CVE-2021-47289

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

Description A NULL pointer dereference issue has been resolved in the Linux kernel. The problem occurred when the acpi dev put() function was called on a possibly NULL pointer, which was not handled correctly by the helper inline function. This issue was caused by a change in the for each acpi dev match() function. To fix this, the acpi dev put() function has been modified to silently accept a NULL pointer.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
