| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the
scx dump state() function related to unsafe locking when built with CONFIG PREEMPT RT=y. Specifically, the dump lock can become a sleepable spinlock that does not disable interrupts, leading to inconsistent interrupt handling and a potential deadlock scenario. The issue arises from the use of rq lock/unlock() which has been replaced with rq lock irqsave/irqrestore() to address this problem. The stack trace indicates the issue occurs during interrupt handling within the kernel, potentially impacting system stability.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
