EUVD-2026-67962

IGEL OS 12 before 12.9.0, 12.8.3 LTS and IGEL OS 11 before 11.11.150 contain a secure boot bypass vulnerability in the GRUB boot stage that allows physically present attackers to gain unauthorized root access by placing an unsigned empty file named igel.conf on a partition. Attackers can exploit...

CVE-2026-82018

IGEL OS 12 (before 12.9.0 / 12.8.3 LTS ) and IGEL OS 11 (before 11.11.150 ) contain a secure boot bypass in the GRUB boot stage .

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module that serves as a dependency without checking whether any other dependent modules are still loaded, leading to a “use-after-free” scenario. This could allow arbitrary code to be...

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 edk2

In Ubuntu’s EDK2, a insecure default setting was left enabled, allowing UEFI Shell to be used. This enables an attacker with access to the operating system to bypass Secure Boot...

CVE-2026-50719

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

The Ingenic T41 SoC boot ROM (and likely T32, T40, and A1 ) parses and executes an attacker-controlled init table from the SPL header before performing any secure boot state check or signature verification. Because the init table parser supports full-address 32-bit write operations , an attacker ...

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. 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...
