Linux Kernel Stack Trace Recursion Vulnerability in Tracing Component

A vulnerability in the Linux kernel's tracing component can lead to infinite recursion when the kernel stack trace trigger is enabled. This issue occurs because the stack trace code interacts with RCU events, creating a loop where RCU calls the stack trace again. The vulnerability affects the stable versions of the Linux kernel.

Impact

Exploitation of this vulnerability can cause a stack overflow due to infinite recursion, potentially leading to a denial-of-service condition.

Remediation

Users can upgrade to the latest stable version of the Linux kernel to address this vulnerability.
