Описание
The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory by reading a message.
An information leak vulnerability in [llc] module was found in "net/llc/af_llc.c". The stack object "info" has a total size of 12 bytes. Its last byte is padding which is not initialized and leaked via put_cmsg().
Отчет
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, 7 and MRG-2 as the related code with the flaw is not present in the products listed.
