In the Linux kernel, the following vulnerability has been resolved:
scsi: qla1280: Fix kernel oops when debug level > 2
A null dereference or oops exception will eventually occur when qla1280.c driver is compiled with DEBUGQLA1280 enabled and qldebuglevel > 2. I think its clear from the code that the intention here is sgdmalen(s) not length of sgnext(s) when printing the debug info.
