In the Linux kernel, the following vulnerability has been resolved: net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT In qdisc_tree_reduce_backlog, 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 TC_H_ROOT is reached because the only way to retrieve ingress is when a hierarchy which does not contain a ffff: major handle call into qdisc_lookup with TC_H_MAJ(TC_H_ROOT). In the scenario where major ffff: is an egress qdisc in any of the tree levels, the updates will also propagate to TC_H_ROOT, which then the iteration must stop. net/sched/sch_api.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7179-1 advisory.

    Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-     confusion error. A physically proximate remote attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2020-12351)

    Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly     initialize memory in some situations. A physically proximate remote attacker could use this to expose     sensitive information (kernel memory). (CVE-2020-12352)

    Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly     handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically     proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2020-24490)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (bookworm), these problems have been fixed in     version 6.1.119-1.

    We recommend that you upgrade your linux packages.
