Open-source software (OSS) supply chain security has become a topic of concern for organizations. Patching an OSS vulnerability can require updating other dependent software products in addition to the original package. However, the landscape of OSS dependencies is not well explored: we do not know what packages are most critical to patch, hindering efforts to improve OSS security where it is most needed. There is thus a need to understand OSS usage in major software and device makers' products. Our work takes a first step toward closing this knowledge gap. We investigate published OSS dependency information for 108 major software and device makers, cataloging how available and how detailed this information is and identifying the OSS packages that appear the most frequently in our data.
