CVE-2024-39499 is a high-severity vulnerability affecting linux linux_kernel. It was published on July 12, 2024 and has a CVSS 3.1 base score of 7.1 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version.
