CVE-2023-52494

CVE-2023-52494 concerns the Linux kernel bus: mhi driver. The vulnerability arises from an unaligned event ring read pointer reading 128-bit elements (struct mhi_ring_element). Although the code validates the pointer is within the buffer, an unaligned pointer could lead to DoS or ring-buffer memo...
