Name of the Vulnerable Software and Affected Versions
Linux kernel version 6.18.0-rc3
Description
An issue in the Enhanced Error Handling (EEH) driver for powerpc leads to recursive locking. The function
eeh handle normal event() acquires the pci lock rescan remove() lock before calling eeh pe bus get(), which then attempts to acquire the same lock internally. This nested locking disrupts normal EEH event handling paths and results in broken PCI error reporting and improper EEH event triggering.Recommendations
For version 6.18.0-rc3, update the kernel to a version where
eeh handle normal event() is corrected to call eeh pe bus get nolock() when the lock is already held and pci lock rescan remove() is restored to the correct position after eeh pe bus get().Exploit
