What to do
AI-suggested
A fix has been implemented in the Linux kernel by dropping the legacy remove function and using devm_add_action_or_reset() for cleanup. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's fsl-qspi SPI driver could cause a kernel panic during device detach on i.MX8MQ platforms. The issue arises because the driver uses legacy remove functions that are called before devm-managed resources are released, leading to improper cleanup and system instability. The fix involves removing the legacy remove function and using devm_add_action_or_reset() to ensure proper release sequencing.
