  2. Vulnerabilities (CVE)
  3. CVE-2024-39499
In the Linux kernel, the following vulnerability has been resolved: vmci: prevent speculation leaks by sanitizing event in event_deliver() Coverity spotted that event_msg is controlled by user-space, event_msg->event_data.event is passed to event_deliver() and used as an index without sanitization. This change ensures that the event index is sanitized to mitigate any possibility of speculative information leaks. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc. Only compile tested, no access to HW.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: vmci: evita fugas especulativas sanitizando el evento en event_deliver(). Coverity detectó que event_msg está controlado por el espacio de usuario, event_msg->event_data.event se pasa a event_deliver() y se usa como un índice sin sanitización. Este cambio garantiza que el índice de eventos esté sanitizado para mitigar cualquier posibilidad de fuga de información especulativa. Este error fue descubierto y resuelto utilizando Coverity Static Analysis Security Testing (SAST) por Synopsys, Inc. Solo se prueba la compilación, no hay acceso al hardware.
