Possible memory leak in acm_probe not freeing (acm->country_codes) on error path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Bug Report Filed: https://bugzilla.kernel.org/show_bug.cgi?id=88521
Linux Version [3.17-rc1]
Configuration: Default configuration for x86

Function Source:
http://lxr.free-electrons.com/source/drivers/usb/class/cdc-acm.c#L1404

In function (acm_probe) in file (drivers/usb/class/cdc-acm.c):

Pointer (acm->country_codes) gets allocated in line (1404) and freed
in lines (1414, 1424) if the call to function (device_create_file)
fails (i < 0). However, if the conditions at (1413 and 1422) evaluates
to false, the function (acm_probe) exists without freeing the pointer
(acm->country_codes). Thus, causing a memory leak.


Thanks,
Ahmed
