CVE-2019-10207: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 3.0, before 4.18.0 (fixed in 4.18.0); from 5.0, up to and including 5.4
