Summary
spi: tegra210-quad: Protect curr_xfer in tegra_qspi_combined_seq_xfer
Details

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

spi: tegra210-quad: Protect currxfer in tegraqspicombinedseq_xfer

The currxfer field is read by the IRQ handler without holding the lock to check if a transfer is in progress. When clearing currxfer in the combined sequence transfer loop, protect it with the spinlock to prevent a race with the interrupt handler.

Protect the currxfer clearing at the exit path of tegraqspicombinedseq_xfer() with the spinlock to prevent a race with the interrupt handler that reads this field.

Without this protection, the IRQ handler could read a partially updated curr_xfer value, leading to NULL pointer dereference or use-after-free.
