CVE-2026-11478: Inefficient Regular Expression Complexity in kokke tiny-regex-c
CVE-2026-11478 is a medium severity vulnerability in the kokke tiny-regex-c library affecting the matchstar function in re. c. It causes inefficient regular expression complexity, potentially leading to performance degradation. The attack requires local access and low privileges, with no user interaction needed. Exploit code is publicly available, but no official patch or remediation has been provided yet. The project uses a rolling release model, so specific fixed versions are not identified. No known exploits in the wild have been reported.

Technical Summary
This vulnerability in kokke tiny-regex-c up to commit f2632c6d9ed25272987471cdb8b70395c2460bdb involves inefficient regular expression complexity in the matchstar function of the Pattern Handler component (re.c). The flaw can be triggered locally by an attacker with low privileges, potentially causing performance issues due to excessive resource consumption during regex processing. The vulnerability has been publicly disclosed with exploit code available, but the vendor has not yet responded or issued a fix. Due to the rolling release strategy, affected or patched versions are not clearly defined.
Potential Impact
The vulnerability allows a local attacker with low privileges to cause inefficient regex processing, which may degrade application performance or lead to denial of service conditions locally. There is no indication of remote exploitation, privilege escalation, or data compromise. No known active exploitation in the wild has been reported.
Mitigation Recommendations
No official patch or remediation is currently available, and the vendor has not responded to the issue report. Users should monitor the kokke tiny-regex-c project for updates or fixes. Until a fix is released, limiting local access to trusted users can reduce risk. Patch status is not yet confirmed — check the vendor advisory or project repository for current remediation guidance.
