CVE-2022-50879

A NULL pointer dereference was found in objtool, a build-time tool used during Linux kernel compilation. When find_insn() returns NULL on failure, the code proceeds to dereference the NULL pointer, causing objtool to crash with a segmentation fault during kernel build operations.

This is not a runtime kernel vulnerability. Objtool is a userspace build-time tool that runs during kernel compilation to validate object files. A crash in objtool affects the kernel build process only and has no impact on running systems. This should not be classified as a kernel security vulnerability.
