Описание
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.
A vulnerability was found in the event_deliver() function in the Linux kernel's VMCI component, where the issue involves a lack of sanitization for the event_data.event index controlled by user-space, which could lead to speculative information leaks.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
