linux-toradex.git/drivers/hid/hid-vivaldi-common.c, branch v7.2-rc5 Linux kernel for Apalis and Colibri modules HID: pass the buffer size to hid_report_raw_event 2026-05-12T16:03:37+00:00 Benjamin Tissoires bentiss@kernel.org 2026-05-04T08:47:22+00:00 2c85c61d1332e1e16f020d76951baf167dcb6f7a commit 0a3fe972a7cb ("HID: core: Mitigate potential OOB by removing bogus memset()") enforced the provided data to be at least the size of the declared buffer in the report descriptor to prevent a buffer overflow. However, we can try to be smarter by providing both the buffer size and the data size, meaning that hid_report_raw_event() can make better decision whether we should plaining reject the buffer (buffer overflow attempt) or if we can safely memset it to 0 and pass it to the rest of the stack.
