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