CVE-2025-21709

CVE-2025-21709 — Linux kernel vulnerability. Root cause: a dup_mmap() allocation failure can leave the maple tree in an unsafe state, enabling a partially initialised mm_struct to be observed via rmap, and a race related to uprobes remains after prior fixes. The patch introduces MMF_OOM_SKIP to a...
