The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0825 advisory.

  - kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

  - kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container     breakout (CVE-2021-4154)

  - kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

  - kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)

  - kernel: cgroups v1 release_agent feature may allow privilege escalation (CVE-2022-0492)

  - kernel: missing check in ioctl allows kernel memory read/write (CVE-2022-0516)

  - kernel: improper initialization of the flags member of the new pipe_buffer (CVE-2022-0847)

  - kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

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 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0763-1 advisory.

  - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

  - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

  - A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

  - An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The     RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive     information from kernel memory. (CVE-2022-25375)

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

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - A flaw was found in the way the 'flags' member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of kernel installed on the remote host is prior to 5.10.102-99.473. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-011 advisory.

    2024-07-03: CVE-2023-1582 was added to this advisory.

    AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The     Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on     AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26341)

This is done by default, and no administrator action is needed. (CVE-2021-26401)

    An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

    Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure. (CVE-2022-0001)

    Non-transparent sharing of branch predictor within a context in some Intel(r) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

    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)

    A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

    A use-after-free vulnerability was found in the tc_new_tfilter function in net/sched/cls_api.c in the     Linux kernel. The availability of local, unprivileged user namespaces allows privilege escalation.
    (CVE-2022-1055)

    The Amazon Linux kernel now enables, by default, a software mitigation for this issue, on all ARM-based     EC2 instance types. (CVE-2022-23960)

    A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet     Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
    (CVE-2022-2964)

    A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.
    This issue may allow a local attacker with user privilege to cause a denial of service. (CVE-2023-1582)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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