It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-148 advisory.

  - 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)

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