RHSA-2019:2945: Important: kpatch-patch security update

First published: Tue Oct 01 2019(Updated: )

This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.<br>Security fix(es):<br><li> If the Wake-up on Wireless LAN functionality is configured in the brcmfmac driver, which only works with Broadcom FullMAC chipsets, a malicious event frame can be constructed to trigger a heap buffer overflow in the brcmf_wowl_nd_results() function. This vulnerability can be exploited by compromised chipsets to compromise the host, or when used in combination with another brcmfmac driver flaw (CVE-2019-9503), can be used remotely. This can result in a remote denial of service (DoS). Due to the nature of the flaw, a remote privilege escalation cannot be fully ruled out. (CVE-2019-9500)</li> For more details about the security issue(s), including the impact, a CVSS score, acknowledgements, and other related information, refer to the CVE page(s) listed in the References section.
