Description

platform/x86: intel: punit_ipc: fix memory corruption

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
