Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel vulnerabilities (USN-6172-1)

high Nessus Plugin ID 183722

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6172-1 advisory.

 It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1076)

 It was discovered that the Real-Time Scheduling Class implementation in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1077)

 It was discovered that the ASUS HID driver in the Linux kernel did not properly handle device removal, leading to a use-after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash). (CVE-2023-1079)

 It was discovered that the Xircom PCMCIA network device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1670)

 It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory).
 (CVE-2023-1859)

 Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.
 (CVE-2023-1998)

 It was discovered that the BigBen Interactive Kids' gamepad driver in the Linux kernel did not properly handle device removal, leading to a use- after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash). (CVE-2023-25012)

 It was discovered that a use-after-free vulnerability existed in the HFS+ file system implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2023-2985)

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.

Solution

Update the affected kernel package.
