CVE-2014-4323
HighSummary
The mdp_lut_hw_update function in the MDP display driver for Linux kernel 3.x does not validate certain start and length values within an ioctl call, allowing attackers to gain privileges via a crafted application.
Risk Assessment
The lack of validation in the ioctl call poses a privilege escalation risk, potentially leading to unauthorized access to the system.
Recommendation
It is recommended to update the Linux kernel to a version that includes fixes for this vulnerability and to implement additional validation mechanisms in applications using this driver.
