Linux Kernel Security Vulnerabilities
The Linux kernel version 4.8 has a security vulnerability. This vulnerability arises from the fact that arm64 ptrace does not synchronize origx0 with x0 at the system call entry. Especially when exiting via SECCOMPRETTRACE, this may allow the tracker to bypass seccomp or audit checks and manipula...
