Description

This security bulletin contains information about 8 vulnerabilities.


1) Incorrect Calculation of Buffer Size (CVE-ID: CVE-2026-1188)

CWE-ID: CWE-131 - Incorrect Calculation of Buffer Size

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to API function to return the textual names of all supported processor features was not accounting for the separator inserted between processor features. A remote attacker can pass specially crafted data to the application, trigger the incorrect calculation of buffer size and execute arbitrary code on the target system.


2) Improper input validation (CVE-ID: CVE-2026-22007)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Security component in Oracle GraalVM Enterprise Edition. A local non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.


3) Improper input validation (CVE-ID: CVE-2026-22013)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the JGSS component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.


4) Improper input validation (CVE-ID: CVE-2026-22016)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
