What it actually does

The flaw permits a shift-out-of-bounds operation inside snto32() when hid_report_raw_event receives an HID report field size n exceeding 32 bits, causing an invalid shift exponent on a 32-bit integer and triggering UBSAN-detected undefined behavior.

Why it matters to the business

Systems running affected kernels may experience crashes or instability when processing input from certain USB HID devices, leading to operational disruption; however, low EPSS and absence from KEV indicate limited real-world risk and reduced urgency for immediate action.

How an attack unfolds

An attacker supplies a crafted HID report (via malicious USB device) containing a field size greater than 32 bits; during kernel processing the oversized value reaches snto32() inside hid_report_raw_event, producing the out-of-bounds shift.

How to fix it

Update the Linux kernel to a version containing commit 151493fe5a6ed1a88decc929a7368a3f2a246914 (or later equivalent) in the stable tree; rebuild and reboot with the patched kernel.

How to confirm the fix worked

Verify the running kernel source contains the snto32 bounds check added in commit 151493fe5a6ed1a88decc929a7368a3f2a246914 and confirm absence of UBSAN shift-out-of-bounds warnings during HID report processing.

Typical attack path

  1. Attach malicious USB HID device to target system
  2. Kernel receives and parses HID input report
  3. hid_report_raw_event invokes hid_input_fetch_field and snto32 with n > 32
  4. Shift exponent exceeds 32-bit width, triggering undefined behavior or crash

How to detect it

Search kernel logs and dmesg for UBSAN messages referencing hid-core.c shift-out-of-bounds or hid_report_raw_event; correlate with USB device attach events from untrusted sources.

What your security team should do

  • Apply the referenced kernel commit or distribution update as soon as practical
  • Restrict untrusted USB HID devices on high-value systems until patched
  • Monitor kernel logs for hid-core UBSAN reports as an interim detection measure

Fix this by adding a check on the size of the integer (unsigned n) in snto32(). To add support for n greater than 32 bits, set n to 32, if n is greater than 32.
