UEFI Firmware Parser parses BIOS, Intel ME, and UEFI firmware structures including volumes, file systems, and files. Prior to 1.14, ReadCLen() in uefi_firmware/compression/Tiano/Decompress.c reads Number from GetBits(Sd, CBIT) with CBIT = 9 and can obtain 511 entries for the 510-element Sd->mCLen heap array because…

UEFI Firmware Parser parses BIOS, Intel ME, and UEFI firmware structures including volumes, file systems, and files. Prior to 1.14, MakeTable() in uefi_firmware/compression/Tiano/Decompress.c does not validate that bit-length values read from a crafted Tiano or EFI compressed firmware bitstream remain within the…

Incomplete cleanup in some UEFI firmware for some Intel(R) reference platforms within UEFI may allow an information disclosure. System software adversary with a privileged user combined with a low complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements…

Improper buffer restrictions in some UEFI firmware for some Intel(R) reference platforms may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable data manipulation. This result may potentially occur via local access when attack…

Clevo’s UEFI firmware update packages, including B10717.exe, inadvertently contained private signing keys used for Boot Guard and Boot Policy Manifest verification. The exposure of these keys could allow attackers to sign malicious firmware that appears trusted by affected systems, undermining the integrity of the…

An arbitrary write vulnerability in Microsoft signed UEFI firmware allows for code execution of untrusted software. This allows an attacker to control its value, leading to arbitrary memory writes, including modification of critical firmware settings stored in NVRAM. Exploiting this vulnerability could enable security…
