When an oversized frame or untrusted input is copied into an underestimated heap allocation, adjacent heap memory can be overwritten, causing memory corruption. This class of vulnerability can lead to local privilege escalation where the vulnerable code path is reachable by a local, unprivileged actor and the process runs with elevated privileges. This submission intentionally contains **sanitized, non-actionable evidence** suitable for vendor triage. It does **not** include exploit code, raw addresses, offsets, or gadget/ROP information. [+] Exploit: - **Not provided.** Exploit code enabling privilege escalation is intentionally withheld. PoC: - **Omitted** from this disclosure to maintain responsible, non-actionable reporting. # Reproduce: - For vendor triage: provide the sanitized evidence report attached to this disclosure (sanitized ASan-like block + heap snapshots). - If the vendor requests further detail for internal validation, I can provide sanitized crash traces and safe pedagogical harnesses under an agreed disclosure channel and embargo. Don't share the result's from your tests, this can be danger for you!
