CVE-2026-64276

CVE-2026-64276 affects the Linux kernel synaptics-rmi4 input driver. The F30/GP I/O mapping code incorrectly allocated gpioled_key_map for at most 6 entries but later iterated up to gpioled_count (0..31) and advanced input->keycodemax to the full count, risking out-of-bounds reads in the atten...

kernel: Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()

In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - fix use after free in rmiunregisterfunction The putdevice calls rmireleasefunction which frees "fn" so the dereference on the next line "fn-numofirqs" is a use after free. Move the putdevice to the end to...
