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)
