Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: synaptics-rmi4 - block s_input when F54 queue is busy<br /> <br /> Changing the input (diagnostic report type) mid-stream changes the<br /> report size. Since V4L2 buffers are allocated based on the size at<br /> stream start, changing the input while streaming could lead to a<br /> heap buffer overflow if the new size is larger than the allocated<br /> buffers.<br /> <br /> Prevent this by blocking VIDIOC_S_INPUT with -EBUSY if the V4L2 queue<br /> is busy (streaming).
