The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5951-1 advisory.

    It was discovered that the Upper Level Protocol (ULP) subsystem in the Linux kernel did not properly     handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability.
    A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2023-0461)

    It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some     situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3169)

    It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A     local attacker could possibly use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2022-3424)

    Gwangun Jung discovered a race condition in the IPv4 implementation in the Linux kernel when deleting     multipath routes, resulting in an out-of-bounds read. An attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3435)

    It was discovered that a race condition existed in the Kernel Connection Multiplexor (KCM) socket     implementation in the Linux kernel when releasing sockets in certain situations. A local attacker could     use this to cause a denial of service (system crash). (CVE-2022-3521)

    It was discovered that the Netronome Ethernet driver in the Linux kernel contained a use-after-free     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2022-3545)

    It was discovered that the hugetlb implementation in the Linux kernel contained a race condition in some     situations. A local attacker could use this to cause a denial of service (system crash) or expose     sensitive information (kernel memory). (CVE-2022-3623)

    Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an out-of-     bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-36280)

    Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not properly perform reference     counting in some situations, leading to a use- after-free vulnerability. A local attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41218)

    It was discovered that the Intel i915 graphics driver in the Linux kernel did not perform a GPU TLB flush     in some situations. A local attacker could use this to cause a denial of service or possibly execute     arbitrary code. (CVE-2022-4139)

    It was discovered that a race condition existed in the Xen network backend driver in the Linux kernel when     handling dropped packets in certain circumstances. An attacker could use this to cause a denial of service     (kernel deadlock). (CVE-2022-42328, CVE-2022-42329)

    It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate offsets,     leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service     (system crash). (CVE-2022-47520)

    It was discovered that the network queuing discipline implementation in the Linux kernel contained a null     pointer dereference in some situations. A local attacker could use this to cause a denial of service     (system crash). (CVE-2022-47929)

    Jos Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did     not properly protect against indirect branch prediction attacks in some situations. A local attacker could     possibly use this to expose sensitive information. (CVE-2023-0045)

    It was discovered that a use-after-free vulnerability existed in the Advanced Linux Sound Architecture     (ALSA) subsystem. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-0266)

    Kyle Zeng discovered that the IPv6 implementation in the Linux kernel contained a NULL pointer dereference     vulnerability in certain situations. A local attacker could use this to cause a denial of service (system     crash). (CVE-2023-0394)

    It was discovered that the Android Binder IPC subsystem in the Linux kernel did not properly validate     inputs in some situations, leading to a use- after-free vulnerability. A local attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-20938)

    Kyle Zeng discovered that the class-based queuing discipline implementation in the Linux kernel contained     a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service     (system crash). (CVE-2023-23454)

    Kyle Zeng discovered that the ATM VC queuing discipline implementation in the Linux kernel contained a     type confusion vulnerability in some situations. An attacker could use this to cause a denial of service     (system crash). (CVE-2023-23455)

Tenable has extracted the preceding description block directly from the Ubuntu 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 NewStart CGSL host, running version MAIN 6.06, has kernel packages installed that are affected by multiple vulnerabilities:

  - In binder_transaction_buffer_release of binder.c, there is a possible use after free due to improper input     validation. This could lead to local escalation of privilege with no additional execution privileges     needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid     ID: A-257685302References: Upstream kernel (CVE-2023-20938)

  - In binder_vma_close of binder.c, there is a possible use after free due to improper locking. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-254837884References:
    Upstream kernel (CVE-2023-20928)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-33203. Reason: This candidate is a     reservation duplicate of CVE-2023-33203. Notes: All CVE users should reference CVE-2023-33203 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2023-2483)

  - Rejected reason: Duplicate of CVE-2023-3390. (CVE-2023-3117)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In binder_transaction_buffer_release of binder.c, there is a possible use after free due to improper input     validation. This could lead to local escalation of privilege with no additional execution privileges     needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid     ID: A-257685302References: Upstream kernel (CVE-2023-20938)

Note that Nessus relies on the presence of the package as reported by the vendor.
