Cache Leak Vulnerability in Linux Kernel Affects ACPI Components

CVE-2025-38344

What is CVE-2025-38344?

A cache leak was identified within the Linux kernel's ACPI subsystem, where the merging of cache objects for 'Acpi-State', 'Acpi-Parse', and 'Acpi-Parse_ext' led to memory not being freed properly. This issue arises particularly during early abort cases, potentially causing significant memory waste and system instability. The vulnerability relates to improper handling of object caches, leading to residual cache elements that can hinder performance and reliability.
