CVE-2011-4914
CWE-20Published: June 21, 2012· Updated: Jun 16, 2026
6.4
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2011-4914 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
