CVE-2022-49329

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A NULL pointer dereference issue has been identified in the Linux kernel, specifically in the vduse component when accessing the control device's msg timeout attribute via sysfs. This issue occurs because the control device lacks drvdata, leading to a NULL pointer dereference. The problem is evident when the msg timeout show function is called, resulting in a kernel NULL pointer dereference error.

Recommendations To resolve this issue, do not create the unneeded attribute for the control device anymore, as this attribute is the cause of the NULL pointer dereference.
