    CVE-2026-80489

    A flaw was found in glibc. This vulnerability allows a remote attacker to cause a denial of service (DoS) by providing specially crafted text to an application that converts text from SHIFT_JISX0213 to UCS-4. The crafted input can lead to a continuous loop of processing, preventing the application from making progress and consuming resources. Exploitation requires specific conditions, including the application retrying conversion after an error with limited output space.
