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)
