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: driver core: location: Free struct     acpi_pld_info *pld before return false struct acpi_pld_info *pld should be freed before the return of     allocation failure, to prevent memory leak, add the ACPI_FREE() to fix it. (CVE-2023-53211)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-138 advisory.

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

    drm: Fix potential null-ptr-deref due to drmm_mode_config_init() (CVE-2022-50556)

    A double-free vulnerability was found in the handling of IORING_OP_SOCKET operation with io_uring on the     Linux kernel. (CVE-2023-1032)

    Due to a type confusion during initializations, the tun and tap sockets in the Linux Kernel have their     socket UID hardcoded to 0, i.e. root. While it will be often correct, as TUN/TAP devices require     CAP_NET_ADMIN, it may not always be the case. The socket UID may be used for network filtering and     routing, thus TUN/TAP sockets may be incorrectly managed, potentially bypassing network filters based on     UID. (CVE-2023-1076)

    kernel: Type confusion in pick_next_rt_entity(), which can result in memory corruption. (CVE-2023-1077)

    A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the     way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate     their privileges on the system. (CVE-2023-1118)

    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 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)

    An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker     can trigger a race condition that results in a fill_kobj_path out-of-bounds write. (CVE-2023-45863)
