CVE-2026-91752: GNU libextractor < 1.15 Stack Overflow via OLE2
GNU libextractor before 1.15 has a stack-based buffer overflow (CVE-2026-91752) in its OLE2 parser, triggerable via crafted files.
A stack-based buffer overflow was identified in GNU libextractor's OLE2 plugin in versions prior to 1.15, assigned CVE-2026-91752. The flaw resides in the process_star_office function, which sizes a variable-length stack array using attacker-controlled OLE2 stream data. Attackers can craft malicious OLE2/StarOffice files to trigger the overflow. The issue was disclosed on the oss-security mailing list by researcher Haitam Lazaar on September 16, 2026.

Google Chrome 153 Released With 230 Security Fixes and Zero-Day Exploited in the Wild
Google released Chrome 153 with 230 security fixes, patching CVE-2026-87491, a V8 out-of-bounds write zero-day actively exploited in the wild.
Google shipped Chrome 153 (153.0.8010.36/.37) for Windows, macOS, and Linux with 230 security fixes, including CVE-2026-87491, a medium-severity V8 out-of-bounds write being exploited in the wild. The release also fixes five critical vulnerabilities: four in WebGL (two use-after-frees, an out-of-bounds write, a buffer overflow) and one use-after-free in Cast. High-severity V8 use-after-free and type-confusion defects are among the fixes, and Google has restricted technical details until most users are patched. Administrators should verify deployed versions on managed endpoints, as Chrome-derived browsers may follow different patch schedules.

Nintendo Switch system update 23.0.0 fixes CVE-2026-82079, a stack-based buffer overflow in local wireless networking abused via the QR code sharing process, including Album's 'Send to Smartphone' and Mario Kart Live pairing. A nearby attacker who scans the displayed QR code can send crafted traffic and use return-oriented programming to achieve arbitrary code execution.
