NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-4.19 package and not the linux-4.19 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808.
