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

  - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of     ttys could lead to a use-after-free. (CVE-2020-36557)

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

The remote OracleVM system is missing necessary patches to address security updates:

  - In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum     address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP     platforms. This is related to a capability check for the wrong task. (CVE-2019-9213)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of     ttys could lead to a use-after-free. (CVE-2020-36557)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

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

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2741-1 advisory.

    The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security bugfixes.

    The following security bugs were fixed:

    - CVE-2022-36946: Fixed an incorrect packet trucation operation which could lead to denial of service     (bnc#1201940).
    - CVE-2022-29581: Fixed improper update of reference count in net/sched that could cause root privilege     escalation (bnc#1199665).
    - CVE-2022-20166: Fixed several possible memory safety issues due to unsafe operations (bsc#1200598).
    - CVE-2020-36558: Fixed a race condition involving VT_RESIZEX which could lead to a NULL pointer     dereference and general protection fault (bnc#1200910).
    - CVE-2020-36557: Fixed a race condition between the VT_DISALLOCATE ioctl and closing/opening of TTYs that     could lead to a use-after-free (bnc#1201429).
    - CVE-2021-33655: Fixed an out of bounds write by ioctl cmd FBIOPUT_VSCREENINFO (bnc#1201635).
    - CVE-2021-33656: Fixed an out of bounds write related to ioctl cmd PIO_FONT (bnc#1201636).
    - CVE-2022-21505: Fixed a kernel lockdown bypass via IMA policy (bsc#1201458).
    - CVE-2022-1462: Fixed an out-of-bounds read flaw in the TTY subsystem (bnc#1198829).
    - CVE-2022-1116: Fixed an integer overflow vulnerability in io_uring which allowed a local attacker to     escalate privileges to root (bnc#1199647).- CVE-2022-2318: Fixed a use-after-free vulnerability in the     timer handler in Rose subsystem that allowed unprivileged attackers to crash the system (bsc#1201251).
    - CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed multiple potential data leaks with     Block and Network devices when using untrusted backends (bsc#1200762).


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.
