In the Linux kernel, the following vulnerability has been resolved:
irqchip/ts4800: Fix missing chained handler cleanup on remove
The driver installs a chained handler for the parent interrupt during probe using irq_set_chained_handler_and_data(), but the remove function does not clear this handler. This leaves a dangling handler that may be called when the parent interrupt fires after the driver has been removed, potentially accessing freed memory and causing a kernel crash.
Additionally, the parent_irq obtained via irq_of_parse_and_map() is not stored, making it inaccessible in the remove function. Moreover, interrupt mappings created during probe are not properly disposed.
Fix this by:
- Saving parent_irq in probe - Clearing the chained handler with NULL in ts4800_ic_remove() - Disposing all IRQ mappings before domain removal to prevent resource leaks
