GHSA-9R4W-JG96-92MV Go-Attestation: Hash injection into trusted measurement list via unskipped SignatureHeaderSize vendor bytes in parseEfiSignatureList()

Summary parseEfiSignatureList in attest/internal/events.go does not skip SignatureHeaderSize vendor bytes before reading EFISIGNATURELIST signature entries, violating UEFI specification section 31.4.1. Impact For hashSHA256SigGUID lists, attacker-controlled vendor header bytes are appended direct...

Improper Validation of Specified Index, Position, or Offset in Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Index, Position, or Offset in Input in the parseEfiSignatureList process. An attacker can cause a remote attestation verifier to accept a compromised boot state as legitimate by injecting arbitrary SHA25...

VeraCrypt provides disk encryption with strong security based on TrueCrypt. Prior to 1.26.29, non-default builds created with WOLFCRYPT=1 and WOLFCRYPT BACKEND route SHA-256 and SHA-512 volume-header key derivation through derive key sha256 and derive key sha512 in src/Crypto/wolfCrypt.c, where t...

CVE-2026-46290

The CVE-2026-46290 issue in Linux kernels’ x86 EFI runtime handling was fixed by replacing in_interrupt() with !in_task() to preserve interrupt/NMI fault handling without being affected by the FPU softirq path. Root cause: kernel_fpu_begin() uses fpregs_lock() with local_bh_disable(), setting SOF...
