Summary: found overlapping data buffer
Product: Drivers
Version: 2.5
Kernel Version: 2.6.29.3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: USB
AssignedTo: greg at kroah.com
ReportedBy: ettl.martin at gmx.de
Regression: No
Hello,
i detected an overlapping data buffer at file
"linux-2.6.29.3/drivers/usb/atm/usbatm.c"
For detection, i used the static code analysis tool cppcheck. It prints the
following message:
[linux-2.6.29.3/drivers/usb/atm/usbatm.c:1393]: (error) Overlapping data buffer
buffer
Take a loop at file usbatm.cat line 1393:
sprintf(buffer, "%s %2.2x", buffer, data[i]);
Here, var "buffer" is used by iteself, this is dangerous!!!!
Best regards
Ettl Martin
