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