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

HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq

The wacom_intuos_bt_irq() function processes Bluetooth HID reports

without sufficient bounds checking. A maliciously crafted short report

can trigger an out-of-bounds read when copying data into the wacom

structure.

Specifically, report 0x03 requires at least 22 bytes to safely read

the processed data and battery status, while report 0x04 (which

falls through to 0x03) requires 32 bytes.

Add explicit length checks for these report IDs and log a warning if

a short report is received. (NVD)
