* kernel: Rogue cross-process SSBD shutdown. Linux scheduler logical bug allows an attacker to turn off the SSBD protection. (CVE-2020-10766)

* kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS is available. (CVE-2020-10767)

* kernel: Indirect branch speculation can be enabled after it was force-disabled by the PR_SPEC_FORCE_DISABLE prctl command. (CVE-2020-10768)

* kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in drivers/net/wireless/marvell/mwifiex/scan.c (CVE-2020-12653)

* kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function in drivers/net/wireless/marvell/mwifiex/wmm.c (CVE-2020-12654)

* Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario (CVE-2020-12888)

* kernel: lockdown: bypass through ACPI write via efivar_ssdt (CVE-2019-20908)

* kernel: lockdown: bypass through ACPI write via acpi_configfs (CVE-2020-15780)
