AI-suggested
A fix has been implemented in the Linux kernel to address this issue by adding kfree() calls in the remove functions. Users should update to the patched kernel version once available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.
Description
In the Linux kernel, the following vulnerability has been resolved: mfd: sm501: Fix potential memory leaks during remove The memory allocated for struct sm501_devdata in sm501_pci_probe() and sm501_plat_probe() is not freed by the corresponding remove functions sm501_pci_remove() and sm501_plat_remove(). Fix that by adding a call to kfree().
