## Description
In the Linux kernel, the following vulnerability has been resolved:
acpi: typec: ucsi: Introduce a ->poll\_cci method
For the ACPI backend of UCSI the UCSI "registers" are just a memory copy
of the register values in an opregion. The ACPI implementation in the
BIOS ensures that the opregion contents are synced to the embedded
controller and it ensures that the registers (in particular CCI) are
synced back to the opregion on notifications. While there is an ACPI call
that syncs the actual registers to the opregion there is rarely a need to
do this and on some ACPI implementations it actually breaks in various
interesting ways.
The only reason to force a sync from the embedded controller is to poll
CCI while notifications are disabled. Only the ucsi core knows if this
is the case and guessing based on the current command is suboptimal, i.e.
leading to the following spurious assertion splat:
WARNING: CPU: 3 PID: 76 at drivers/usb/typec/ucsi/ucsi.c:1388
ucsi\_reset\_ppm+0x1b4/0x1c0 [typec\_ucsi]
CPU: 3 UID: 0 PID: 76 Comm: kworker/3:0 Not tainted 6.12.11-200.fc41.x86\_64

Hardware name: LENOVO 21D0/LNVNB161216, BIOS J6CN45WW 03/17/2023
Workqueue: events\_long ucsi\_init\_work [typec\_ucsi]
RIP: 0010:ucsi\_reset\_ppm+0x1b4/0x1c0 [typec\_ucsi]
Call Trace:

kthread+0xd2/0x100
ret\_from\_fork+0x34/0x50
ret\_from\_fork\_asm+0x1a/0x30
Thus introduce a ->poll\_cci() method that works like ->read\_cci() with an
additional forced sync and document that this should be used when polling
with notifications disabled. For all other backends that presumably don't
have this issue use the same implementation for both methods.
