Answer in brief
CVE-2026-71980 records a Unknown severity vulnerability in Belledonne Communications bcg729 1.1.2 Out-of-Bounds Read via decodeSIDframe(). The current sources do not mark it as known exploited. The current feed maps BelledonneCommunications/bcg729 (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Belledonne Communications bcg729 through 1.1.2 contains an out-of-bounds read vulnerability in the decodeSIDframe() function in src/cng.c that allows unauthenticated network-adjacent attackers to trigger a heap read beyond buffer boundaries by sending a zero-length comfort-noise RTP payload. A zero-length payload causes an integer underflow in the uint8_t filter order calculation, which wraps to 255 and is clamped to 10, causing the function to unconditionally read 11 bytes from a zero-byte buffer, resulting in media process termination or silent consumption of adjacent heap memory as reflection coefficients.
