The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6972-4 advisory.

    Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux Kernel contained a race     condition, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of     service (system crash). (CVE-2024-22099)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to     a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a     denial of service (system crash). (CVE-2024-24860)

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

  - sh: push-switch: Reorder cleanup operations to avoid use-after-free bug The original code puts     flush_work() before timer_shutdown_sync() in switch_drv_remove(). Although we use flush_work() to stop the     worker, it could be rescheduled in switch_timer(). As a result, a use-after-free bug can occur. The     details are shown below: (cpu 0) | (cpu 1) switch_drv_remove() | flush_work() | ... | switch_timer //     timer | schedule_work(&psw->work) timer_shutdown_sync() | ... | switch_work_handler // worker kfree(psw)     // free | | psw->state = 0 // use This patch puts timer_shutdown_sync() before flush_work() to mitigate     the bugs. As a result, the worker and timer will be stopped safely before the deallocate operations.
