概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點,供應商表示將不會修補。
說明
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。
- 在 Linux 核心中,已解決下列弱點: ACPICA: Revert ACPICA: avoid Info:
mapping multiple BARs. Your kernel is fine. Undo the modifications made in commit d410ee5109a1 (ACPICA:
avoid Info: mapping multiple BARs. Your kernel is fine.). The initial purpose of this commit was to stop memory mappings for operation regions from overlapping page boundaries, as it can trigger warnings if different page attributes are present. However, it was found that when this situation arises, mapping continues until the boundary's end, but there is still an attempt to read/write the entire length of the map, leading to a NULL pointer deference. For example, if a four-byte mapping request is made but only one byte is mapped because it hits the current page boundary's end, a four-byte read/write attempt is still made, resulting in a NULL pointer deference. Instead, map the entire length, as the ACPI specification does not mandate that it must be within the same page boundary. It is permissible for it to be mapped across different regions. (CVE-2024-40984)
請注意,Nessus 依賴供應商報告的套件存在。
