Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-5691-1)

high Nessus Plugin ID 166286

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-5691-1 advisory.

 David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem 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-2022-2602)

 Snke Huster discovered that an integer overflow vulnerability existed in the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41674)

 Snke Huster discovered that the WiFi driver stack in the Linux kernel did not properly perform reference counting in some situations, 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-2022-42720)

 Snke Huster discovered that the WiFi driver stack in the Linux kernel did not properly handle BSSID/SSID lists in some situations. A physically proximate attacker could use this to cause a denial of service (infinite loop). (CVE-2022-42721)

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.
