AI risk analysis
- Summary
- The vulnerability allows for potential race conditions in the handling of IRQs and workqueues in the Linux kernel, which could lead to privilege escalation or system instability.
- Exploitability
- Exploitation requires precise timing to schedule work after IRQs are disabled but before the device is freed, making it moderately difficult.
- Blast radius
- If exploited, the vulnerability could impact system stability and potentially allow for privilege escalation, affecting any system running the affected kernel version.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to the specific version 5.10.100 or later, as published in the advisory.

NVD description
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.
