In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double-free in SMB2_close() replay A response-bearing attempt can return a replayable error and free its response buffer. If SMB2_close_init() fails before the next send, cleanup retains the previous buffer type and frees that response again. Reset response bookkeeping before each attempt to prevent the stale free.

The remote Ubuntu 24.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8760-1 advisory.

The remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8727-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

Tenable has extracted the preceding description block directly from the Ubuntu 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 remote Ubuntu 24.04 LTS / 26.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8726-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

    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:

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.

  - smb: client: fix double-free in SMB2_close() replay A response-bearing attempt can return a replayable     error and free its response buffer. If SMB2_close_init() fails before the next send, cleanup retains the     previous buffer type and frees that response again. Reset response bookkeeping before each attempt to     prevent the stale free. (CVE-2026-64597)

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

An update of the linux package has been released.
