Details

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

lib/string_helpers: fix not adding strarray to device's resource list

Add allocated strarray to device's resource list. This is a must to automatically release strarray when the device disappears.

Without this fix we have a memory leak in the few drivers which use devm_kasprintf_strarray().

Severity

5.5 (Medium)
