CVE-2026-31730

CVE-2026-31730 affects the Linux kernel fastrpc component, where a double-free of cctx->remote_heap could occur if INIT_CREATE_STATIC ioctl hits an error path and the rpmsg device is removed. The root cause is that fastrpc_init_create_static_process() frees cctx->remote_heap on the err_map ...
