About this tag
CVE-2025-37833 is a Linux kernel vulnerability in the net/niu driver family, disclosed in May 2025. The defect affects MSIX handling, potentially causing a fatal trap when the kernel reads certain MSIX vector registers before the ENTRY_DATA register, notably on SPARC platforms. Microsoft's MSRC note indicates Azure Linux includes the affected open-source library and is potentially impacted, but this does not guarantee other Microsoft products are unaffected.
