CVE-2026-68449

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

Description An infinite loop bug exists in the NCQ completion path of the sata dwc 460ex driver. When the tag mask variable contains only high bits, the inner while loop continues to left-shift the value until it overflows to 0. Once it reaches 0, the loop condition remains true indefinitely, leading to an infinite loop within the hardirq context while a spinlock is held.

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