Linux Kernel NULL Pointer Dereference Vulnerability in RTLA Tracing Tools

A vulnerability in the Linux kernel's RTLA (Real-Time Linux Analysis) tracing tools has been addressed. The issue involved a NULL pointer dereference, where the 'record' pointer was NULL but was being accessed. This error occurred in several files within the RTLA tracing tools, leading to potential crashes or undefined behavior. The vulnerability has been resolved by adding a tag to prevent dereferencing a NULL pointer.

Impact

Exploitation of this vulnerability could lead to a NULL pointer dereference, causing a crash or undefined behavior in the application.
