  "details": "In the Linux kernel, the following vulnerability has been resolved:  misc: fastrpc: possible double-free of cctx-\u003eremote_heap  fastrpc_init_create_static_process() may free cctx-\u003eremote_heap on the err_map path but does not clear the pointer. Later, fastrpc_rpmsg_remove() frees cctx-\u003eremote_heap again if it is non-NULL, which can lead to a double-free if the INIT_CREATE_STATIC ioctl hits the error path and the rpmsg device is subsequently removed/unbound. Clear cctx-\u003eremote_heap after freeing it in the error path to prevent the later cleanup from freeing it again.  This issue was found by an in-house analysis workflow that extracts AST-based information and runs static checks, with LLM assistance for triage, and was confirmed by manual code review. No hardware testing was performed.",
