CVE-2026-93215: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: cdx: Fix double free when sysfs file creation fails In cdx_create_res_attr(), if sysfs_create_bin_file() fails, the code frees res_attr but doesn't set cdx_dev->res_attr[num] to NULL. This leaves a dangling pointer in the array. Then cdx_destroy_res_attr() frees the already-freed memory. Fix the double free by initializing cdx_dev->res_attr[num] after sysfs_create_bin_file() completes.
