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: x86/resctrl: Clear staged_config[]     before and after it is used As a temporary storage, staged_config[] in rdt_domain should be cleared before     and after it is used. The stale value in staged_config[] could cause an MSR access error. Here is a     reproducer on a system with 16 usable CLOSIDs for a 15-way L3 Cache (MBA should be disabled if the number     of CLOSIDs for MB is less than 16.) : mount -t resctrl resctrl -o cdp /sys/fs/resctrl mkdir     /sys/fs/resctrl/p{1..7} umount /sys/fs/resctrl/ mount -t resctrl resctrl /sys/fs/resctrl mkdir     /sys/fs/resctrl/p{1..8} An error occurs when creating resource group named p8: unchecked MSR access error:
    WRMSR to 0xca0 (tried to write 0x00000000000007ff) at rIP: 0xffffffff82249142 (cat_wrmsr+0x32/0x60) Call     Trace: <IRQ> __flush_smp_call_function_queue+0x11d/0x170 __sysvec_call_function+0x24/0xd0     sysvec_call_function+0x89/0xc0 </IRQ> <TASK> asm_sysvec_call_function+0x16/0x20 When creating a new     resource control group, hardware will be configured by the following process: rdtgroup_mkdir()     rdtgroup_mkdir_ctrl_mon() rdtgroup_init_alloc() resctrl_arch_update_domains()     resctrl_arch_update_domains() iterates and updates all resctrl_conf_type whose have_new_ctrl is true.
    Since staged_config[] holds the same values as when CDP was enabled, it will continue to update the     CDP_CODE and CDP_DATA configurations. When group p8 is created, get_config_index() called in     resctrl_arch_update_domains() will return 16 and 17 as the CLOSIDs for CDP_CODE and CDP_DATA, which will     be translated to an invalid register - 0xca0 in this scenario. Fix it by clearing staged_config[] before     and after it is used. [reinette: re-order commit tags] (CVE-2023-53169)

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 ALAS2023-2023-148 advisory.

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

    KVM: VMX: Do _all_ initialization before exposing /dev/kvm to userspace (CVE-2022-49932)

    A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve     local privilege escalation.

    The perf_group_detach function did not check the event's siblings' attach_state before calling     add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching     from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability.

    We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. (CVE-2023-2235)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4. (CVE-2023-30456)
