Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Native C extensions that interface with the Ruby VM are susceptible to memory corruption if Ruby VALUE references are garbage-collected while still in use by C functions. This can lead to use-after-free conditions, unexpected crashes, or arbitrary code execution. Future development in C extensions must strictly manage the visibility of Ruby values to the GC.
