CVE-2026-9960
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
An integer overflow in PDFium in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to execute arbitrary code inside a sandbox via a crafted font file.
Risk Assessment
The risk involves arbitrary code execution within the browser sandbox, potentially leading to privilege escalation and further system compromise.
Recommendation
Immediately update Google Chrome to version 148.0.7778.216 or later. Ensure updates are applied to all workstations.

A use after free in PDFium in Google Chrome prior to version 55.0.2883.75 for Mac, Windows, and Linux, and prior to version 55.0.2883.84 for Android allows a remote attacker to potentially exploit heap corruption via a crafted PDF file.
- CVE-2016-5154High
Multiple heap-based buffer overflows in PDFium, used in Google Chrome before version 53.0.2785.89 on Windows and OS X and before version 53.0.2785.92 on Linux, allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted JBig2 image.
- CVE-2016-5151High
PDFium in Google Chrome before version 53.0.2785.89 on Windows and OS X and before version 53.0.2785.92 on Linux mishandles timers, allowing remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted PDF document.
- CVE-2016-1651High
In PDFium, used in Google Chrome before version 50.0.2661.75, the sycc420_to_rgb and sycc422_to_rgb functions are not properly implemented, allowing remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via crafted JPEG 2000 data in a PDF document.
- CVE-2016-1613High
Multiple use-after-free vulnerabilities in the formfiller implementation in PDFium, as used in Google Chrome before version 48.0.2564.82, allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document.
- CVE-2015-6775High
In PDFium, used in Google Chrome before version 47.0.2526.73, the fxjs_v8.cpp file does not use signatures, allowing remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that leverage 'type confusion.'
- CVE-2015-1279High
Integer overflow in the CJBig2_Image::expand function in PDFium, used in Google Chrome before version 44.0.2403.89, may lead to denial of service (heap-based buffer overflow) or other unspecified impacts due to large height and stride values.
- CVE-2015-1259High
PDFium, as used in Google Chrome before version 43.0.2357.65, does not properly initialize memory, allowing remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.
