Description
A flaw was found in the Linux kernel's irqchip/imgpdc driver. This vulnerability occurs because the driver fails to properly free allocated resources and remove interrupt handlers when the driver is removed. This oversight can lead to a use-after-free condition, where the system attempts to access memory that has already been released, potentially causing a kernel crash. Additionally, unremoved interrupt handlers could result in unexpected system behavior by accessing freed memory.
Mitigation
No mitigation is specified in collected source.
