====================================================== Name: CVE-2009-3288 Status: Candidate URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3288 Reference: MLIST:[linux-kernel] 20090902 [BUG] 2.6.31-rc8 readcd Oops Reference: URL:http://lkml.org/lkml/2009/9/3/1 Reference: MLIST:[linux-kernel] 20090903 [PATCH] sg: fix oops in the error path in sg_build_indirect() Reference: URL:http://lkml.org/lkml/2009/9/3/107 Reference: MLIST:[oss-security] 20090904 CVE request: kernel: NULL pointer dereference in sg_build_indirect() Reference: URL:http://www.openwall.com/lists/oss-security/2009/09/03/4 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.
