Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
spi: tegra210-quad: Protect curr_xfer in tegra_qspi_combined_seq_xfer<br />
<br />
The curr_xfer field is read by the IRQ handler without holding the lock<br />
to check if a transfer is in progress. When clearing curr_xfer in the<br />
combined sequence transfer loop, protect it with the spinlock to prevent<br />
a race with the interrupt handler.<br />
<br />
Protect the curr_xfer clearing at the exit path of<br />
tegra_qspi_combined_seq_xfer() with the spinlock to prevent a race<br />
with the interrupt handler that reads this field.<br />
<br />
Without this protection, the IRQ handler could read a partially updated<br />
curr_xfer value, leading to NULL pointer dereference or use-after-free.
