CVE-2024-50057 Information

Description

In the Linux kernel the following vulnerability has been resolved:

usb: typec: tipd: Free IRQ only if it was requested before

In polling mode if no IRQ was requested there is no need to free it. Call devm_free_irq() only if client->irq is set. This fixes the warning caused by the tps6598x module removal:
