In the Linux kernel, the following vulnerability has been resolved: iavf: Fix handling of dummy receive descriptors Fix memory leak caused by not handling dummy receive descriptor properly. iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive descriptors. Without this patch, when the hardware writes a dummy descriptor, iavf would not free the page allocated for the previous receive buffer. This is an unlikely event but can still happen.

The version of kernel installed on the remote host is prior to 5.10.135-122.509. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2025-086 advisory.

    An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

    A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel     lockdown was enabled (CVE-2022-21505)

    A flaw was found in hw. Aliases in the branch predictor may cause some AMD processors to predict the wrong     branch type, potentially leading to information disclosure. (CVE-2022-23825)

    Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

    A flaw was found in hw. The unprotected alternative channel of return branch target prediction in some     Intel(R) Processors may allow an authorized user to enable information disclosure via local access.
    (CVE-2022-28693)

    A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary     speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29900)

    Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their     retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can     hijack return instructions to achieve arbitrary speculative code execution under certain     microarchitecture-dependent conditions. (CVE-2022-29901)

    A memory access flaw was found in the Linux kernel's XEN hypervisor for the virtual machine. This flaw     allows a local user to crash the system or potentially escalate their privileges on the system.
    (CVE-2022-36123)

    An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

    A memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses     the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash     the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
    (CVE-2022-36946)

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.

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

  - In the Linux kernel, the following vulnerability has been resolved: iavf: Fix handling of dummy receive     descriptors Fix memory leak caused by not handling dummy receive descriptor properly. iavf_get_rx_buffer     now sets the rx_buffer return value for dummy receive descriptors. Without this patch, when the hardware     writes a dummy descriptor, iavf would not free the page allocated for the previous receive buffer. This is     an unlikely event but can still happen.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The version of kernel installed on the remote host is prior to 5.4.209-116.363. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-034 advisory.

    An out-of-bounds write flaw was found in the Linux kernel's framebuffer-based console driver     functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data. This flaw allows a     local user to crash or potentially escalate their privileges on the system. (CVE-2021-33655)

    A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel     lockdown was enabled (CVE-2022-21505)

    A heap buffer overflow flaw was found in the Linux kernel's Netfilter subsystem in the way a user provides     incorrect input of the NFT_DATA_VERDICT type. This flaw allows a local user to crash or potentially     escalate their privileges on the system. (CVE-2022-34918)

    An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

    A memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses     the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash     the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
