CVE-2022-49084
In the Linux kernel, the following vulnerability has been resolved: qede: confirm skb is allocated before using qedebuildskb assumes buildskb always works and goes straight to skbreserve. However, buildskb can fail under memory pressure. This results in a kernel panic because the skb to reserve i...
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...
