kernel: ipvs: clear IPv4 options after rebasing tunnel ICMP errors

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When processing Internet Control Message Protocol ICMP errors for tunneled packets, the system can incorrectly use a stale IPv4 option offset. A remote attacker could exploit this by sending a specially crafted ICMP packet,...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises from IPVS’s handling of ICMP errors from tunnels. When using pskbpull, IPVS strips off the external header. However, it does not ensure that the internal IP header is located within the skb headroom, and it does not properly...
