cve 2025 38212

CVE-2025-38212 is a use-after-free vulnerability in the Linux kernel's IPC subsystem. The Linux kernel team has released a fix, and Microsoft's public CVE entry identifies Azure Linux as a product that includes the affected open-source library and is therefore potentially impacted. This makes Azure Linux a confirmed, high-priority target for patching. However, the entry does not technically prove that no other Microsoft product or artifact contains the same vulnerable kernel code. Users should also verify other Microsoft-supplied kernels and images, such as WSL2 kernels and Azure VM or marketplace kernels, to ensure comprehensive coverage against this vulnerability.
