In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability in base64 PEM file decoding allows system-level (administrator) attackers to obtain information about secret RSA keys via a controlled-channel and side-channel attack on software running in isolated environments that can be single stepped, especially Intel SGX. En Trusted Firmware Mbed versión TLS versión 2.24.0, una vulnerabilidad de canal lateral en la decodificación de archivos PEM base64, permite a atacantes a nivel de sistema (administrador) obtener información sobre claves RSA secretas por medio de un ataque de canal controlado y de canal lateral en el software ejecutándose entornos aislados que pueden ser de un solo paso, especialmente Intel SGX • https://github.com/ARMmbed/mbedtls/releases https://github.com/UzL-ITS/util-lookup/blob/main/cve-vulnerability-publication.md https://lists.debian.org/debian-lts-announce/2021/11/msg00021.html https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DRRVY7DMTX3ECFNZKDYTSFEG5AI2HBC6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EYJW7HAW3TDV2YMDFYXP3HD6WRQRTLJW • CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2021-29256
. The Arm Mali GPU kernel driver allows an unprivileged user to achieve access to freed memory, leading to information disclosure or root privilege escalation. This affects Bifrost r16p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r28p0 through r30p0. El controlador del kernel de la GPU Arm Mali, permite a un usuario no privilegiado acceder a la memoria liberada, conllevando a una divulgación de información o una escalada de privilegios de root. Esto afecta a Bifrost versiones r16p0 hasta r29p0 anteriores a r30p0, Valhall r19p0 hasta r29p0 anteriores a r30p0 y Midgard versiones r28p0 hasta r30p0 Arm Mali GPU Kernel Driver contains a use-after-free vulnerability that may allow a non-privileged user to gain root privilege and/or disclose information. • https://developer.arm.com/support/arm-security-updates/mali-gpu-kernel-driver • CWE-416: Use After Free •
