CVE-2023-54146
What it is
In the Linux kernel, the following vulnerability has been resolved: x86/kexec: Fix double-free of elf header buffer After b3e34a47f989 ("x86/kexec: fix memory leak of elf header buffer"), freeing image->elf_headers in the error path of crash_load_segments() is not needed because kimage_file_post_load_cleanup() will take care of that later. And not clearing it could result in a double-free. Drop the superfluous vfree() call at the error path of crash_load_segments().
