  script_set_attribute(attribute:"description", value:
"The remote NewStart CGSL host, running version MAIN 6.02, has kernel packages installed that are affected by multiple
vulnerabilities:

  - In the Linux kernel before 5.4.16, a race condition in tty->disc_data handling in the slip and slcan line
    discipline could lead to a use-after-free, aka CID-0ace17d56824. This affects drivers/net/slip/slip.c and
    drivers/net/can/slcan.c. (CVE-2020-14416)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the
    way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or
    escalate their privileges on the system. (CVE-2022-0330)

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends
    a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have
    access to the TIPC network. (CVE-2022-0435)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of
    actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()
    function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This
    flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn
    by its CNA. Further investigation showed that it was not a security issue. Notes: none. (CVE-2022-3542)

  - A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability
    is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the
    component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this
    issue. The identifier VDB-211045 was assigned to this vulnerability. (CVE-2022-3545)

  - A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the sch_sfb
    enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed)
    into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of
    service. (CVE-2022-3586)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this
    vulnerability is the function intr_callback of the file drivers/net/usb/r8152.c of the component BPF. The
    manipulation leads to logging of excessive data. The attack can be launched remotely. It is recommended to
    apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211363.
    (CVE-2022-3594)

  - drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information
    from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
    (CVE-2022-40768)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused
    by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-
    space client to corrupt the monitor's internal memory. (CVE-2022-43750)

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