A SCTP protocol vulnerability, proposed in the Linux kernel, has been identified (CVE-2026-64564) that allows a local user to gain root privileges in the system. Among other things, the vulnerability allows root access to the main system when the exploit is run in an isolated container. A prototype of the exploit has been prepared and demonstrated in the Debian 13, Rocky Linux 9, RHEL 9, and Ubuntu 24.04 distributions with kernels 5.14, 6.6, 6.8, and 6.12. <\/p>\n

A sebezhet\u0151s\u00e9g az SCTP (ASCONF) c\u00edmek dinamikus \u00fajrakonfigur\u00e1ci\u00f3s k\u00f3dj\u00e1ban m\u00e1r felszabad\u00edtott mem\u00f3ria el\u00e9r\u00e9s\u00e9b\u0151l ad\u00f3dik.

The vulnerability is due to a mistake made 18 years ago in kernel 2.6.25 (2008) and fixed in the releases 6.6.148, 6.12.101, 6.18.42, 7.1.6, and 7.2-rc5. The status of vulnerabilities fix in the distributions can be assessed on the following pages: Debian, Ubuntu, SUSE\/openSUSE, RHEL, Gentoo, Arch, Fedora.
