CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the JavaFX component in Oracle JavaFX. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
2) Improper input validation (CVE-ID: CVE-2026-91402)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the JavaFX component in Oracle Java SE, JavaFX, Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
3) Out-of-bounds read (CVE-ID: CVE-2026-46470)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to out-of-bounds read in the MOV/MP4 demuxer audio channel layout parsing code when parsing a crafted file that uses an invalid defined layout index. A remote attacker can supply a specially crafted media file to cause a denial of service.
Successful exploitation may also disclose sensitive information through out-of-bounds reads.
4) Improper input validation (CVE-ID: CVE-2026-91418)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the ImageIO component in Oracle Java SE, JavaFX, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
5) Improper input validation (CVE-ID: CVE-2026-91385)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the JavaFX component in Oracle Java SE, JavaFX, Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
6) Type confusion (CVE-ID: CVE-2026-6732)
CWE-ID: CWE-843 - Type confusion
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a type confusion error when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. A remote attacker can supply a specially crafted XML document to the application and perform a denial of service attack.
7) Protection Mechanism Failure (CVE-ID: CVE-2026-43660)
CWE-ID: CWE-693 - Protection Mechanism Failure
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to prevent CSP enforcement.
The vulnerability exists due to insufficient implementation of security measures in WebKit. A remote attacker can trick the victim into visiting a specially crafted website and prevent Content Security Policy from being enforced.
