CVE-2023-53182: 
Linux Kernel vulnerability analysis and mitigation

A vulnerability in the Linux kernel's ACPICA (Advanced Configuration and Power Interface Component Architecture) component was identified and assigned CVE-2023-53182. The issue was discovered on September 15, 2025, and involves undefined behavior when applying a zero offset to a null pointer in the ACPICA code (NVD).

The vulnerability exists in the ACPICA component of the Linux kernel, specifically related to undefined behavior when handling null pointers. The issue was identified through UBSAN (Undefined Behavior Sanitizer) stack traces in Fuchsia, occurring in the acpidsinitamlwalk function. The vulnerability has been assigned a CVSS v3.1 base score of 5.5, indicating moderate severity, with attack vector being Local (L), attack complexity Low (L), and requiring low privileges (PR:L) (Red Hat XML).

The vulnerability could potentially lead to high availability impact (A:H) on affected systems, though there are no reported impacts on confidentiality or integrity (Red Hat XML).

The vulnerability has been resolved in the Linux kernel through a patch that adds a simple check to avoid incrementing a pointer by zero. The fix was implemented in ACPICA commit 770653e3ba67c30a629ca7d12e352d83c2541b1e (NVD).
