In the Linux kernel, the following vulnerability has been resolved: vfio/mlx5: Fix racy bitfields and tighten struct layout Bitfield operations are not atomic, they use a read-modify-write pattern, therefore we should be careful not to pack bitfields that can be concurrently updated into the same storage unit. This split takes a binary approach: flags that are only modified pre/post open/close remain bitfields, flags modified from user action, including actions that reach across to another device (ex. reset) use dedicated storage units. Note mlx5_vhca_page_tracker.status is relocated to fill the alignment hole this split exposes. Bitfield justifications: migrate_cap: written only in mlx5vf_cmd_set_migratable() at probe chunk_mode: written only in mlx5vf_cmd_set_migratable() at probe mig_state_cap: written only in mlx5vf_cmd_set_migratable() at probe Dedicated storage units: mdev_detach: written in the VF attach/detach event notifier mlx5fv_vf_event() at runtime log_active: written in mlx5vf_start_page_tracker()/ mlx5vf_stop_page_tracker() during runtime dirty tracking deferred_reset: written in mlx5vf_state_mutex_unlock()/ mlx5vf_pci_aer_reset_done() during runtime reset handling is_err: set by tracker error handling and dirty-log polling at runtime object_changed: set by tracker event handling and cleared by dirty-log polling at runtime

    Linux 6.12 has been packaged for Debian 12 bookworm as linux-6.12.
    This provides a supported upgrade path for systems that currently use     kernel packages from the bookworm-backports suite.

    There is no need to upgrade systems using Linux 6.1, as that kernel     version will also continue to be supported in the LTS period.

    The apt full-upgrade command will *not* automatically install the     updated kernel packages.  You should explicitly install one of the     following metapackages first, as appropriate for your system:

        linux-image-6.12-amd64         linux-image-6.12-arm64         linux-image-6.12-arm64-16k         linux-image-6.12-armmp         linux-image-6.12-armmp-lpae         linux-image-6.12-cloud-amd64         linux-image-6.12-cloud-arm64         linux-image-6.12-powerpc64le         linux-image-6.12-powerpc64le-64k         linux-image-6.12-rt-amd64         linux-image-6.12-rt-arm64         linux-image-6.12-rt-armmp

    For example, if the command uname -r currently shows     6.12.95+deb12-amd64, you should install linux-image-6.12-amd64.

    This backport does not include the following binary packages:

        bpftool hyperv-daemons intel-sdsi libcpupower-dev libcpupower1         linux-cpupower linux-libc-dev linux-perf rtla usbip

    Older versions of most of those are built from the linux source     package in Debian 12.

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

    For Debian 12 bookworm, these problems have been fixed in version     6.12.100-1~deb12u1.  This update also fixes several bugs reported to     Debian.  It additionally includes many more bug fixes from stable     updates 6.12.96-6.12.100.

    We recommend that you upgrade your linux-6.12 packages.

    For the detailed security status of linux-6.12 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.12

    Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://wiki.debian.org/LTS     Attachment:

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4723 advisory.

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

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.100-1.

    We recommend that you upgrade your linux packages.

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

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/

Tenable has extracted the preceding description block directly from the Debian 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.

  - vfio/mlx5: Fix racy bitfields and tighten struct layout Bitfield operations are not atomic, they use a     read-modify-write pattern, therefore we should be careful not to pack bitfields that can be concurrently     updated into the same storage unit. This split takes a binary approach: flags that are only modified     pre/post open/close remain bitfields, flags modified from user action, including actions that reach across     to another device (ex. reset) use dedicated storage units. Note mlx5_vhca_page_tracker.status is relocated     to fill the alignment hole this split exposes. Bitfield justifications: migrate_cap: written only in     mlx5vf_cmd_set_migratable() at probe chunk_mode: written only in mlx5vf_cmd_set_migratable() at probe     mig_state_cap: written only in mlx5vf_cmd_set_migratable() at probe Dedicated storage units: mdev_detach:
    written in the VF attach/detach event notifier mlx5fv_vf_event() at runtime log_active: written in     mlx5vf_start_page_tracker()/ mlx5vf_stop_page_tracker() during runtime dirty tracking deferred_reset:
    written in mlx5vf_state_mutex_unlock()/ mlx5vf_pci_aer_reset_done() during runtime reset handling is_err:
    set by tracker error handling and dirty-log polling at runtime object_changed: set by tracker event     handling and cleared by dirty-log polling at runtime (CVE-2026-64472)

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