CWEhttps://cwe.mitre.org/data/definitions/476.html

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.

Weakness

The product dereferences a pointer that it expects to be valid but is NULL.
