Doc Text:	A flaw was found in the Linux kernel's USB Type-C Qualcomm PMIC driver. A race condition exists where the `reset_work` can be scheduled by an interrupt request (IRQ) handler after interrupts are disabled but before the associated memory is freed. This can lead to a use-after-free vulnerability, potentially allowing a local attacker to cause a denial of service or achieve arbitrary code execution.	Story Points:	---

Description OSIDB Bzimport 2026-09-16 11:08:25 UTC

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: qcom-pmic: cancel reset_work on stop

pdphy_stop() disables IRQs but leaves reset_work pending.  If the IRQ
handler schedules it just before disable_irq(), the work runs after
remove() frees the struct via devm.

Call cancel_work_sync() after disabling IRQs to close the window.

This issue was found by an in-house static analysis tool.
