Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Linux kernel's net/sched act_ife action, from version 4.11 onward, mishandles frames that lack an Ethernet header, such as packets redirected from a PPP device, and this can crash the kernel. The source gives few details on what access an attacker needs. Upgrade to 6.1.191, 6.6.160, 6.12.114, 6.18.52, or a later release in those series.
