CVE-2010-3437

Publication date 4 October 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

This was assigned to bradf and I re-assigned it to myself for minor fixups and so the tools will find things.
