Linux · Linux Kernel · CVE-2021-47425
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A resource leak in the Linux kernel has been resolved. The issue occurs when `acpi i2c find adapter by handle()` calls `bus find device()`, which takes a reference on the adapter that is never released, resulting in a reference count leak and rendering the adapter unremovable. The fix involves putting the adapter after creating the client in the same manner as it is done for OF.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
