ZDI-26-691: Linux Kernel Netlink-based Wireless Configuration Integer Overflow Local Privilege Escalation Vulnerability

ZDI-26-691: integer overflow in Linux kernel netlink wireless configuration (CVE-2026-53182) allows local privilege escalation by attackers already running high-privileged code; CVSS 8.2.

ZDI advisory ZDI-26-691 discloses an integer overflow in the Linux kernel's netlink-based wireless configuration that allows local attackers to escalate privileges on affected installations. Exploitation requires the attacker to first obtain the ability to execute high-privileged code on the target system. ZDI assigned a CVSS rating of 8.2 and CVE-2026-53182.

ZDI-26-679: Adobe Photoshop DCM JPEG Image Parsing Integer Overflow Remote Code Execution Vulnerability

ZDI disclosed a CVSS 7.8 integer overflow remote code execution flaw (CVE-2026-75862) in Adobe Photoshop DCM JPEG image parsing.

The Zero Day Initiative published advisory ZDI-26-679 describing an integer overflow remote code execution vulnerability in Adobe Photoshop, tracked as CVE-2026-75862 with a CVSS 7.8 score. The flaw occurs while parsing JPEG data in DCM images. Exploitation requires user interaction: the target must visit a malicious page or open a malicious file. No in-the-wild exploitation is reported.
