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-6821-2 advisory.

It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition,     leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or     possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data     structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial     of service. (CVE-2023-7042)

It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer     dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service.
(CVE-2024-0841)

Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux Kernel contained a race     condition, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of     service (system crash). (CVE-2024-22099)

It was discovered that the MediaTek SoC Gigabit Ethernet driver in the Linux kernel contained a race     condition when stopping the device. A local attacker could possibly use this to cause a denial of service     (device unavailability). (CVE-2024-27432)
