header If an AF_PACKET socket is used to send packets through ipvlan and the default xmit function of the AF_PACKET socket is changed from dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and remains as the initial value of 65535, this may trigger slab-out-of-bounds bugs as following: ================================================================= UG: KASAN: slab-out-of-bounds in ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan] PU: 2 PID: 1768 Comm: raw_send Kdump: loaded Not tainted 6.0.0-rc4+ #6 ardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 all Trace: print_address_description.constprop.0+0x1d/0x160 print_report.cold+0x4f/0x112 kasan_report+0xa3/0x130 ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan] ipvlan_start_xmit+0x29/0xa0 [ipvlan] __dev_direct_xmit+0x2e2/0x380 packet_direct_xmit+0x22/0x60 packet_snd+0x7c9/0xc40 sock_sendmsg+0x9a/0xa0 __sys_sendto+0x18a/0x230 __x64_sys_sendto+0x74/0x90 do_syscall_64+0x3b/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd The root cause is: 1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW and skb->protocol is not specified as in packet_parse_headers() 2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit() In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which use "skb->head + skb->mac_header", out-of-bound access occurs. This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2() and reset mac header in multicast to solve this out-of-bound bug. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ipvlan: corrige errores fuera de los límites causados por skb->mac_header no configurado si se usa un socket AF_PACKET para enviar paquetes a través de ipvlan y se cambia la función xmit predeterminada del socket AF_PACKET desde dev_queue_xmit() a paquete_direct_xmit() a través de setsockopt() con el nombre de opción PACKET_QDISC_BYPASS, es posible que skb->mac_header no se restablezca y permanezca en el valor inicial de 65535, esto puede desencadenar errores de losa fuera de los límites como se muestra a continuación : =================================================== ================ UG: KASAN: losa fuera de los límites en ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan] PU: 2 PID: 1768 Comm: raw_send Kdump: cargado No contaminado 6.0.0-rc4+ #6 nombre de hardware: PC estándar QEMU (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 todo Seguimiento: print_address_description.constprop.0+0x1d/0x160 print_report.cold+0x4f/0x112 kasan_report+ 0xa3/0x130 ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan] ipvlan_start_xmit+0x29/0xa0 [ipvlan] __dev_direct_xmit+0x2e2/0x380 paquete_direct_xmit+0x22/0x60 paquete_snd+0x7c9/0xc40 0x9a/0xa0 __sys_sendto+0x18a/0x230 __x64_sys_sendto+0x74/0x90 do_syscall_64 +0x3b/0x90 Entry_SYSCALL_64_after_hwframe+0x63/0xcd La causa principal es: 1. paquete_snd() solo restablece skb->mac_header cuando sock->tipo es SOCK_RAW y skb->protocolo no se especifica como en paquete_parse_headers() 2. paquete_direct_xmit() no restablece skb->mac_header como dev_queue_xmit() En este caso, skb->mac_header es 65535 cuando se llama a ipvlan_xmit_mode_l2(). Entonces, cuando ipvlan_xmit_mode_l2() obtiene el encabezado mac con eth_hdr() que usa "skb->head + skb->mac_header", se produce un acceso fuera de los límites. Este parche reemplaza eth_hdr() con skb_eth_hdr() en ipvlan_xmit_mode_l2() y restablece el encabezado de mac en multidifusión para resolver este error fuera de los límites. • https://git.kernel.org/stable/c/2ad7bf3638411cb547f2823df08166c13ab04269 https://git.kernel.org/stable/c/e2b46cd5796f083e452fbc624f65b80328b0c1a4 https://git.kernel.org/stable/c/25efdbe5fe542c3063d1948cc4e98abcb57621ca https://git.kernel.org/stable/c/bffcdade259c05ab3436b5fab711612093c275ef https://git.kernel.org/stable/c/346e94aa4a99378592c46d6a34c72703a32bd5be https://git.kernel.org/stable/c/ab4a733874ead120691e8038272d22f8444d3638 https://git.kernel.org/stable/c/8d06006c7eb75587d986da46c48ba9274f94e8e7 https://git.kernel.org/stable/c/b583e6b25bf9321c91154f6c78d2173ef • CWE-125: Out-of-bounds Read •
