CVE-2022-49721

CVE-2022-49721 affects the Linux kernel (arm64) ftrace. The root cause is inconsistent handling of PLT entries when calling ftrace trampolines: ftrace_modify_call() can produce out-of-range branches, causing warnings and no code change, or replace the old branch with a BRK, risking a kernel panic...
