GHSA-76G6-5V2W-PW2H

Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-01-10 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

vhost-vdpa: fix use after free in vhost_vdpa_probe()

The put_device() calls vhost_vdpa_release_dev() which calls ida_simple_remove() and frees "v". So this call to ida_simple_remove() is a use after free and a double free.

Severity ?

7.8 (High)
