CVE-2016-9754

Published: 05 January 2017

The ring_buffer_resize function in kernel/trace/ring_buffer.c in the profiling subsystem in the Linux kernel before 4.6.1 mishandles certain integer calculations, which allows local users to gain privileges by writing to the /sys/kernel/debug/tracing/buffer_size_kb file.

From the Ubuntu security team

It was discovered that an integer overflow existed in the trace subsystem of the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash).

Priority

Low

CVSS 3 base score: 7.8
