The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6775-1 advisory.

    Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition     during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could     possibly use this to cause a denial of service (system crash). (CVE-2023-47233)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    - MAC80211 subsystem;

    - Tomoyo security module; (CVE-2024-26622, CVE-2023-52530)

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.
