Description

In the Linux kernel, the following vulnerability has been resolved: spi: tegra210-quad: Protect curr_xfer in tegra_qspi_combined_seq_xfer The curr_xfer field is read by the IRQ handler without holding the lock to check if a transfer is in progress. When clearing curr_xfer in the combined sequence transfer loop, protect it with the spinlock to prevent a race with the interrupt handler. Protect the curr_xfer clearing at the exit path of tegra_qspi_combined_seq_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.

Affected configurations

• linux linux kernel (>= 5.15.198 < 5.15.200) • linux linux kernel (>= 6.1.160 < 6.1.163) • linux linux kernel (>= 6.6.120 < 6.6.124) • linux linux kernel (>= 6.12.63 < 6.12.70) • linux linux kernel (>= 6.17.13 < 6.18) • linux linux kernel (>= 6.18.2 < 6.18.10) • linux linux kernel 6.19
