The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6707-4 advisory.

  - 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)

  - In the Linux kernel, the following vulnerability has been resolved: pwm: Fix out-of-bounds access in     of_pwm_single_xlate() With args->args_count == 2 args->args[2] is not defined. Actually the flags are     contained in args->args[1]. (CVE-2024-26599)

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

The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6707-1 advisory.

  - 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)
