CVE ID :CVE-2026-71980
Published : Aug. 17, 2026, 6:18 p.m. | 1 hour, 12 minutes ago
Description :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.
Severity: 8.7 | HIGH
