Era 300 Firmware
Monthly
Heap-based buffer overflow vulnerability in Sonos Era 300 speakers that allows unauthenticated, network-adjacent attackers to execute arbitrary code with high severity (CVSS 8.8). The flaw exists in ALAC (Apple Lossless Audio Codec) data processing where insufficient length validation enables buffer overflow conditions. This vulnerability poses significant risk as it requires no authentication, no user interaction, and can be exploited by any attacker on the local network segment to achieve remote code execution in the context of the anacapa user.
