CVE-2017-8924: Debian Linux

Medium severity, CVSS 4.6. EPSS: 0.5% chance of exploitation in the next 30 days.

The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only
• Linux Linux Kernel: up to and including 4.10.3
