Follow-up on four Linux kernel local root flaws (DirtyAH6, PPPoEject, TUNderflow, DiagSpill), noting PPPoE is ubiquitous on ISP gateways.

An oss-security follow-up discusses four Linux local root vulnerabilities dubbed DirtyAH6, PPPoEject, TUNderflow, and DiagSpill. The commenter observes that PPPoE is widely deployed but mainly for ISP gateway communication rather than on end-user machines, which limits practical exposure. No CVE identifiers, patches, or exploitation evidence appear in the post.

Key facts
  • Four Linux kernel flaws reportedly allow local root privilege escalation
  • PPPoE deployment is concentrated on ISP gateways, not end-user hosts
  • No CVE ids, patch details, or exploitation evidence cited in the follow-up
