Executive brief
A memory corruption vulnerability exists in Qualcomm's audio framework fastboot command handler when processing untrusted user input. An attacker with physical access to a device in fastboot mode could exploit this flaw to execute arbitrary code or crash the audio subsystem, potentially compromising device integrity and availability.
Technical details
This vulnerability is a memory corruption issue (likely buffer overflow or use-after-free) in the fastboot command handler responsible for audio framework configuration. The flaw occurs when the handler processes untrusted user input without proper validation or bounds checking. Exploitation requires physical access to put the device into fastboot mode and send a malformed command; no network access or prior authentication is needed. A successful exploit could result in arbitrary code execution in the audio framework context or a denial-of-service condition. Qualcomm has issued a security bulletin addressing this issue in August 2026.
