In ONNX before 1.21.0, the 'save_external_data' function builds the external-data file path from the model's external_data location field and opens it for writing without 'O_NOFOLLOW/O_EXCL', after a non-atomic 'os.path.isfile()' check. A local attacker with write access to the directory where a victim serializes external data can deterministically pre-plant a symlink that is being followed, causi…

Secure BootROM of RK3588s SoC is vulnerable to a time-of-check to time-of-use attack in case of booting from external media (SPI NOR or NAND, EMMC or SD). The code reads the header of the next-stage loader twice. The header contains hashes of the executable modules and is signed with a private key, the public part of which is verified against the SHA256 digest blown in the OTP. The first r…

Budibase is an open-source low-code platform. Prior to 3.40.0, packages/backend-core/src/utils/outboundFetch.ts pinned a validated address through a Node agent, but the REST integration used getDispatcher from packages/backend-core/src/utils/fetch.ts, causing undici to ignore that agent and resolve the hostname again. A builder could use DNS rebinding to make packages/server/src/integrations/rest.…

An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD performs restriction checks before configuration merging is complete, creating a time-of-check to time-of-use (TOCTOU) condition. An attacker can …

Vulnerabilidad alta en verificadores de syscall de Zephyr RTOS permite escalada de privilegios

Los verificadores de syscall z_vrfy_zsock_sendmsg() y z_vrfy_zsock_recvmsg() en Zephyr RTOS contienen un defecto de validación donde se captura una copia de estructuras de usuario pero se vuelve a leer la estructura original en vivo para decisiones posteriores. Esto permite a atacantes locales modificar buffers iovec entre verificación y uso, escalando privilegios en sistemas embebidos y IoT. Afecta principalmente a dispositivos industrial IoT, telecomunicaciones y sistemas altas en operación en LATAM.
