Security readout for executives and security teams
Plain-English summary
CVE-2026-24823 is a critical memory-safety flaw in FASTSHIFT X-TRACK through v2.7. A crafted PNG-processing input could trigger out-of-bounds memory access, potentially affecting confidentiality, integrity, and availability. The CVSS 4.0 score is 10.0. No cited source states active exploitation.
Executive priority
Treat as urgent if X-TRACK is used in products or systems processing untrusted image data. The maximum CVSS score and no-interaction remote vector warrant rapid inventory and remediation planning. Do not assume exploitation is occurring without new evidence.
Technical view
The CVE describes CWE-120/CWE-787 in X-TRACK PNG decoding code under Software/X-Track/USER/App/Utils/lv_img_png/PNGdec/src, associated with inflate.C. It is characterized as out-of-bounds write and classic buffer overflow due to buffer copy without input-size checking. The CVSS vector indicates network attackability, low complexity, no privileges, and no user interaction.
Likely exposure
Organizations using FASTSHIFT X-TRACK through v2.7 are potentially affected. Exposure depends on whether the vulnerable PNG decoding path is present and reachable in deployed builds or products. The source bundle does not identify specific deployment models, downstream products, or internet-facing instances.
Exploitation context
The CVSS vector indicates remote, low-complexity exploitation without privileges or user interaction. However, the provided sources do not include a proof of concept, exploitation details, or evidence of active exploitation. CISA KEV status in the bundle is false.
Researcher notes
The source data is limited. The affected statement says X-TRACK through v2.7, while the affected version array contains “0,” creating ambiguity. The referenced GitHub pull request is tagged as a patch source, but the bundle does not confirm release availability or merge status.
Mitigation direction
- Identify X-TRACK versions in use and prioritize systems through v2.7.
- Review the FASTSHIFT pull request referenced as the patch source.
- Check FASTSHIFT project guidance for fixed versions or recommended updates.
- If updates are unavailable, reduce exposure to untrusted PNG inputs where feasible.
- Monitor CVE and vendor references for revised remediation details.
Validation and detection
- Inventory repositories, firmware, or products that embed FASTSHIFT X-TRACK.
- Confirm whether vulnerable lv_img_png PNGdec source modules are included.
- Verify whether inflate.C changes from the referenced pull request are applied.
- Assess whether untrusted PNG data can reach the affected decoder.
- Track CVE updates for corrected affected-version or patch information.
