CVE-2023-42754

Published: 5 October 2023

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 __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system.

From the Ubuntu Security Team

Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket buffers (skb) when performing IP routing in certain circumstances, leading to a null pointer dereference vulnerability. A privileged attacker could use this to cause a denial of service (system crash).

Notes

AuthorNote
rodrigo-zaiden
first publication of USN-6536-1 wrongly announced that
linux-azure on mantic fixed this issue in version 6.5.0-1009.9. It was
fixed with USN-6573-1.

Mitigation

If not needed, disable the ability for unprivileged users
to create namespaces. To do this temporarily, do:
  sudo sysctl -w kernel.unprivileged_userns_clone=0
To disable across reboots, do:
  echo kernel.unprivileged_userns_clone=0 | \
  sudo tee /etc/sysctl.d/99-disable-unpriv-userns.conf
