CVE-2024-56569
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix regression with module command in stack_trace_filter
When executing the following command:
The current mod command causes a null pointer dereference. While commit 0f17976568b3f ("ftrace: Fix regression with module command in stack_trace_filter") has addressed part of the issue, it left a corner case unhandled, which still results in a kernel crash.
