The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system. (CVE-2017-2636, Important)

Red Hat would like to thank Alexander Popov for reporting this issue.
