Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: kernel: Be more careful regarding failures with dupmmap and the registration of uprobes. If a memory allocation fails during dupmmap, the map tree can remain in an unsafe state for other iterators besides the exit path. All locks...

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...
