Description
The vulnerability allows a local user to perform service disruption.
Memory leak in the seq_file implementation in the SCSI procfs interface (sg.c) in Linux kernel 2.6.13 and earlier allows local users to cause a denial of service (memory consumption) via certain repeated reads from the /proc/scsi/sg/devices file, which is not properly handled when the next() iterator returns NULL or an error.
