Vulnerability CVE-2009-3288
Published: 2009-09-22   Modified: 2012-02-13

Description:
The sg_build_indirect function in drivers/scsi/sg.c in Linux kernel 2.6.28-rc1 through 2.6.31-rc8 uses an incorrect variable when accessing an array, which allows local users to cause a denial of service (kernel OOPS and NULL pointer dereference), as demonstrated by using xcdroast to duplicate a CD. NOTE: this is only exploitable by users who can open the cdrom device.

Type:

CWE-119

 (Improper Restriction of Operations within the Bounds of a Memory Buffer)
