Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Resizing circular ring buffers without correctly accounting for element wrapping can lead to severe memory corruption and buffer overflows during reallocations. This poses a significant execution safety threat to the library.
Memory Safety: Parsing structured field parameters or priority values without strict bounds checks before pointer/index increments can lead to stack buffer overflows and out-of-bounds memory reads.
Input Validation: Improper validation of HTTP/3 header name characters could allow malformed or malicious header structures to bypass validation filters if lookup tables are not strictly enforced.
