UBUNTU-CVE-2023-42754

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...

kernel: ipvlan: out-of-bounds write caused by unclear skb->cb

A flaw was found in the IPVLAN network driver in the Linux kernel. This issue is caused by missing skb-cb initialization in ipoptionsecho and can lead to an out-of-bounds write stack overflow.
