RedHat: RHSA-2020-1016:01 Moderate: kernel security, bug fix,
Summary
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
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: denial of service in arch/powerpc/kernel/signal_32.c and
arch/powerpc/kernel/signal_64.c via sigreturn() system call
(CVE-2019-13648)
* 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: (powerpc) incomplete Spectre-RSB mitigation leads to information
exposure (CVE-2019-18660)
* 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)
