Title: Linux kernel 权限许可和访问控制问题漏洞 (CVE-2019-13272)
Description:In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.

Absolutely, I always choose Linux vulnerability, but then I had to choose different vulnerability else because I didn't know two people could do the same thing And then Having learned of this, I chose a different vulnerability, But because I had already solved that. This will include the report I did before and the new one I did later I've decided to include it separately Because I can't throw it away. Please  request that you check  both vulnerability report and come up with an idea
