CVE-2026-68400

CVE-2026-68400 concerns the Linux kernel firmware/arm_ffa component. The issue arises from an incorrect calculation of the Endpoint Memory Access Descriptor offset, where the code defaulted to the size of the ffa_mem_region instead of using the descriptor’s ep_mem_offset. The patch relocates ffa_...
