O implementare a protocolului SCTP, propus\u0103 \u00een nucleul Linux, a dezv\u0103luit o vulnerabilitate (CVE-2026-64564) care permite unui utilizator local s\u0103 ob\u021bin\u0103 privilegii de root \u00een sistem. Printre altele, vulnerabilitatea permite ob\u021binerea accesului root \u00een sistemul principal prin rularea unui exploit \u00eentr-un container izolat. A fost preg\u0103tit un prototip al exploit-ului, a c\u0103rui func\u021bionare a fost demonstrat\u0103 \u00een distribu\u021bii precum Debian 13, Rocky Linux 9, RHEL 9 \u0219i Ubuntu 24.04 cu nucleele 5.14, 6.6, 6.8 \u0219i 6.12. <\/p>\n

Vulnerabilitatea este cauzat\u0103 de accesarea memoriei deja eliberate \u00een codul de reconstruc\u021bie dinamic\u0103 a adreselor SCTP (ASCONF). nucleul p\u0103streaz\u0103 un pointer c\u0103tre transport (asconf->transport), specificat \u00een pachet, dar memoria asociat\u0103 cu acest pointer poate fi cur\u0103\u021bat\u0103, de\u0219i pointerul \u00een sine c\u0103tre memoria deja eliberat\u0103 va continua s\u0103 fie utilizat \u00een procesarea altor comenzi. Atacul se realizeaz\u0103 prin trimiterea c\u0103tre un socket local a unei secven\u021be specifice de comenzi ASCONF pentru reconfigurarea adresei: mai \u00eent\u00e2i se trimite un pachet DEL-IP pentru a elimina transportul pentru un IP specific, urmat de un pachet DEL-IP cu masca 0.0.0.0, procesarea c\u0103ruia va duce la reutilizarea pointerului r\u0103mas. <\/p>\n

Vulnerabilitatea este cauzat\u0103 de o eroare comis\u0103 acum 18 ani \u00een nucleul 2.6.25 (2008) \u0219i corectat\u0103 \u00een versiunile 6.6.148, 6.12.101, 6.18.42, 7.1.6 \u0219i 7.2-rc5. Starea remedierii vulnerabilit\u0103\u021bilor \u00een distribu\u021bii poate fi evaluat\u0103 pe aceste pagini: Debian, Ubuntu, SUSE\/openSUSE, RHEL, Gentoo, Arch, Fedora.
