Linux Kernel yurex_read Privilege Escalation Vulnerability [CVE-2018-16276]
CVE Number – CVE-2018-16276
A vulnerability in the yurex_read function of the Linux Kernel could allow a local attacker to gain elevated privileges or cause a denial of service (DoS) condition on a targeted system.
The vulnerability is due to an out-of-bounds access condition in the yurex_read function, as defined in the drivers/usb/misc/yurex.c source code file of the affected software. Because of the incorrect bounds checking in the yurex USB driver by the affected software, an attacker could exploit this vulnerability by executing a program that submits malicious input to the targeted system. A successful exploit could allow the attacker to gain elevated privileges on the system or cause the affected software to crash, resulting in a DoS condition.
Kernel.org confirmed the vulnerability and released software updates.
-
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement may reduce the likelihood of a successful exploit.
