Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Logic inversions and incorrect permission checks during Cross-Program Invocations (CPI) could allow unauthorized programs to bypass write restrictions or execute privileged code inside the VM.
Sandbox Escape: Gaps in virtual address verification, instruction validation, and jump-target boundary checks in the eBPF/sBPF interpreter permit arbitrary bytecode execution to breach host boundaries.
Denial of Service: Parsing untrusted, variable-length peer gossip structures without strict boundary safeguards and overflow-protected arithmetic leads to memory exhaustion and crash loops.
