Technical details
The vulnerability is an integer overflow or wraparound condition in Lightroom Classic's file handling code. When processing a malicious file containing crafted data, an integer calculation overflows, leading to a memory corruption condition that can be exploited to achieve arbitrary code execution in the context of the current user. The attack requires user interaction—a victim must explicitly open the malicious file. The vulnerability affects Lightroom Classic, and patches should be available through Adobe's standard security update process (APSB26-94).
