CVE-2016-7425

Publication date 16 October 2016

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Cvss 3 Severity Score

7.8 · High

Score breakdown

The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code.

From the Ubuntu Security Team

Marco Grassi discovered that the driver for Areca RAID Controllers in the Linux kernel did not properly validate control messages. A local attacker could use this to cause a denial of service (system crash) or possibly gain privileges.
