CVE-2026-118785

NXP MCUXpresso SDK TrustZone-M Examples before 26.06.01-lts Secure Memory Disclosure via NSC Veneer Functions

Assigner: ENISA
Reserved: 28.10.2026 Published: 06.11.2026 Updated: 06.11.2026

Improper handling of non-secure-world input in NSC veneer functions of NXP MCUXpresso SDK TrustZone-M examples (trustzone_examples), affecting versions through 26.06.00-lts and 26.09.00-pvw2, may allow a non-secure caller to supply unvalidated pointers or untrusted data, causing a timing side-channel, TOCTOU condition, or format-string misuse, potentially resulting in secure-world memory disclosure or denial of service. All software versions starting from 26.06.01-lts and 26.09.00 have fixed this issue.
