In the Linux kernel, the following vulnerability has been resolved: can: esd_usb: kill anchored URBs before freeing netdevs esd_usb_disconnect() frees each CAN netdev with free_candev() inside its per-netdev loop and only calls unlink_all_urbs(dev) afterwards. The per-netdev private data (struct esd_usb_net_priv) is embedded in the net_device allocation returned by alloc_candev(), so once free_candev() has run, dev->nets[i] points to freed memory. unlink_all_urbs() then dereferences the freed dev->nets[i] to kill the per-netdev TX anchor (usb_kill_anchored_urbs(&priv->tx_submitted)), clear active_tx_jobs, and reset priv->tx_contexts[]. Reorder the teardown so the anchored URBs are killed before the netdevs are freed, matching other CAN/USB drivers in the same directory such as ems_usb, usb_8dev and mcba_usb, which unregister, then unlink, then free: unregister the netdevs first (which stops their TX queues), call unlink_all_urbs(dev) once, then free the netdevs. This issue was found by an in-house static analysis tool.

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1792751247 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: mmmremap.c: avoid pointless     invalidate_range_start/end on mremap(old_size=0) If an mremap() syscall with old_size=0 ends up in     move_page_tables(), it will call invalidate_range_start()/invalidate_range_end() unnecessarily, i.e. with     an empty range. This causes a WARN in KVM's mmu_notifier. In the past, empty ranges have been diagnosed to     be off-by-one bugs, hence the WARNing. Given the low (so far) number of unique reports, the benefits of     detecting more buggy callers seem to outweigh the cost of having to fix cases such as this one, where     userspace is doing something silly. In this particular case, an early return from move_page_tables() is     enough to fix the issue. (CVE-2022-49077)

  - In the Linux kernel, the following vulnerability has been resolved: virtio_console: eliminate anonymous     module_init & module_exit Eliminate anonymous module_init() and module_exit(), which can lead to confusion     or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init     and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map)     ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log)     calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1     initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned     0 after 74 usecs (CVE-2022-49100)

  - In the Linux kernel, the following vulnerability has been resolved: mtd: Fix device name leak when     register device failed in add_mtd_device() There is a kmemleak when register device failed: unreferenced     object 0xffff888101aab550 (size 8): comm insmod, pid 3922, jiffies 4295277753 (age 925.408s) hex dump     (first 8 bytes): 6d 74 64 30 00 88 ff ff mtd0.... backtrace: [<00000000bde26724>]

(CVE-2022-50566)

  - In the Linux kernel, the following vulnerability has been resolved: media: dvb-frontends: fix leak of     memory fw (CVE-2022-50664)

  - In the Linux kernel, the following vulnerability has been resolved: acct: fix potential integer overflow     in encode_comp_t() The integer overflow is descripted with following codes: > 317 static comp_t     encode_comp_t(u64 value) > 318 { > 319 int exp, rnd; ...... > 341 exp <<= MANTSIZE; > 342 exp += value; >     343 return exp; > 344 } Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of     'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535. (CVE-2022-50749)

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

    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.

  - can: esd_usb: kill anchored URBs before freeing netdevs esd_usb_disconnect() frees each CAN netdev with     free_candev() inside its per-netdev loop and only calls unlink_all_urbs(dev) afterwards. The per-netdev     private data (struct esd_usb_net_priv) is embedded in the net_device allocation returned by     alloc_candev(), so once free_candev() has run, dev->nets[i] points to freed memory. unlink_all_urbs() then     dereferences the freed dev->nets[i] to kill the per-netdev TX anchor     (usb_kill_anchored_urbs(&priv->tx_submitted)), clear active_tx_jobs, and reset priv->tx_contexts[].
    Reorder the teardown so the anchored URBs are killed before the netdevs are freed, matching other CAN/USB     drivers in the same directory such as ems_usb, usb_8dev and mcba_usb, which unregister, then unlink, then     free: unregister the netdevs first (which stops their TX queues), call unlink_all_urbs(dev) once, then     free the netdevs. This issue was found by an in-house static analysis tool. (CVE-2026-64585)

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