Input: gpio-keys - fix possible concurrent access in gpio_keys_irq_timer()

2025-06-27T10:11:20+00:00

commit 8f38219fa139623c29db2cb0f17d0a197a86e344 upstream. gpio_keys_irq_isr() and gpio_keys_irq_timer() access the same resources. There could be a concurrent access if a GPIO interrupt occurs in parallel of a HR timer interrupt. Guard back those resources with a spinlock.

Input: ims-pcu - check record size in ims_pcu_flash_firmware()

2025-06-27T10:11:20+00:00

commit a95ef0199e80f3384eb992889322957d26c00102 upstream. The "len" variable comes from the firmware and we generally do trust firmware, but it's always better to double check. If the "len" is too large it could result in memory corruption when we do "memcpy(fragment->data, rec->data, len);" Fixes: 628329d52474 ("Input: add IMS Passenger Control Unit driver") Signed-off-by: Dan Carpenter Link: https://lore.kernel.org/r/131fd1ae92c828ee9f4fa2de03d8c210ae1f3524.1748463049.git.dan.carpenter@linaro.org Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: synaptics-rmi - fix crash with unsupported versions of F34

2025-06-19T13:32:22+00:00

[ Upstream commit ca39500f6af9cfe6823dc5aa8fbaed788d6e35b2 ] Sysfs interface for updating firmware for RMI devices is available even when F34 probe fails. The code checks for presence of F34 "container" pointer and then tries to use the function data attached to the sub-device. F34 assigns the function data early, before it knows if probe will succeed, leaving behind a stale pointer. Fix this by expanding checks to not only test for presence of F34 "container" but also check if there is driver data assigned to the sub-device, and call dev_set_drvdata() only after we are certain that probe is successful. This is not a complete fix, since F34 will be freed during firmware update, so there is still a race when fetching and accessing this pointer. This race will be addressed in follow-up changes.
