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

  - netfilter: br_netfilter: do not check confirmed bit in br_nf_local_in() after confirm When send a     broadcast packet to a tap device, which was added to a bridge, br_nf_local_in() is called to confirm the     conntrack. If another conntrack with the same hash value is added to the hash table, which can be     triggered by a normal packet to a non-bridge device, the below warning may happen. ------------[ cut here     ]------------ WARNING: CPU: 1 PID: 96 at net/bridge/br_netfilter_hooks.c:632 br_nf_local_in+0x168/0x200     CPU: 1 UID: 0 PID: 96 Comm: tap_send Not tainted 6.17.0-rc2-dirty #44 PREEMPT(voluntary) RIP:

If confirm() does not insert the conntrack entry and return NF_DROP, the warning may also occur.
    There is no need to reserve the WARN_ON_ONCE, just remove it. (CVE-2025-39894)

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

    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.

    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)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     6.1.153-1~deb11u1.  Starting with this version, modules are signed     with an ephemeral key on all architectures, and the broken pktcdvd     driver is disabled.  This version additionally includes many more bug     fixes from stable updates 6.1.141-6.1.153.

    We recommend that you upgrade your linux-6.1 packages.

    For the detailed security status of linux-6.1 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.1
