Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-5415-1)

high Nessus Plugin ID 161063

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5415-1 advisory.

 Jeremy Cline discovered a use-after-free in the nouveau graphics driver of the Linux kernel during device removal. A privileged or physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-27820)

 Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.
 (CVE-2021-26401)

 David Bouman discovered that the netfilter subsystem in the Linux kernel did not initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory).
 (CVE-2022-1016)

 It was discovered that the MMC/SD subsystem in the Linux kernel did not properly handle read errors from SD cards in certain situations. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-20008)

 It was discovered that the USB gadget subsystem in the Linux kernel did not properly validate interface descriptor requests. An attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2022-25258)

 It was discovered that the Remote NDIS (RNDIS) USB gadget implementation in the Linux kernel did not properly validate the size of the RNDIS_MSG_SET command. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-25375)

 It was discovered that the ST21NFCA NFC driver in the Linux kernel did not properly validate the size of certain data in EVT_TRANSACTION events. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-26490)

 It was discovered that the Xilinx USB2 device gadget driver in the Linux kernel did not properly validate endpoint indices from the host. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-27223)

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.
