EUVD-2026-89172

Improper validation of non-secure NS pointers in multiple TrustZone-M non-secure callable NSC entry functions allows an attacker executing in the non-secure world to supply pointers to secure memory. The secure firmware subsequently dereferences these attacker-controlled pointers without verifyin...

CVE-2026-102709

An improper validation of non-secure (NS) pointers in multiple TrustZone-M non-secure callable (NSC) entry functions allows an attacker in the non-secure world to provide pointers to secure memory. The secure firmware fails to verify these pointers before dereferencing them, leading to unintended...

CVE-2026-77235: Use After Free

Missing privilege verification in the secure context cleanup handler in FreeRTOS-Kernel before 11.3.1 might allow local users to cause a use-after-free condition in secure-world memory via the SVC handler for secure context deallocation. To remediate this issue, users should upgrade to...

CVE-2026-77236: Out-of-bounds Write

Missing minimum size validation in secure context allocation in FreeRTOS-Kernel before 11.3.1 might allow local users to corrupt secure-world heap metadata via an out-of-bounds write with an undersized stack size parameter. To remediate this issue, users should upgrade to version 11.3.1 or later...
