CVE-2012-2745

New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

The copy_creds function in kernel/cred.c in the Linux kernel before 3.3.2 provides an invalid replacement session keyring to a child process, which allows local users to cause a denial of service (panic) via a crafted application that uses the fork system call.
