Vulnerability from github – Published: 2024-02-15 06:31 – Updated: 2024-10-28 21:30

Details

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

4.0 (Medium)
