Description Dhananjay Arunesh 2019-09-25 16:27:11 UTC

A vulnerability was found in the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c
allows attackers to obtain sensitive information from kernel stack memory
because tos and flags fields are not initialized.

Comment 1 Justin M. Forbes 2019-09-25 19:48:07 UTC

This was fixed for Fedora with the 5.2.14 stable updates.

Comment 2 Dave Baker 2019-09-27 15:03:12 UTC

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1756412]

Comment 4 Wade Mealing 2019-12-10 04:55:57 UTC

Red Hat products are not affected as they do not contain the source code required to leak the information to userspace.
