Description Adam Mariš 2016-05-05 09:39:08 UTC

An information leak vulnerability in wilc1000 module from staging portion of kernel tree was found in drivers/staging/wilc1000/wilc_wfi_cfgoperations.c. The 6-bytes stack object “mac” is not initialized but leaked via “nla_put”. This bug may result in leaks of sensitive kernel stack data.

Fedora doesn't build this module.  It should not be affected.

Comment 4 Vladis Dronov 2016-05-30 14:56:09 UTC

Statement:

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, 7 and MRG-2, as the code affected is in staging status and is not built with these products.
