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-6704-3 advisory.

  - In the Linux kernel before 5.17, drivers/phy/tegra/xusb.c mishandles the tegra_xusb_find_port_node return     value. Callers expect NULL in the error case, but an error pointer is used. (CVE-2023-23000)

  - A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw     exists within the handling of SMB2_SESSION_SETUP commands. The issue results from the lack of control of     resource consumption. An attacker can leverage this vulnerability to create a denial-of-service condition     on the system. (CVE-2023-32247)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_setelem_catchall_deactivate() function checks whether the     catch-all set element is active in the current generation instead of the next generation before freeing     it, but only flags it inactive in the next generation, making it possible to free the element multiple     times, leading to a double free vulnerability. We recommend upgrading past commit     b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7. (CVE-2024-1085)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

  - A race condition was found in the Linux kernel's scsi device driver in lpfc_unregister_fcf_rescan()     function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or     denial of service issue. (CVE-2024-24855)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
