CVE-2024-42154 Open this link in a new tabHow to fix?
Upgrade RHEL:8 kernel-cross-headers to version 0:4.18.0-477.74.1.el8_8 or higher.
This issue was patched in RHSA-2024:6993.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
tcp_metrics: validate source addr length
I don't see anything checking that TCP_METRICS_ATTR_SADDR_IPV4 is at least 4 bytes long, and the policy doesn't have an entry for this attribute at all (neither does it for IPv6 but v6 is manually validated).
