Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: A critical ordering vulnerability allowed ptrace to run before seccomp checks, enabling user-space processes to bypass restricted system call filters by modifying registers post-evaluation. Developers modifying system call entry paths must preserve this strict evaluation ordering.
Memory Corruption: The lack of proper user-space boundary validation during stack walking allowed arbitrary pointer dereferences, risking kernel crashes or local privilege escalation. Future architectural tracing modifications must strictly enforce access_ok checks before memory retrieval.
Buffer Overflow: Unbounded heap copy operations during DCI diagnostic packet handling allowed out-of-bounds memory writes. Any driver-level communication channels parsing external diagnostic packets must explicitly validate payloads against destination buffer bounds.
