  "details": "In the Linux kernel, the following vulnerability has been resolved:  procfs: fix possible double mmput() in do_procmap_query()  When user provides incorrectly sized buffer for build ID for PROCMAP_QUERY we return with -ENAMETOOLONG error.  After recent changes this condition happens later, after we unlocked mmap_lock/per-VMA lock and did mmput(), so original goto out is now wrong and will double-mmput() mm_struct.  Fix by jumping further to clean up only vm_file and name_buf.",
