- Summary
- [none]
- Details
-
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 CAPNET_ADMIN privileges to crash the system.
