Summary: An update for kernel-rt is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 Real Time (v. 7) - noarch, x86_64 Red Hat Enterprise Linux for Real Time for NFV (v. 7) - noarch, x86_64 3. Description: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: out of bound read in DVB connexant driver. (CVE-2015-9289) * kernel: Missing permissions check for request_key() destination allows local attackers to add keys to keyring without Write permission (CVE-2017-17807) * kernel: denial of service via ioctl call in network tun handling (CVE-2018-7191) * kernel: usb: missing size check in the __usb_get_extra_descriptor() leading to DoS (CVE-2018-20169) * kernel: perf_event_open() and execve() race in setuid programs allows a data leak (CVE-2019-3901) * kernel: brcmfmac frame validation bypass (CVE-2019-9503) * kernel: null-pointer dereference in hci_uart_set_flow_control (CVE-2019-10207) * kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command (CVE-2019-11884) * kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to denial of service (CVE-2019-12382) * kernel: use-after-free in arch/x86/lib/insn-eval.c (CVE-2019-13233) * kernel: integer overflow and OOB read in drivers/block/floppy.c (CVE-2019-14283) * kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service (CVE-2019-15916) * kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746) * kernel: oob memory read in hso_probe in drivers/net/usb/hso.c (CVE-2018-19985) * Kernel: net: weak IP ID generation leads to remote device tracking (CVE-2019-10638) * Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR (CVE-2019-10639) * kernel: ASLR bypass for setuid binaries due to late install_exec_creds() (CVE-2019-11190) 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.
