GHSA-G2MQ-V2G4-XGCX

Vulnerability from github – Published: 2024-08-17 09:30 – Updated: 2025-10-02 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

spi: microchip-core: ensure TX and RX FIFOs are empty at start of a transfer

While transmitting with rx_len == 0, the RX FIFO is not going to be emptied in the interrupt handler. A subsequent transfer could then read crap from the previous transfer out of the RX FIFO into the start RX buffer. The core provides a register that will empty the RX and TX FIFOs, so do that before each transfer.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
