Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the VIA watchdog driver where an unnamed resource allocation can lead to a critical boot hang. The driver uses
allocate resource() to reserve a memory region for the watchdog control register, but fails to name the allocated resource. This results in an invalid entry in the kernel resource tree under /proc/iomem on x86 platforms. During the boot process, this unnamed resource can cause failures in resource lookups and conflict checks, ultimately leading to a system hang.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
