From STM32F4xx Standard Peripherals Drivers V1.8.1 (27-January-2022) release notes:

stm32f4xx_can.c:

  • Update to avoid race condition
    • Update CAN_Receive(), CAN_FIFORelease() & CAN_CancelTransmit() APIs to use '=' instead of '|='.

Analyzing the current code of the file stm32f4xx_hal_can.c you can still see the use of SET_BIT().
Is this race condition not present in the HAL driver and/or has it been resolved elsewhere?
