CVE-2026-68171

The vulnerability affects the Linux kernel on arm64 architectures, where the syscall register state can be manipulated by a tracer due to a failure to synchronize the saved value of register x0 with updates made during ptrace operations. This oversight may allow an attacker to bypass seccomp filtering and potentially execute unauthorized system calls, compromising system integrity. Organizations using arm64 Linux systems, particularly those relying on seccomp for security, should prioritize addressing this issue to mitigate risks associated with syscall manipulation.
