Name of the Vulnerable Software and Affected Versions
Red Hat Linux kernel versions 2.2.x
Description
The issue affects the Red Hat Linux kernel, allowing local users to cause a denial of service or potentially disrupt the confidentiality, integrity, and availability of protected information. Exploitation can be done locally. Specifically, the Linux kernel 2.2.x is vulnerable to a denial of service attack by using the
mmap() function with a PROT READ parameter to access non-readable memory pages through the /proc/pid/mem interface.Recommendations
For Red Hat Linux kernel version 2.2.x, consider updating to a newer version to mitigate the risk, as no specific fix is provided for this version.
As a temporary workaround, consider restricting local access to minimize the risk of exploitation.
Avoid using the
mmap() function with a PROT READ parameter to access non-readable memory pages until the issue is resolved.Exploit
