Linux Distros Unpatched Vulnerability : CVE-2024-40984

medium Nessus Plugin ID 228506

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In the Linux kernel, the following vulnerability has been resolved: 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
