HID: elan: Fix potential double free in elan_input_configured

2022-06-14T16:11:33Z

[ Upstream commit 1af20714fedad238362571620be0bd690ded05b6 ] 'input' is a managed resource allocated with devm_input_allocate_device(), so there is no need to call input_free_device() explicitly or there will be a double free. According to the doc of devm_input_allocate_device(): * Managed input devices do not need to be explicitly unregistered or * freed as it will be done automatically when owner device unbinds from * its driver (or binding fails).

HID: bigben: fix slab-out-of-bounds Write in bigben_probe

2022-06-14T16:11:27Z

[ Upstream commit fc4ef9d5724973193bfa5ebed181dba6de3a56db ] There is a slab-out-of-bounds Write bug in hid-bigbenff driver. The problem is the driver assumes the device must have an input but some malicious devices violate this assumption. Fix this by checking hid_device's input is non-empty before its usage.

HID: i2c-hid: fix GET/SET_REPORT for unnumbered reports

2022-04-15T12:18:12Z

[ Upstream commit a5e5e03e94764148a01757b2fa4737d3445c13a6 ] Internally kernel prepends all report buffers, for both numbered and unnumbered reports, with report ID, therefore to properly handle unnumbered reports we should prepend it ourselves. For the same reason we should skip the first byte of the buffer when calling i2c_hid_set_or_send_report() which then will take care of properly formatting the transfer buffer based on its separate report ID argument along with report payload.

HID: intel-ish-hid: Use dma_alloc_coherent for firmware update

2022-04-15T12:17:58Z

commit f97ec5d75e9261a5da78dc28a8955b7cc0c4468b upstream. Allocating memory with kmalloc and GPF_DMA32 is not allowed, the allocator will ignore the attribute. Instead, use dma_alloc_coherent() API as we allocate a small amount of memory to transfer firmware fragment to the ISH. On Arcada chromebook, after the patch the warning: "Unexpected gfp: 0x4 (GFP_DMA32). Fixing up to gfp: 0xcc0 (GFP_KERNEL). Fix your code!" is gone. The ISH firmware is loaded properly and we can interact with the ISH: > ectool --name cros_ish version ...
