UBUNTU-CVE-2024-53057: High severity ubuntu/linux vulnerability

Q: What access and conditions are needed to exploit this issue?

The attack vector is local and requires low privileges, with no user interaction. Exploitation has high attack complexity and depends on a traffic-control qdisc hierarchy containing an egress qdisc with major handle ffff:, including qdiscs such as DRR that maintain an active class list.

Q: What is the potential impact if exploitation succeeds?

The flaw can cause a use-after-free through a dangling class pointer. The provided severity vector rates confidentiality, integrity, and availability impact as high.

Q: Which Ubuntu kernel package families are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-aws, ubuntu/linux-aws-fips, ubuntu/linux-azure, ubuntu/linux-azure-fips, ubuntu/linux-gcp, and ubuntu/linux-gcp-fips.

Updated

In the Linux kernel, the following vulnerability has been resolved: net/sched: stop qdisctreereducebacklog on TCHROOT In qdisctreereducebacklog, Qdiscs with major handle ffff: are assumed to be either root or ingress. This assumption is bogus since it's valid to create egress qdiscs with major handle ffff: Budimir Markovic found that for qdiscs like DRR that maintain an active class list, it will cause a UAF with a dangling class pointer. In 066a3b5b2346, the concern was to avoid iterating over the ingress qdisc since its parent is itself. The proper fix is to stop when parent TCHROOT is reached because the only way to retrieve ingress is when a hierarchy which does not contain a ffff: major handle call into qdisclookup with TCHMAJ(TCHROOT). In the scenario where major ffff: is an egress qdisc in any of the tree levels, the updates will also propagate to TCHROOT, which then the iteration must stop. net/sched/schapi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

Frequently Asked Questions

What access and conditions are needed to exploit this issue?

The attack vector is local and requires low privileges, with no user interaction. Exploitation has high attack complexity and depends on a traffic-control qdisc hierarchy containing an egress qdisc with major handle ffff:, including qdiscs such as DRR that maintain an active class list.

What is the potential impact if exploitation succeeds?

The flaw can cause a use-after-free through a dangling class pointer. The provided severity vector rates confidentiality, integrity, and availability impact as high.

Which Ubuntu kernel package families are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-aws, ubuntu/linux-aws-fips, ubuntu/linux-azure, ubuntu/linux-azure-fips, ubuntu/linux-gcp, and ubuntu/linux-gcp-fips.
