Sukrut Bellary

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a double free of the 'buf' in the error path of the fastrpc req mmap() function in the Linux kernel. This occurs because the fastrpc buffer is freed in fastrpc req munmap impl() if unmap is successful, but there is an unconditional call to fastrpc buf free() at the end, triggering the double free. The vulnerability may allow an attacker to impact the confidentiality, integrity, and availability of protected information. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
