Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：vmalloc: fix buffer overflow in vrealloc_node_align() Commit 4c5d3365882d (mm/vmalloc: allow to set node and align in vrealloc) added the ability to force a new allocation if the current pointer is on the wrong NUMA node, or if an alignment constraint is not met, even if the user is shrinking the allocation. On this path (need_realloc), the code allocates a new object of 'size' bytes and then memcpy()s 'old_size' bytes into it. If the request is to shrink the object (size < old_size), this results in an out-of-bounds write on the new buffer. Fix this by bounding the copy length by the new allocation size. (CVE-2026-46281)

請注意，Nessus 依賴供應商報告的套件存在。
