CVE-2025-38554 is a Use-After-Free (UAF) vulnerability in the Linux kernel's memory management (mm) subsystem. Specifically, it arises from a race condition where a VMA (Virtual Memory Area) can be freed and reallocated while another process is still attempting to access it, leading to a UAF when vma->mm is freed after vma->vm_refcnt is dropped. This vulnerability affects the Linux kernel. Rated with a CVSS score of 7.8 (High), the vulnerability has a local attack vector (AV:L) and low attack complexity (AC:L), requiring low privileges (PR:L) and no user interaction (UI:N). A successful exploit could lead to high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, indicating low public attention at this time.
