Inadequate Encryption Strength Affecting kernel-devel-azure package, versions <4.12.14-8.13.1
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2019-10638 (opens in a new tab)How to fix?
Upgrade SLES:15.1 kernel-devel-azure to version 4.12.14-8.13.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-devel-azure package and not the kernel-devel-azure package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses.
