Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bus: mhi: ep: Update read pointer only after buffer is written<br /> <br /> Inside mhi_ep_ring_add_element, the read pointer (rd_offset) is updated<br /> before the buffer is written, potentially causing race conditions where<br /> the host sees an updated read pointer before the buffer is actually<br /> written. Updating rd_offset prematurely can lead to the host accessing<br /> an uninitialized or incomplete element, resulting in data corruption.<br /> <br /> Invoke the buffer write before updating rd_offset to ensure the element<br /> is fully written before signaling its availability.
