    In the Linux kernel, the following vulnerability has been resolved:x86/vmscape: Add conditional IBPB     mitigation

    VMSCAPE is a vulnerability that exploits insufficient branch predictor isolation between a guest and a     userspace hypervisor (like QEMU). Existing mitigations already protect kernel/KVM from a malicious guest.
    Userspace can additionally be protected by flushing the branch predictors after a VMexit.

    Since it is the userspace that consumes the poisoned branch predictors, conditionally issue an IBPB after     a VMexit and before returning to userspace. Workloads that frequently switch between hypervisor and     userspace will incur the most overhead from the new IBPB.

    This new IBPB is not integrated with the existing IBPB sites. For instance, a task can use the existing     speculation control prctl() to get an IBPB at context switch time. With this implementation, the IBPB is     doubled up: one at context switch and another before running userspace. The intent is to integrate and     optimize these cases post-embargo.[ dhansen: elaborate on suboptimal IBPB solution ] (CVE-2025-40300)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

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

  - fbcon: fix integer overflow in fbcon_do_set_font Fix integer overflow vulnerabilities in     fbcon_do_set_font() where font size calculations could overflow when handling user-controlled font     parameters. The vulnerabilities occur when: 1. CALC_FONTSZ(h, pitch, charcount) performs h * pith *     charcount multiplication with user-controlled values that can overflow. 2. FONT_EXTRA_WORDS * sizeof(int)     + size addition can also overflow 3. This results in smaller allocations than expected, leading to buffer     overflows during font data copying. Add explicit overflow checking using check_mul_overflow() and     check_add_overflow() kernel helpers to safety validate all size calculations before allocation.
    (CVE-2025-39967)

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

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6053 advisory.
