- 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)

- 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)
