1. Summary:
An update for kernel-alt is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, noarch, ppc64le, s390x Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64, noarch, ppc64le
3. Description:
The kernel-alt packages provide the Linux kernel version 4.x.
Security Fix(es):
* kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow (CVE-2019-17666)
* kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence (CVE-2018-16871)
* kernel: Heap address information leak while using L2CAP_GET_CONF_OPT (CVE-2019-3459)
* kernel: Heap address information leak while using L2CAP_PARSE_CONF_RSP (CVE-2019-3460)
* kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command (CVE-2019-11884)
* kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception (CVE-2019-15030)
* kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service (CVE-2019-15916)
* kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c (CVE-2019-18805)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
