CVE-2024-37985 is an information disclosure vulnerability in the Windows kernel affecting ARM-based Windows systems, including Windows 11 versions 22H2 and 23H2. The flaw is described as a side-channel issue associated with the FetchBench attack class and can allow a local, unauthenticated attacker to obtain unauthorized access to heap contents belonging to a privileged process. The vulnerability does not itself provide code execution or direct privilege escalation, but it can expose sensitive memory-resident information from higher-privileged contexts.
