A vulnerability, which was classified as problematic, was found in Linux Kernel (Operating System) (affected version not known). This affects some unknown functionality of the component SG_IO SCSI IOCTL. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:
The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume.
The weakness was presented 12/22/2011 by Paolo Bonzini (oss-sec). It is possible to read the advisory at openwall.com. This vulnerability is uniquely identified as CVE-2011-4127 since 10/18/2011. Attacking locally is a requirement. A authentication is required for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK.
