About this tag
CVE-2025-32052 is a heap buffer over-read vulnerability in the libsoup library's sniff_unknown() routine. It has been patched across Linux distributions and is specifically noted by Microsoft as affecting Azure Linux. However, Azure Linux is not the only Microsoft-delivered component that may contain libsoup, so organizations should treat this as a supply-chain and detection issue rather than a single-product checklist. Discussions on WindowsForum.com emphasize the importance of software bill of materials (SBOMs) and broader supply-chain defense strategies for addressing this vulnerability.
