Debian Bug : 1095805

Microcode updates has been released for Intel(R) processors, addressing
multiple potential vulnerabilties that may allow local privilege escalation,
denial of service or information disclosure.

CVE-2023-34440 (INTEL-SA-01139)

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

CVE-2023-43758 (INTEL-SA-01139)

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

CVE-2024-24582 (INTEL-SA-01139)

Improper input validation in XmlCli feature for UEFI firmware for some
Intel(R) processors may allow privileged user to potentially enable
escalation of privilege via local access.

CVE-2024-28047 (INTEL-SA-01139)

Improper input validation in UEFI firmware for some Intel(R) Processors
may allow a privileged user to potentially enable information disclosure
via local access.

CVE-2024-28127 (INTEL-SA-01139)

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

CVE-2024-29214 (INTEL-SA-01139)

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

CVE-2024-31068 (INTEL-SA-01166)

Improper Finite State Machines (FSMs) in Hardware Logic for some
Intel(R) Processors may allow privileged user to potentially enable
denial of service via local access.

CVE-2024-31157 (INTEL-SA-01139)

Improper initialization in UEFI firmware OutOfBandXML module in some
Intel(R) Processors may allow a privileged user to potentially enable
information disclosure via local access.

CVE-2024-36293 (INTEL-SA-01213)

Improper access control in the EDECCSSA user leaf function for some
Intel(R) Processors with Intel(R) SGX may allow an authenticated user to
potentially enable denial of service via local access.

CVE-2024-37020 (INTEL-SA-01194)

Sequence of processor instructions leads to unexpected behavior in the
Intel(R) DSA V1.0 for some Intel(R) Xeon(R) Processors may allow an
authenticated user to potentially enable denial of service via local
access.

CVE-2024-39279 (INTEL-SA-01139)

Insufficient granularity of access control in UEFI firmware in some
Intel(R) processors may allow a authenticated user to potentially enable
denial of service via local access.

CVE-2024-39355 (INTEL-SA-01228)

Improper handling of physical or environmental conditions in some
Intel(R) Processors may allow an authenticated user to enable denial of
service via local access.

For Debian 11 bullseye, these problems have been fixed in version
3.20250211.1~deb11u1.
