The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - rtc: cmos: Fix event handler registration ordering issue Because acpi_install_fixed_event_handler()     enables the event automatically on success, it is incorrect to call it before the handler routine passed     to it is ready to handle events. Unfortunately, the rtc-cmos driver does exactly the incorrect thing by     calling cmos_wake_setup(), which passes rtc_handler() to acpi_install_fixed_event_handler(), before     cmos_do_probe(), because rtc_handler() uses dev_get_drvdata() to get to the cmos object pointer and the     driver data pointer is only populated in cmos_do_probe(). This leads to a NULL pointer dereference in     rtc_handler() on boot if the RTC fixed event happens to be active at the init time. To address this issue,     change the initialization ordering of the driver so that cmos_wake_setup() is always called after a     successful cmos_do_probe() call. While at it, change cmos_pnp_probe() to call cmos_do_probe() after the     initial if () statement used for computing the IRQ argument to be passed to cmos_do_probe() which is     cleaner than calling it in each branch of that if () (local variable irq can be of type int, because it     is passed to that function as an argument of type int). Note that commit 6492fed7d8c9 (rtc: rtc-cmos: Do     not check ACPI_FADT_LOW_POWER_S0) caused this issue to affect a larger number of systems, because     previously it only affected systems with ACPI_FADT_LOW_POWER_S0 set, but it is present regardless of that     commit. (CVE-2022-48953)

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