Recurring patterns

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

Buffer Overflow: Concurrency issues during audio mode switching can cause buffer overflows in the resampler cache if state resets and mutex locks are not strictly synchronized.
Denial of Service: Race conditions between the LVGL rendering task and main application threads can cause a crash if GIF resources are destroyed before the rendering task is hidden and locked.
Denial of Service: Performing slow UI updates on synchronous execution paths during high-throughput activities like OTA upgrades can block network processing, leading to receive buffer overflows.
