CVE-2026-80974

Estado: RecibidaSin puntuar—

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().
