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

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to
    achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending
    network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug
    and lack of error checking in agg_dequeue(). We recommend upgrading past commit
    8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

  - mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through
    5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.
    (CVE-2020-36158)

  - Integer overflow in the firmware for some Intel(R) Graphics Drivers for Windows * before version
    26.20.100.7212 and before Linux kernel version 5.5 may allow a privileged user to potentially enable an
    escalation of privilege via local access. (CVE-2020-12362)

  - usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because
    a transfer occurs without a reference, aka CID-056ad39ee925. (CVE-2020-12464)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent
    Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a
    network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,
    CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

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