In the Linux kernel, the following vulnerability has been resolved: net/sched: accept TCA_STAB only for root qdisc Most qdiscs maintain their backlog using qdisc_pkt_len(skb) on the assumption it is invariant between the enqueue() and dequeue() handlers. Unfortunately syzbot can crash a host rather easily using a TBF + SFQ combination, with an STAB on SFQ [1] We can't support TCA_STAB on arbitrary level, this would require to maintain per-qdisc storage.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7194-1 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)

    It was discovered that the CIFS network file system implementation in the Linux kernel did not properly     validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this     to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-6610)

    Supraja Sridhara, Benedict Schlter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the     Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit     emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service     (guest crash) or possibly execute arbitrary code. (CVE-2024-25744)

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-7186-2 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)

    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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-50039 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: accept TCA_STAB only for     root qdisc Most qdiscs maintain their backlog using qdisc_pkt_len(skb) on the assumption it is invariant     between the enqueue() and dequeue() handlers. Unfortunately syzbot can crash a host rather easily using a     TBF + SFQ combination, with an STAB on SFQ [1] We can't support TCA_STAB on arbitrary level, this would     require to maintain per-qdisc storage.
