In the Linux kernel, the following vulnerability has been resolved:

platform/x86: intel: punitipc: fix memory corruption

This passes the address of the pointer "&punitipcdev" when the intent was to pass the pointer itself "punitipcdev" (without the ampersand). This means that the:

complete(&ipcdev->cmdcomplete);

in intelpunitioc() will write to a wrong memory address corrupting it.
