"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncdx: Fix double free when sysfs file creation fails\n\nIn cdx_create_res_attr(), if sysfs_create_bin_file() fails, the code\nfrees res_attr but doesn't set cdx_dev->res_attr[num] to NULL. 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."
