CVE-2023-50096
Last modified
CVE-2023-50096 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. STMicroelectronics STSAFE-A1xx middleware before 3.3.7 allows MCU code execution if an adversary has the ability to read from and write to the I2C bus. This is caused by an StSafeA_ReceiveBytes buffer overflow in the X-CUBE-SAFEA1 Software Package for STSAFE-A sample applications (1.2.0), and thus can affect user-written code that was derived from a published sample application.. EPSS estimates a 0.60% chance of exploitation in the next 30 days.
