Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Memory Corruption: The SPIR-V image operations are highly prone to memory corruption via out-of-bounds coordinate offsets and lane calculations. Bypassing robustness protections can lead to arbitrary write or read capabilities.

Integer Overflow: Signed/unsigned comparison mismatches and unchecked arithmetic on pixel unpack offsets allow attackers to bypass buffer size validation, resulting in severe heap corruption.

Use-After-Free: Vulkan descriptor sets and image views lack adequate reference or liveness tracking, allowing sampling operations to dereference deleted host-allocated objects or pointers.
