CVE-2020-36788

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A use-after-free issue has been resolved in the Linux kernel, specifically in the drm/nouveau component. The nouveau bo init() function is backed by ttm bo init() and returns its error code to the caller. When nouveau bo init() fails, ttm bo init() invokes a destructor to de-initialize and free the memory. However, when nouveau bo init() returns an error, the gem object has already been released and the memory freed by nouveau bo del ttm().
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
