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 (Linux kernel) involves a race in dup_mmap() that can leave an incomplete mm_struct in an unsafe state when forking or mmap-failure paths are hit. The patch adds MMF_OOM_SKIP to avoid iterating vmas on the out‑of‑memory path and MMF_UNSTABLE to prevent use of a partially initialise...
