Vulnerability from gsd
Modified
2023-12-13 01:19
Details
KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
