Ubuntu 16.04 ESM / 18.04 LTS : Linux kernel vulnerabilities (USN-5418-1)

high Nessus Plugin ID 161060

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5418-1 advisory.

 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)

 Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen backend to gain access to memory pages of a guest VM or cause a denial of service in the guest.
 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038, CVE-2022-23039, CVE-2022-23040, CVE-2022-23042)

 It was discovered that the USB Gadget file system interface in the Linux kernel contained 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-2022-24958)

 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 USB SR9700 ethernet device driver for the Linux kernel did not properly validate the length of requests from the device. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-26966)

 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.
