It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-430 advisory.

  - An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access     to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES     emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege     escalation). This depends on a race condition through which userspace can replace an instruction before     the #VC handler reads it. (CVE-2023-46813)

  - An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an     io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

  - A flaw was found in KVM. An improper check in svm_set_x2apic_msr_interception() may allow direct access to     host x2apic msrs when the guest resets its apic, potentially leading to a denial of service condition.
    (CVE-2023-5090)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an     event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory     locations outside of the allocated buffer. We recommend upgrading past commit     32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

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