Description OSIDB Bzimport 2026-09-24 17:09:28 UTC 
In the Linux kernel, the following vulnerability has been resolved:

watchdog: lenovo_se10_wdt: Fix use-after-free and resource leak risk

Review by sashiko.dev highlighted potential use after free and resource
leak instances.

Set se10_pdev to null to prevent use after free

Remove DMI call back and instead directly call
se10_create_platform_device. Handle error cases appropriately
