Description

The vulnerability allows a local user to read and manipulate data.

Multiple integer signedness errors in the sg_scsi_ioctl function in scsi_ioctl.c for Linux 2.6.x allow local users to read or modify kernel memory via negative integers in arguments to the scsi ioctl, which bypass a maximum length check before calling the copy_from_user and copy_to_user functions.

Mitigation
Install update from vendor's repository.

Vulnerable software versions

Linux kernel: All versions
