ipvs: ensure inner headers in ICMP errors are in headroom
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: ipvs: ensure inner headers in ICMP errors are in headroom Sashiko points out that after stripping the outer headers with pskb_pull() we should ensure the inner IP headers in ICMP errors from tunnels are present in the skb headroom for functions like ipv4_update_pmtu(), icmp_send() and IP_VS_DBG(). Also, add more checks for the length of the inner headers.

|---|---|---|---|---|---|---|
| CVSS 3.1 | CRITICAL | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 |
Solution
Ensure inner headers in ICMP errors are in headroom and add checks for inner header length.
- Update the Linux kernel to include the fix for ipvs.
- Ensure inner headers in ICMP errors are in headroom.
- Add checks for the length of inner headers.
