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. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It’s possible to cause the allocation length to overflow with a specially crafted tar file, resulti...

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...

CVE-2026-20466
CVE-2026-20466 : A heap buffer overflow in the secure boot flow may allow local privilege escalation with physical access and no user interaction. Affected platforms include MT2737 (AUTO00845351) and MT6880/MT6890/MT6990 (ALPS11072643); Issue MSV-6929. Patch guidance is provided in the MT securit...
EUVD-2026-52056
In sec boot, there is a possible escalation of privilege due to a heap buffer overflow. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID:...
