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

HID: nintendo: fix out-of-bounds read in joycon_ctlr_read_handler()

joycon_ctlr_read_handler() casts an incoming HID input report to struct joycon_input_report and parses it, guarding the cast only with a 12-byte length check:

if (size >= 12) /* make sure it contains the input report */ joycon_parse_report(ctlr, (struct joycon_input_report *)data);

struct joycon_input_report is 49 bytes: a 13-byte header followed by a union whose IMU arm is 36 bytes. For an IMU report joycon_parse_report() -> joycon_parse_imu_report() walks that union (struct offsets 13..48), so a report of exactly 12 bytes with data[0] == JC_INPUT_IMU_DATA passes the guard yet is read up to 37 bytes past its declared length. The over-read bytes are decoded into accelerometer/gyroscope values and forwarded to userspace through the "(IMU)" input device, leaking driver-internal memory. data[0] and size are fully controlled by a malicious or spoofed Joy-Con/Pro Controller.

Receive buffers are sized to the maximum report length, so this is an over-read within the allocation rather than a slab OOB, but the decoded bytes still reach userspace.

The sibling subcmd path in joycon_ctlr_handle_event() already bounds the same cast correctly:

if (size < sizeof(struct joycon_input_report) || data[0] != JC_INPUT_SUBCMD_REPLY) break;

Use the same sizeof(struct joycon_input_report) bound here.

WID-SEC-W-2026-3211 — Linux Kernel: Mehrere Schwachstellen

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Linux Kernel ausnutzen, um Speicherfehler und Kernel-Abstürze beziehungsweise Denial-of-Service-Zustände auszulösen, Speicher außerhalb vorgesehener Grenzen auszulesen sowie in einzelnen Fällen weitere Sicherheitsauswirkungen zu verursachen.
