Summary
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
