Nessus は、ベンダーから報告されたパッケージの存在に依存していることに注意してください。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-151160 advisory.

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

    ceph: fix UAF in check_new_map() on session freed during unlock

    check_new_map() iterates mdsc->sessions[] and for each active session     drops mdsc->mutex to perform per-session operations.  The forced-close     path (rank removed from map) correctly takes a reference on s via     ceph_get_mds_session() before releasing mdsc->mutex, but three other     paths do not:

      Path A (address changed):  mutex_unlock  mutex_lock(&s->s_mutex)       Path B (reconnect):        mutex_unlock  send_mds_reconnect(mdsc, s)       Path C (active transition): mutex_unlock  mutex_lock(&s->s_mutex)

    Without the extra reference, another thread can acquire mdsc->mutex     during the unlock window, call __unregister_session() which drops the     last reference on s, and free it.  The original thread then accesses     freed memory via s->s_mutex.

    Fix by adding ceph_get_mds_session(s) before each mutex_unlock and     ceph_put_mds_session(s) after the corresponding mutex_lock, matching     the pattern already used in the forced-close path.

    Race timeline (Path A):

      Thread A (check_new_map)             Thread B (another map update         holds mdsc->mutex                      or session teardown)
      --------------------------           --------------------------       s = mdsc->sessions[i]       (refcount == 1, held only by        sessions[] array)

      mutex_unlock(&mdsc->mutex)
                                   --->    acquires mdsc->mutex
                                           __unregister_session(mdsc, s)                                              sessions[i] = NULL                                              ceph_put_mds_session(s)                                                refcount: 1 -> 0                                                kfree(s)  <--- freed!

      mutex_lock(&s->s_mutex)       UAF on freed s->s_mutex

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue 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.

    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     6.12.115-2~deb12u1.  This update additionally includes many more bug     fixes from stable updates 6.12.114 and 6.12.115.

    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 remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-9002-1 advisory.

    It was discovered that the io_uring subsystem in the Linux kernel did not properly handle canceled task     work when processing certain wait operations, leading to the operation being performed in the wrong task     context. A local attacker could possibly use this to cause a denial of service (system crash).

  - In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix DMA transfer     direction When CONFIG_DMA_API_DEBUG is selected, while running the crypto self test on the QAT crypto     algorithms, the function add_dma_entry() reports a warning similar to the one below, saying that     overlapping mappings are not supported. This occurs in tests where the input and the output scatter list     point to the same buffers (i.e. two different scatter lists which point to the same chunks of memory). The     logic that implements the mapping uses the flag DMA_BIDIRECTIONAL for both the input and the output     scatter lists which leads to overlapped write mappings. These are not supported by the DMA layer. Fix by     specifying the correct DMA transfer directions when mapping buffers. For in-place operations where the     input scatter list matches the output scatter list, buffers are mapped once with DMA_BIDIRECTIONAL,     otherwise input buffers are mapped using the flag DMA_TO_DEVICE and output buffers are mapped with     DMA_FROM_DEVICE. Overlapping a read mapping with a write mapping is a valid case in dma-coherent devices     like QAT. The function that frees and unmaps the buffers, qat_alg_free_bufl() has been changed accordingly     to the changes to the mapping function.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: cfg80211: Pass the PMK     in binary instead of hex Apparently the hex passphrase mechanism does not work on newer chips/firmware     (e.g. BCM4387). It seems there was a simple way of passing it in binary all along, so use that and avoid     the hexification. OpenBSD has been doing it like this from the beginning, so this should work on all     chips. Also clear the structure before setting the PMK. This was leaking uninitialized stack contents to     the device. (CVE-2023-53715)

  - In the Linux kernel, the following vulnerability has been resolved: posix-timers: Ensure timer ID search-     loop limit is valid posix_timer_add() tries to allocate a posix timer ID by starting from the cached ID     which was stored by the last successful allocation. This is done in a loop searching the ID space for a     free slot one by one. The loop has to terminate when the search wrapped around to the starting point. But     that's racy vs. establishing the starting point. That is read out lockless, which leads to the following     problem: CPU0 CPU1 posix_timer_add() start = sig->posix_timer_id; lock(hash_lock); ... posix_timer_add()     if (++sig->posix_timer_id < 0) start = sig->posix_timer_id; sig->posix_timer_id = 0; So CPU1 can observe a     negative start value, i.e. -1, and the loop break never happens because the condition can never be true:
    if (sig->posix_timer_id == start) break; While this is unlikely to ever turn into an endless loop as the     ID space is huge (INT_MAX), the racy read of the start value caught the attention of KCSAN and Dmitry     unearthed that incorrectness. Rewrite it so that all id operations are under the hash lock.
    (CVE-2023-53728)
