Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the
dma-buf/sw-sync component in the Linux kernel, where an incorrect replacement of spin unlock irqrestore() with spin unlock irq() for both sync debugfs show() and sync print obj() functions caused a lockdep complaint about an inconsistent lock state warning. This occurred since commit a6aa8fca4d79. The sync print obj() function is called from sync debugfs show(), and using plain spin {lock,unlock}() for sync print obj() resolves the issue, as sync debugfs show() already uses spin {lock,unlock} irq(). The vulnerability may allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
