Exploitation evidence

Disclosed: evidence found.
CVE published 15 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

An official security update is available from Red Hat for java-1.8.0-openjdk packages across affected Red Hat Enterprise Linux versions. Users should apply this update following Red Hat's guidance to remediate the vulnerabilities and bug fixes. Ensure all previously released errata are applied before updating. No additional mitigation actions are specified by the vendor.

Description

A security update for java-1.8.0-openjdk addresses multiple vulnerabilities including issues with glyph drawing, TLS protocol support, and scripting support. The update also fixes a bug related to hostname resolution behavior on certain system configurations. The vulnerabilities are identified by CVE-2025-30749, CVE-2025-30754, CVE-2025-30761, and CVE-2025-50106. This update is rated as having an important security impact by Red Hat and affects various Red Hat Enterprise Linux 8 and 9 versions and related distributions.

Impact

The vulnerabilities fixed by this update affect the Java runtime environment and could potentially impact applications relying on glyph rendering, TLS protocol handling, and scripting capabilities. The hostname resolution bug could cause inconsistent hostname information in certain network configurations. Red Hat rates the security impact as Important, indicating a significant but not critical risk. There are no known exploits in the wild at this time.

Summary

The java-1.8.0-openjdk packages, providing OpenJDK 8 Java Runtime Environment and Software Development Kit, have multiple security fixes. These include improvements to glyph drawing (CVE-2025-30749 and CVE-2025-50106), enhancements to TLS protocol support (CVE-2025-30754), and scripting support improvements (CVE-2025-30761). Additionally, a bug fix corrects the behavior of java.net.InetAddress.getLocalHost().getHostName() to consistently return the short hostname across IPv4 and IPv6 interfaces, aligning behavior across platforms. The update is provided by Red Hat for multiple versions of Red Hat Enterprise Linux and related products.

CWE-122Heap-based Buffer Overflow (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #16
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
Pre-design: Use a language or compiler that performs automatic bounds checking.
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…
