CVE-2022-23091 (GCVE-0-2022-23091)
Vulnerability from cvelistv5 – Published: 2024-02-15 05:11 – Updated: 2025-02-13 16:29
VLAI?
Summary
A particular case of memory sharing is mishandled in the virtual memory system. This is very similar to SA-21:08.vm, but with a different root cause.
An unprivileged local user process can maintain a mapping of a page after it is freed, allowing that process to read private data belonging to other processes or the kernel.
Severity ?
4 (Medium)
