A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash. #### Notes Author| Note ---|--- [sbeattie](<https://launchpad.net/~sbeattie>) | code execution is not possible unless mmap_min_addr is set to 0 (not the default)
