CVE-2022-49153

CVE-2022-49153 affects the Linux kernel via the wireguard path: when sending to a peer, skb memory is not freed if IPv6 is disabled, causing a memory leak. The root cause is missing kfree_skb() in the send6() handling within wg_socket_send_buffer_to_peer/..send_buffer_to_peer() and related code p...

CVE-2022-49084

CVE-2022-49084 is addressed in the Linux kernel component related to qede: a null pointer dereference can occur when build_skb() fails under memory pressure in qede_build_skb(); the fix adds a check for NULL and ensures callers handle NULL returns to prevent kernel panics. Connected advisories (E...

CVE-2022-49066 veth: Ensure eth header is in skb's linear part

In the Linux kernel, the following vulnerability has been resolved: veth: Ensure eth header is in skb's linear part After feeding a decapsulated packet to a veth device with actmirred, skbheadlen may be 0. But vethxmit calls devforwardskb, which expects at least ETHHLEN byte of linear data as...

CVE-2022-49066

The CVE-2022-49066 issue affects the Linux kernel’s veth path. When a decapsulated packet is fed to a veth device with act_mirred, skb_headlen() may be 0, yet veth_xmit() forwards the skb to __dev_forward_skb() which unconditionally requires ETH_HLEN bytes of linear data. The root cause is the mi...
