GHSA-JVRG-CVPM-4P85

Vulnerability from github – Published: 2024-08-07 18:30 – Updated: 2024-08-08 21:32

Details

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

spi: don't unoptimize message in spi_async()

Calling spi_maybe_unoptimize_message() in spi_async() is wrong because the message is likely to be in the queue and not transferred yet. This can corrupt the message while it is being used by the controller driver.

spi_maybe_unoptimize_message() is already called in the correct place in spi_finalize_current_message() to balance the call to spi_maybe_optimize_message() in spi_async().

Severity ?

3.3 (Low)
