CVE-2026-118786
NXP MCUXpresso SDK rpmsg-lite TZM Example before 26.06.01-lts Secure Memory Disclosure via NSC Veneer Functions
Improper input validation in non-secure-callable (NSC) veneer functions of the NXP MCUXpresso SDK rpmsg-lite multicore example (multicore_examples/rpmsg_lite_pingpong_tzm) up to releases 26.06.00-lts and 26.09.00 may allow a non-secure caller to supply unvalidated pointers and size values, potentially resulting in disclosure of secure-world memory to the non-secure domain, or denial of service. All software versions starting from 26.06.01-lts and 26.12.00-pvw1 have fixed this issue.
