EUVD-2026-62479
The Ingenic T41, and probably also T32, T40, and A1 SoC boot ROMs parse and execute an attacker-controlled init table from the SPL header before checking the secure boot state and before invoking signature verification. The init table parser supports full-address 32-bit write operations, allowing...
EUVD-2026-62480
The Ingenic T31 SoC boot ROM flash-boot verification path compares only a single 32-bit word of the RSA signature output against a single 32-bit word of the SHA-256 payload digest, rather than compare the full data. This allows an attacker with physical write access to boot media to forge modifie...
CVE-2026-50719
Ingenic T41/T32/T40/A1 SoC boot ROMs execute an attacker-controlled init table from the SPL header before secure boot verification, using 32-bit writes to disable SRAM-resident secure boot state, allowing unsigned boot code. Hardware-validated on T41; ROM analysis confirms behavior on other chips...
CVE-2025-59327
In CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4, bootxsa.efi fails to properly validate LUKS encryption and, if encryption is present, all CryptoPro file integrity checks are skipped...
Astra Linux – Vulnerability in grub2
A flaw was discovered in grub2. When reading the name of a symbolic link from a UFS filesystem, grub2 fails to validate the string length provided as input. This lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and potentially allowing an attacker to...
Astra Linux – Vulnerability in grub2
A flaw was discovered in grub2. A specially crafted JPEG file can cause the JPEG parser in grub2 to incorrectly check the boundaries of its internal buffers, leading to an out-of-bounds write. The possibility of overwriting sensitive information to bypass secure boot protections is still a concer...
Astra Linux – Vulnerability in grub2
A flaw was discovered in grub2. The calculation of the translation buffer when reading a language .mo file in grubgettextgetstrfromposition may overflow, resulting in an out-of-bound write. This issue can be exploited by an attacker to overwrite grub2’s sensitive heap data, ultimately allowing th...
CVE-2026-11835
Time-of-check time-of-use TOCTOU vulnerability combined with missing input validation in Caliptra Core ROM UpdateResetFlow::run in subsystem mode allows a compromised local attacker to silently bypass secure boot by supplying an AXI staging address that is not validated against the strap-configur...

CVE-2026-11835
Caliptra Core ROM (2.1.0–2.1.1) contains a TOCTOU vulnerability in UpdateResetFlow::run() that, with missing input validation, lets a compromised MCU firmware with AXI manager access inject an unvalidated AXI staging address. This bypasses secure boot by not validating against SS_EXTERNAL_STAGING...
