CVSS 3.1
7.5 highCVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2023-50096
High (7.5) in st x-cube-safea1. EPSS 0.6% chance of exploitation in the next 30 days.
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.
