CVE-2010-3437
Published: 4 October 2010
Integer signedness error in the pkt_find_dev_from_minor function in drivers/block/pktcdvd.c in the Linux kernel before 2.6.36-rc6 allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and system crash) via a crafted index value in a PKT_CTRL_CMD_STATUS ioctl call.
From the Ubuntu Security Team
Dan Rosenberg discovered that the CD driver did not correctly check parameters. A local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy.
