CVE-2025-22064 is a Linux kernel vulnerability in the netfilter/nf_tables subsystem, described as 'don't unregister hook when table is dormant.' Microsoft has publicly attested that Azure Linux includes the affected open-source library and is therefore potentially impacted. However, this attestation does not guarantee that no other Microsoft product contains the same vulnerable code. The discussion on WindowsForum clarifies the scope of Microsoft's statement, emphasizing that it is accurate for Azure Linux customers but not an exclusive claim. Users should assess their exposure based on their specific Linux deployments and apply relevant patches.
