CVE-2026-72384

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The driver for the ts4800 irqchip fails to clear a chained handler for the parent interrupt during the removal process. This occurs because the driver uses irq set chained handler and data() during probe but does not reset the handler in the remove function, leaving a dangling handler. If the parent interrupt fires after the driver is removed, it may access freed memory, leading to a kernel crash. Additionally, the parent irq obtained via irq of parse and map() is not stored, and interrupt mappings created during probe are not properly disposed, resulting in resource leaks.

Recommendations Update the Linux kernel to a version where the following fixes are implemented:
