This\nleaves a dangling pointer in the array. Then cdx_destroy_res_attr()\nfrees the already-freed memory. Fix the double free by initializing\ncdx_dev->res_attr[num] after sysfs_create_bin_file() completes.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/4cd24873ab9fdbd730604881a6e8087bc7b99336","tags":[]},{"url":"https://git.kernel.org/stable/c/6f4acc3a3c300e174e3f586b97b04ed8f5948c36","tags":[]},{"url":"https://git.kernel.org/stable/c/7e9451bf0bdba6daee1eaf4e7566612af6ca1c32","tags":[]},{"url":"https://git.kernel.org/stable/c/88f4cd42a04bdadd189d7f667a4c279f4e962ca6","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
