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.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
