Overview

CVE-2026-23202 is a medium-severity vulnerability. It was published on February 14, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
