CVE-2011-4914: Linux kernel improper input validation vulnerability

Linux · Linux Kernel

The ROSE protocol implementation in the Linux kernel before 2.6.39 does not verify that certain data-length values are consistent with the amount of data sent, which might allow remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) via crafted data to a ROSE socket.
