CVE-2017-8831

Published: 08 May 2017

The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.11.5 allows local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a "double fetch" vulnerability.

From the Ubuntu security team

Pengfei Wang discovered that a race condition existed in the NXP SAA7164 TV Decoder driver for the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Priority

Low

CVSS 3 base score: 6.4
