CVE-2022-34890

Kernel information disclosure via unvalidated pointer dereference

Published Jul 15, 2022 · Updated Aug 3, 2024

Information disclosure in Parallels Tools in Parallels Desktop 17.1.1 (51537) allows local users to read sensitive kernel data. Parallels Tools dereferences a user-supplied value as a pointer without validating that the pointer addresses permitted memory. Exploitation requires low-privileged code execution in a guest system; the disclosure can support a vulnerability chain that executes code in the kernel context.
