Summary
generated automatically from NVD dataThe dumpreg utility in Red Hat Linux 5.1 opens /dev/mem with read-write (O_RDWR) access. A local user can exploit this by redirecting file descriptor 1 (stdout) to the kernel, which causes the system to crash and results in a denial of service. The flaw is rated LOW severity with a CVSS v2.0 score of 2.1, and it requires local access and has no impact on confidentiality or integrity.
