Description

af_packet: fix vlan_get_tci() vs MSG_PEEK

In the Linux kernel, the following vulnerability has been resolved:

af_packet: fix vlan_get_tci() vs MSG_PEEK

Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found

by syzbot.

Rework vlan_get_tci() to not touch skb at all,

so that it can be used from many cpus on the same skb.

Add a const qualifier to skb argument.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity low, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: High — total loss, or loss the attacker controls.
