https://notcve.org/view.php?id=CVE-2022-21505
20 Apr 2023 — In the linux kernel, if IMA appraisal is used with the "ima_appraise=log" boot param, lockdown can be defeated with kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents setting "ima_appraise=log" from the boot param when Secure Boot is enabled, but this does not cover cases where lockdown is used without Secure Boot. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity, Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

CVE-2021-34981 – Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34981
21 Oct 2021 — Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the CMTP module. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. • https://www.zerodayinitiative.com/advisories/ZDI-21-1223 • CWE-415: Double Free •
