Intel Core I7 8557u Firmware

Out-of-bounds read in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via adjacent access.

Improper input validation in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable denial of service via adjacent access.

Improper input validation in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via adjacent access.

Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable denial of service via local access.

Exposure of resource to wrong sphere in BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

Improper input validation in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.

Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially cause a denial of service via local access.

Processor optimization removal or modification of security-critical code for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with SGX may allow an unprivileged user to potentially enable information disclosure via physical access.

Hardware debug modes and processor INIT setting that allow override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel(R) TXT may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

Out-of-bounds write in the BIOS authenticated code module for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.

Improper access control in the BIOS authenticated code module for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.

Logic error in BIOS firmware for 8th, 9th and 10th Generation Intel(R) Core(TM) Processors may allow an unauthenticated user to potentially enable escalation of privilege, denial of service and/or information disclosure via physical access.

Improper initialization in BIOS firmware for 8th, 9th and 10th Generation Intel(R) Core(TM) Processor families may allow an unauthenticated user to potentially enable escalation of privilege via local access.

Improper buffer restrictions in BIOS firmware for 7th, 8th, 9th and 10th Generation Intel(R) Core(TM) Processor families may allow an authenticated user to potentially enable escalation of privilege and/or denial of service via local access.

Improper conditions check in multiple Intel® Processors may allow an authenticated user to potentially enable partial escalation of privilege, denial of service and/or information disclosure via local access.

Improper conditions check in voltage settings for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege and/or information disclosure via local access.

Insufficient access control in protected memory subsystem for SMM for 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor families; Intel(R) Xeon(R) Processor E3-1500 v5 and v6 families; Intel(R) Xeon(R) E-2100 and E-2200 Processor families with Intel(R) Processor Graphics may allow a privileged user to potentially enable information disclosure via local access.

Insufficient memory protection in Intel(R) 6th Generation Core Processors and greater, supporting TXT, may allow a privileged user to potentially enable escalation of privilege via local access.

Insufficient memory protection in Intel(R) 6th Generation Core Processors and greater, supporting SGX, may allow a privileged user to potentially enable escalation of privilege via local access.

Insufficient access control in protected memory subsystem for Intel(R) SGX for 6th, 7th, 8th, 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Xeon(R) Processor E3-1500 v5, v6 Families; Intel(R) Xeon(R) E-2100 & E-2200 Processor Families with Intel(R) Processor Graphics may allow a privileged user to potentially enable information disclosure via local access.
