The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0723 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as     destination (CVE-2024-0646)

    * kernel: sctp: fail if no bound addresses can be used for a given scope (CVE-2023-1074)

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 4.14.309-231.529. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1987 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    net: sched: fix memory leak in tcindex_set_parms (CVE-2022-50396)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0458)

    Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root.This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

    A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to     root.We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

    When plain IBRS is enabled (not enhanced IBRS), the logic in spectre_v2_user_select_mitigation()     determines that STIBP is not needed. The IBRS bit implicitly protects against cross-thread branch     targetinjection. However, with legacy IBRS, the IBRS bit is cleared on returning to userspace for     performance reasons which leaves userspace threads vulnerable to cross-thread branch target injection     against which STIBP protects. (CVE-2023-1998)

    A use-after-free flaw was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in the SCSI     sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information.
    (CVE-2023-2162)

    In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

    A use-after-free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw     could allow a local user to cause a denial of service. (CVE-2023-2985)

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the fbcon_set_font, since there are no checks in place, a shift-out-of-     bounds occurs, leading to undefined behavior and possible denial of service. (CVE-2023-3161)

    An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux     kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)
