Ubuntu 18.04 LTS : Linux kernel (Azure) vulnerabilities (USN-5865-1)

high Nessus Plugin ID 171365

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5865-1 advisory.

 It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 (V4L2) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20369)

 Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation (eIBRS) did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information. (CVE-2022-26373)

 David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

 Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64 processors, the branch predictor could by mis-trained for return instructions in certain circumstances. A local attacker could possibly use this to expose sensitive information. (CVE-2022-29900)

 Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64 processors, the Linux kernel's protections against speculative branch target injection attacks were insufficient in some circumstances. A local attacker could possibly use this to expose sensitive information. (CVE-2022-29901)

 It was discovered that the NILFS2 file system implementation in the Linux kernel did not properly deallocate memory in certain error conditions. An attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3646)

 Khalid Masum discovered that the NILFS2 file system implementation in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-3649)

 Hyunwoo Kim discovered that an integer overflow vulnerability existed in the PXA3xx graphics driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2022-39842)

 It was discovered that a race condition existed in the SMSC UFX USB driver implementation in the Linux kernel, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41849)

 It was discovered that a race condition existed in the Roccat HID driver in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41850)

 It was discovered that the USB monitoring (usbmon) component in the Linux kernel did not properly set permissions on memory mapped in to user space processes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43750)

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.
