CVE-2021-47276

The CVE-2021-47276 issue affects the Linux kernel’s ftrace on arm64, where -EINVAL could trigger ftrace_bug() to read the instruction pointer value from an invalid address, causing a kernel panic. The root cause was reading the ip address directly from memory when reporting the error. The remedy ...
