CVE-2026-31399

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contained a use-after-free issue within the nd async device register() function during asynchronous initialization. This occurred when device add() failed, leading to a drop in the device reference count to zero before the parent pointer was accessed. The issue was identified using KASAN by Dingisoul and addressed by holding a reference to the parent pointer to ensure it remains valid regardless of the outcome of device add().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
