CVE-2026-46182

The CVE-2026-46182 issue affects the Linux kernel component pseries/papr-hvpipe . The root cause is that a local kernel stack variable hdr (papr_hvpipe_hdr) is allocated on the stack and only hdr.version and hdr.flags are initialized, leaving reserved padding bytes uninitialized. When copied to u...
