CVE-2026-23202

System crash via unlocked QSPI transfer pointer

Published Feb 14, 2026 · Updated Feb 14, 2026

Race condition in the Tegra210 QSPI driver in Linux Kernel allows local users to crash the system during combined-sequence transfers. The tegra_qspi_combined_seq_xfer() exit path clears curr_xfer without the spinlock while the IRQ handler reads it, exposing a partial pointer and causing a NULL dereference or use-after-free. Triggering requires a system using the Tegra210 QSPI driver and a concurrent interrupt during transfer cleanup; the documented consequence is a kernel crash, not code execution.
