CVE-2026-22188 - Panda3D <= 1.10.16 Deploy-Stub Stack Exhaustion via Unbounded alloca()
CVE ID : CVE-2026-22188
Published : Jan. 7, 2026, 9:16 p.m. | 40 minutes ago
Description : Panda3D versions up to and including 1.10.16 deploy-stub contains a denial of service vulnerability due to unbounded stack allocation. The deploy-stub executable allocates argv_copy and argv_copy2 using alloca() based directly on the attacker-controlled argc value without validation. Supplying a large number of command-line arguments can exhaust stack space and propagate uninitialized stack memory into Python interpreter initialization, resulting in a reliable crash and undefined behavior.
Severity: 6.9 | MEDIUM
