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-5851-1 advisory.

  - A vulnerability, which was classified as problematic, has been found in Linux Kernel. This issue affects     the function unix_sock_destructor/unix_release_sock of the file net/unix/af_unix.c of the component BPF.
    The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The     associated identifier of this vulnerability is VDB-211043. (CVE-2022-3543)

  - A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects     the function l2cap_recv_acldata of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The     manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. VDB-211918 is the     identifier assigned to this vulnerability. (CVE-2022-3619)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this     vulnerability is the function follow_page_pte of the file mm/gup.c of the component BPF. The manipulation     leads to race condition. The attack can be launched remotely. It is recommended to apply a patch to fix     this issue. The identifier VDB-211921 was assigned to this vulnerability. (CVE-2022-3623)

  - A buffer overflow flaw was found in the Linux kernel Broadcom Full MAC Wi-Fi driver. This issue occurs     when a user connects to a malicious USB device. This can allow a local user to crash the system or     escalate their privileges. (CVE-2022-3628)

  - A vulnerability, which was classified as critical, was found in Linux Kernel. Affected is the function     l2cap_conn_del of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads     to use after free. It is recommended to apply a patch to fix this issue. The identifier of this     vulnerability is VDB-211944. (CVE-2022-3640)

  - drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use-     after-free if a physically proximate attacker removes a USB device while calling open(), aka a race     condition between ufx_ops_open and ufx_usb_disconnect. (CVE-2022-41849)

  - roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition     and resultant use-after-free in certain situations where a report is received while copying a     report->value is in progress. (CVE-2022-41850)

  - There is an infoleak vulnerability in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_parse_conf_req     function which can be used to leak kernel pointers remotely. We recommend upgrading past commit     https://github.com/torvalds/linux/commit/b1a2cd50c0357f243b7435a732b4e62ba3157a2e     https://www.google.com/url (CVE-2022-42895)

  - An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.18 before 5.18.18. fs/ksmbd/smb2pdu.c     lacks length validation in the non-padding case in smb2_write. (CVE-2022-47940)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race     condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

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