Research

We discovered a use-after-free vulnerability in the core of the TCP subsystem of the Linux kernel (CVE-2024-36904).

We reported a nday vulnerability (CVE-2023-52922) affecting Red Hat Enterprise Linux 9 and its derivatives. The exploitation of the vulnerability allows the leaking of the encoded freelist pointer and the addresses of the slab.

We discovered two vulnerabilities in the CAN BCM subsystem. A use-after-free affecting the proc entry and an out-of-bounds read. CVE-2025-38003 and CVE-2025-38004.
