Discussion
Linux Kernel 'oz_cdev_write()' Function Local Buffer Overflow Vulnerability
The Linux kernel is prone to a local buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.
Attackers can exploit this issue to execute arbitrary code with kernel privileges. Failed exploit attempts will likely crash the kernel, denying service to legitimate users.
