In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: use chan timer to close channels in cleanup_listen() l2cap_chan_close() removes the channel from conn->chan_l, which must be done under conn->lock. cleanup_listen() runs under the parent sk_lock, so acquiring conn->lock would invert the established conn->lock -> chan->lock -> sk_lock order. Instead of calling l2cap_chan_close() directly, schedule l2cap_chan_timeout with delay 0 to close the channel asynchronously. The timeout handler already acquires conn->lock and chan->lock in the correct order. The timer is only armed when chan->conn is still set: if it is already NULL, l2cap_conn_del() has already processed this channel (l2cap_chan_del + l2cap_sock_teardown_cb + l2cap_sock_close_cb), so there is nothing left to do. If l2cap_conn_del() races in after the timer is armed, __clear_chan_timer() inside l2cap_chan_del() cancels it; if the timer has already fired, the handler returns harmlessly because chan->conn was cleared.

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 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8906-1 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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: use chan timer to
    close channels in cleanup_listen() l2cap_chan_close() removes the channel from conn->chan_l, which must be
    done under conn->lock. cleanup_listen() runs under the parent sk_lock, so acquiring conn->lock would
    invert the established conn->lock -> chan->lock -> sk_lock order. Instead of calling l2cap_chan_close()
    directly, schedule l2cap_chan_timeout with delay 0 to close the channel asynchronously. The timeout
    handler already acquires conn->lock and chan->lock in the correct order. The timer is only armed when
    chan->conn is still set: if it is already NULL, l2cap_conn_del() has already processed this channel
    (l2cap_chan_del + l2cap_sock_teardown_cb + l2cap_sock_close_cb), so there is nothing left to do. If
    l2cap_conn_del() races in after the timer is armed, __clear_chan_timer() inside l2cap_chan_del() cancels
    it; if the timer has already fired, the handler returns harmlessly because chan->conn was cleared.
    (CVE-2026-53358)

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-8781-1 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.

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.

  - Bluetooth: L2CAP: use chan timer to close channels in cleanup_listen() l2cap_chan_close() removes the     channel from conn->chan_l, which must be done under conn->lock. cleanup_listen() runs under the parent     sk_lock, so acquiring conn->lock would invert the established conn->lock -> chan->lock -> sk_lock order.
    Instead of calling l2cap_chan_close() directly, schedule l2cap_chan_timeout with delay 0 to close the     channel asynchronously. The timeout handler already acquires conn->lock and chan->lock in the correct     order. The timer is only armed when chan->conn is still set: if it is already NULL, l2cap_conn_del() has     already processed this channel (l2cap_chan_del + l2cap_sock_teardown_cb + l2cap_sock_close_cb), so there     is nothing left to do. If l2cap_conn_del() races in after the timer is armed, __clear_chan_timer() inside     l2cap_chan_del() cancels it; if the timer has already fired, the handler returns harmlessly because     chan->conn was cleared. (CVE-2026-53358)

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