In the Linux kernel, the following vulnerability has been resolved: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page nvmet_execute_disc_get_log_page() validates only the dword alignment of the host-supplied Log Page Offset (lpo). The 64-bit offset is then added to a small kzalloc'd buffer that holds the discovery log page and the result is passed straight to nvmet_copy_to_sgl(), which memcpy()s data_len bytes out to the host with no source-side bound check: u64 offset = nvmet_get_log_page_offset(req->cmd); /* 64-bit host */ size_t data_len = nvmet_get_log_page_len(req->cmd); /* 32-bit host */ ... if (offset & 0x3) { ... } /* only check */ ... alloc_len = sizeof(*hdr) + entry_size * discovery_log_entries(req); buffer = kzalloc(alloc_len, GFP_KERNEL); ... status = nvmet_copy_to_sgl(req, 0, buffer + offset, data_len); The Discovery controller is unauthenticated -- nvmet_host_allowed() returns true unconditionally for the discovery subsystem -- so the call is reachable pre-authentication by any TCP/RDMA/FC peer that can reach the nvmet target. With a discovery log page of ~1 KiB, an attacker requesting up to 4 KiB starting at offset == alloc_len reads the next slab page out and gets its content returned over the fabric (an empirical run on a default nvmet-tcp loopback target leaked 81 canonical kernel pointers in one Get Log Page response). Pointing the offset at unmapped kernel memory faults the in-kernel memcpy and crashes (or panics, on panic_on_oops=1) the target host instead. The attacker-controlled source-side offset pattern "nvmet_copy_to_sgl(req, 0, buffer + ATTACKER_OFFSET, ...)" is unique to nvmet_execute_disc_get_log_page in the entire nvmet codebase: every other Get Log Page handler in admin-cmd.c either ignores lpo (and silently starts every response at offset 0) or tracks a local destination offset with a fixed source pointer. Validate the host-supplied offset against the log page size, cap the copy length to what is actually available, and zero-fill any remainder of the host transfer buffer. The zero-fill matches the existing short-response pattern in nvmet_execute_get_log_changed_ns() (admin-cmd.c) and prevents leaking transport SGL contents when the host asks for more bytes than the log page contains.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098911 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page

    nvmet_execute_disc_get_log_page() validates only the dword alignment     of the host-supplied Log Page Offset (lpo).  The 64-bit offset is then     added to a small kzalloc'd buffer that holds the discovery log page     and the result is passed straight to nvmet_copy_to_sgl(), which     memcpy()s data_len bytes out to the host with no source-side bound     check:

        u64 offset      = nvmet_get_log_page_offset(req->cmd);  /* 64-bit host */         size_t data_len = nvmet_get_log_page_len(req->cmd);     /* 32-bit host */         ...
        if (offset & 0x3) { ... }                               /* only check */         ...
        alloc_len = sizeof(*hdr) + entry_size * discovery_log_entries(req);
        buffer = kzalloc(alloc_len, GFP_KERNEL);
        ...
        status = nvmet_copy_to_sgl(req, 0, buffer + offset, data_len);

    The Discovery controller is unauthenticated -- nvmet_host_allowed()     returns true unconditionally for the discovery subsystem -- so the call     is reachable pre-authentication by any TCP/RDMA/FC peer that can reach     the nvmet target.  With a discovery log page of ~1 KiB, an attacker     requesting up to 4 KiB starting at offset == alloc_len reads the next     slab page out and gets its content returned over the fabric (an     empirical run on a default nvmet-tcp loopback target leaked 81     canonical kernel pointers in one Get Log Page response).  Pointing the     offset at unmapped kernel memory faults the in-kernel memcpy and     crashes (or panics, on panic_on_oops=1) the target host instead.

    The attacker-controlled source-side offset pattern     nvmet_copy_to_sgl(req, 0, buffer + ATTACKER_OFFSET, ...) is unique     to nvmet_execute_disc_get_log_page in the entire nvmet codebase: every     other Get Log Page handler in admin-cmd.c either ignores lpo (and     silently starts every response at offset 0) or tracks a local     destination offset with a fixed source pointer.

    Validate the host-supplied offset against the log page size, cap the     copy length to what is actually available, and zero-fill any remainder     of the host transfer buffer.  The zero-fill matches the existing     short-response pattern in nvmet_execute_get_log_changed_ns()     (admin-cmd.c) and prevents leaking transport SGL contents when the     host asks for more bytes than the log page contains.

    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:

An update of the linux package has been released.

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

  - nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page nvmet_execute_disc_get_log_page()     validates only the dword alignment of the host-supplied Log Page Offset (lpo). The 64-bit offset is then     added to a small kzalloc'd buffer that holds the discovery log page and the result is passed straight to     nvmet_copy_to_sgl(), which memcpy()s data_len bytes out to the host with no source-side bound check: u64     offset = nvmet_get_log_page_offset(req->cmd); /* 64-bit host */ size_t data_len =     nvmet_get_log_page_len(req->cmd); /* 32-bit host */ ... if (offset & 0x3) { ... } /* only check */ ...
    alloc_len = sizeof(*hdr) + entry_size * discovery_log_entries(req); buffer = kzalloc(alloc_len,     GFP_KERNEL); ... status = nvmet_copy_to_sgl(req, 0, buffer + offset, data_len); The Discovery controller     is unauthenticated -- nvmet_host_allowed() returns true unconditionally for the discovery subsystem -- so     the call is reachable pre-authentication by any TCP/RDMA/FC peer that can reach the nvmet target. With a     discovery log page of ~1 KiB, an attacker requesting up to 4 KiB starting at offset == alloc_len reads the     next slab page out and gets its content returned over the fabric (an empirical run on a default nvmet-tcp     loopback target leaked 81 canonical kernel pointers in one Get Log Page response). Pointing the offset at     unmapped kernel memory faults the in-kernel memcpy and crashes (or panics, on panic_on_oops=1) the target     host instead. The attacker-controlled source-side offset pattern nvmet_copy_to_sgl(req, 0, buffer +     ATTACKER_OFFSET, ...) is unique to nvmet_execute_disc_get_log_page in the entire nvmet codebase: every     other Get Log Page handler in admin-cmd.c either ignores lpo (and silently starts every response at offset     0) or tracks a local destination offset with a fixed source pointer. Validate the host-supplied offset     against the log page size, cap the copy length to what is actually available, and zero-fill any remainder     of the host transfer buffer. The zero-fill matches the existing short-response pattern in     nvmet_execute_get_log_changed_ns() (admin-cmd.c) and prevents leaking transport SGL contents when the host     asks for more bytes than the log page contains. (CVE-2026-64320)

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