CVE-2022-50879 [LOW] CWE-476 kernel: objtool: Fix SEGFAULT
kernel: objtool: Fix SEGFAULT
In the Linux kernel, the following vulnerability has been resolved:
objtool: Fix SEGFAULT
find_insn() will return NULL in case of failure. Check insn in order
to avoid a kernel Oops for NULL pointer dereference.
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.
Statement: 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 clas
