Short explanation
Improper input validation in the NXP MCUXpresso SDK rpmsg-lite TZM example allows a non-secure caller to supply unvalidated pointers and size values [S0]. This may result in the disclosure of secure-world memory to the non-secure domain or a denial of service [S0].
It enables an unauthorized caller to access sensitive memory regions, leading to confidentiality breaches and service disruptions [S0].
What should be done?
- Follow vendor advisories [S0]

Show the technical text from the sources
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.
