Worked on the google/security-research repository to deliver a consolidated mitigation for CVE-2025-38500 affecting the Linux kernel xfrm interface. Developed mitigation logic in C to address a use-after-free vulnerability in xfrmi_changelink, and provided detailed exploit documentation to support reproducibility and auditability. The work included a targeted fix in the exploit code, correcting ROP chain values and updating KASLR leak metadata to strengthen kernel defenses. Demonstrated expertise in kernel development, exploit development, and security research, while coordinating changes across multiple commits to ensure effective vulnerability remediation and improved security posture for Linux kernel deployments relying on xfrm.
