CVE-2025-23142 is a use-after-free vulnerability in the Linux kernel's SCTP implementation, affecting Debian and other Linux distributions. It arises from a race condition during sctp_sendmsg() where a transport can be freed while a message is being prepared, leading to a use-after-free read. Rated 7.8 HIGH (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), this local vulnerability has high impacts on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
