Technical details
This is an out-of-bounds read vulnerability in the Windows NTFS file system driver. The vulnerability allows an authenticated local attacker to read memory contents beyond intended buffer boundaries, potentially disclosing sensitive information from kernel memory or other protected regions. The attack requires local system access and does not involve network-based exploitation. Microsoft has addressed this issue through a security update that bounds the memory access properly.
