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-6972-1 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)
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:
- SuperH RISC architecture;
- User-Mode Linux (UML);
- GPU drivers;
- MMC subsystem;
- Network drivers;
- PHY drivers;
- Pin controllers subsystem;
- Xen hypervisor drivers;
- GFS2 file system;
- Core kernel;
- Bluetooth subsystem;
- IPv4 networking;
- IPv6 networking;
- HD-audio driver;
- ALSA SH drivers; (CVE-2024-26903, CVE-2024-35835, CVE-2023-52644, CVE-2024-39292, CVE-2024-36940, CVE-2024-26600, CVE-2023-52629, CVE-2024-35955, CVE-2023-52760, CVE-2023-52806, CVE-2024-39484, CVE-2024-26679, CVE-2024-26654, CVE-2024-36901, CVE-2024-26687, CVE-2023-52470)
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.
