Technical Description
In the Linux kernel, the following vulnerability has been resolved:
i2c: designware: Fix handling of real but unexpected device interrupts
Commit c7b79a752871 ("mfd: intel-lpss: Add Intel Alder Lake PCH-S PCI
IDs") caused a regression on certain Gigabyte motherboards for Intel
Alder Lake-S where system crashes to NULL pointer dereference in
i2c_dw_xfer_msg() when system resumes from S3 sleep state ("deep").
I was able to debug the issue on Gigabyte Z690 AORUS ELITE and made
following notes:
- Issue happens when resuming from S3 but not when resuming from
"s2idle"
- PCI device 00:15.0 == i2c_designware.0 is already in D0 state when
system enters into pci_pm_resume_noirq() while all other i2c_designware
PCI devices are in D3. Devices were runtime suspended and in D3 prior
entering into suspend
- Interrupt comes after pci_pm_resume_noirq() when device interrupts are
re-enabled
- According to register dump the interrupt really comes from the
i2c_designware.0. Controller is
