CVE-2026-23207

CVE-2026-23207 concerns the Linux kernel SPI Tegra210 quad driver. The issue arose because curr_xfer accesses were not consistently protected by the lock in the IRQ thread path, enabling a race against the timeout path where curr_xfer could be NULL after being cleared but still dereferenced in ha...
