Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: userfaultfd: a race between writeprotect and exitmmap has been fixed. A race may occur when a process exits; its virtual memory addresses are removed by exitmmap, and at the same time, userfaultfdwriteprotect is called. This race...

CVE-2023-53614

Summary: CVE-2023-53614 affects the Linux kernel in the mm/ksm path, where exit_mmap() may teardown VMAs and the maple tree while mmap_lock is held, risking a destroyed maple tree being dereferenced. The fix ensures maple tree validity by checking ksm_test_exit() after obtaining mmap_lock in read...

CVE-2025-38424

CVE-2025-38424 is a Linux kernel fix. The issue arose when perf sampling could access user-space state while the kernel was tearing down a process, risking a crash on ARM64 during do_exit(). The patch changes the teardown order to stop perf earlier in do_exit() and hardens PERF_SAMPLE_CALLCHAIN a...
