"The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-7317-1 advisory.

    George Chatzisofroniou and Panayiotis Kotzanikolaou discovered that wpa_supplicant and hostapd reused
    encryption elements in the PKEX protocol. An attacker could possibly use this issue to impersonate a
    wireless access point, and obtain sensitive information. (CVE-2022-37660)

    Daniel De Almeida Braga, Mohamed Sabt, and Pierre-Alain Fouque discovered that wpa_supplicant and hostapd
    were vulnerable to side channel attacks due to the cache access patterns. An attacker could possibly use
    this issue to obtain sensitive information. This issue only affected Ubuntu 20.04 LTS. (CVE-2022-23303,
    CVE-2022-23304)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
