CVE-2026-53189 is a use-after-free vulnerability in Linux kernel huge-memory management. The function __split_huge_pmd_locked() updates the file/shared-memory resident-set-size counter after releasing the PMD mapping's folio reference. If folio_put() releases the final reference and frees the folio, mm_counter_file() can subsequently access freed folio state through folio_test_swapbacked(). The fix moves the counter update before folio_put().
