CVE-2026-68121

In the Linux kernel, the following vulnerability has been resolved: pppoe: reload header pointer after devhardheader pppoesendmsg saves a pointer to the PPPoE header before calling devhardheader. Device header callbacks are allowed to reallocate the skb head, invalidating pointers into it. This c...
