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

The vulnerability is caused by accessing already freed memory in the code for dynamic SCTP address reconfiguration (ASCONF). The kernel caches a pointer to the transport (asconf->transport) indicated in the packet, but the memory associated with this pointer can be freed, while the pointer to this already freed memory continues to be used in processing other commands. The attack is carried out by sending a specific sequence of ASCONF reconfiguration commands to the local socket: first, a DEL-IP packet is sent to remove the transport for a specific IP, followed by a DEL-IP packet indicating the mask 0.0.0.0, the processing of which will lead to the reuse of the remaining dangling pointer. <\/p>\n

The vulnerability stems from an error made 18 years ago in kernel 2.6.25 (2008) and was fixed in releases 6.6.148, 6.12.101, 6.18.42, 7.1.6, and 7.2-rc5. The status of vulnerability remediation in the distributions can be assessed on these pages: Debian, Ubuntu, SUSE\/openSUSE, RHEL, Gentoo, Arch, Fedora.
