DescriptionCVE.org

Memory Corruption when user space address is modified and passed to mem_free API, causing kernel memory to be freed inadvertently.

Executive ViewAI

Why It Matters

CVE-2025-47358 is a kernel memory corruption vulnerability that could allow attackers to crash systems or potentially execute arbitrary code with elevated privileges. Without an available patch, organizations must immediately implement workarounds to reduce exposure while waiting for vendor remediation.

Business Impact: High

Compensating Controls

Restrict user-space access through privilege boundaries and SELinux/AppArmor policies; disable affected kernel subsystems or features if operationally feasible; implement network segmentation to limit lateral movement post-compromise; monitor system logs for kernel panics and memory corruption indicators; apply strict input validation at application layer; consider temporary migration of critical workloads to patched systems or alternative platforms; maintain enhanced logging of all user-space to kernel interface calls.
