DEBIAN-CVE-2026-23178
In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report() `i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data into `ihid->rawbuf`. The former can come from the userspace in the hidraw driver and is only bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set `max_buffer_size` field of `struct hid_ll_driver` which we do not). The latter has size determined at runtime by the maximum size of different report types you could receive on any particular device and can be a much smaller value. Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`. The impact is low since access to hidraw devices requires root.
