CVE-2023-52520: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: platform/x86: think-lmi: Fix reference leak If a duplicate attribute is found using kset_find_obj(), a reference to that attribute is returned which needs to be disposed accordingly using kobject_put(). Move the setting name validation into a separate function to allow for this change without having to duplicate the cleanup code for this setting. As a side note, a very similar bug was fixed in commit 7295a996fdab ("platform/x86: dell-sysman: Fix reference leak"), so it seems that the bug was copied from that driver. Compile-tested only.

Affected products

• Linux Linux Kernel: from 5.14, before 5.15.136 (fixed in 5.15.136); from 5.16, before 6.1.59 (fixed in 6.1.59); from 6.2, before 6.5.8 (fixed in 6.5.8); version 6.6 only
