Description
A race condition was found in the Tegra210 Quad SPI driver's IRQ handler. The curr_xfer pointer is checked for NULL without holding the spinlock, but can be set to NULL by the timeout path between the check and subsequent use, leading to a NULL pointer dereference when accessing t->len.
Statement
This vulnerability affects NVIDIA Tegra210-based systems using the Quad SPI controller. The race requires precise timing between the ISR thread and timeout handling, making it difficult to trigger but causing a kernel crash when it occurs.
