CVE-2025-68303
In the Linux kernel, the following vulnerability has been resolved: platform/x86: intel: punit_ipc: fix memory corruption This passes the address of the pointer "&punit_ipcdev" when the intent was to pass the pointer itself "punit_ipcdev" (without the ampersand). This means that the: complete(&ipcdev->cmd_complete); in intel_punit_ioc() will write to a wrong memory address corrupting it.
