Ubuntu 22.10 : Linux kernel vulnerabilities (USN-5970-1)

high Nessus Plugin ID 173374

Language:

Synopsis

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

Description

The remote Ubuntu 22.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5970-1 advisory.

 It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2022-2196)

 It was discovered that a race condition existed in the Xen network backend driver in the Linux kernel when handling dropped packets in certain circumstances. An attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-42328, CVE-2022-42329)

 Gerald Lee discovered that the USB Gadget file system implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4382)

 Jos Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did not properly protect against indirect branch prediction attacks in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-0045)

 It was discovered that a use-after-free vulnerability existed in the Advanced Linux Sound Architecture (ALSA) subsystem. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2023-0266)

 It was discovered that the io_uring subsystem in the Linux kernel contained a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-0469)

 It was discovered that the CIFS network file system implementation in the Linux kernel contained a user- after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-1195)

 It was discovered that the RNDIS USB driver in the Linux kernel contained an integer overflow vulnerability. A local attacker with physical access could plug in a malicious USB device to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-23559)

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.
