Exploitation evidence

Disclosed: evidence found.
CVE published 5 May 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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.

What to do

Upgrade the Red Hat redhat/libraw package to 9.4.1.

AI-suggested

Red Hat has released updated LibRaw packages for Red Hat Enterprise Linux 9.4 Extended Update Support and related variants that address these vulnerabilities. Users should apply the security updates as described in Red Hat advisory RHSA-2026:13870 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patches.

Description

LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). Security Fix(es): * LibRaw: LibRaw: Arbitrary code execution via a specially crafted malicious file (CVE-2026-24450) * LibRaw: LibRaw: Arbitrary code execution via heap-based buffer overflow in lossless JPEG loading (CVE-2026-21413) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code on the affected system. This could lead to full compromise of the system running vulnerable versions of LibRaw. The vulnerabilities specifically impact the processing of maliciously crafted RAW image files, potentially enabling remote code execution if such files are processed.

Summary

LibRaw contains two security flaws: CVE-2026-24450 allows arbitrary code execution through a specially crafted malicious file, and CVE-2026-21413 involves a heap-based buffer overflow in lossless JPEG loading that also leads to arbitrary code execution. These vulnerabilities have been rated as important by Red Hat Product Security. The issues affect Red Hat Enterprise Linux 9.4 Extended Update Support and related product variants. Red Hat has issued an advisory (RHSA-2026:13870) and released updated LibRaw packages to fix these vulnerabilities.

CWE-787Out-of-bounds Write (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #5
The product writes data past the end, or before the beginning, of the intended buffer.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
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…

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
