CVE-2026-25556 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2026-25556 Interim 1 1 2026-03-05T00:16:04Z current 2026-03-05T00:16:04Z 2026-03-05T00:16:04Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2026-25556 MuPDF versions 1.23.0 through 1.27.0 contain a double-free vulnerability in fz_fill_pixmap_from_display_list() when an exception occurs during display list rendering. The function accepts a caller-owned fz_pixmap pointer but incorrectly drops the pixmap in its error handling path before rethrowing the exception. Callers (including the barcode decoding path in fz_decode_barcode_from_display_list) also drop the same pixmap in cleanup, resulting in a double-free that can corrupt the heap and crash the process. This issue affects applications that enable and use MuPDF barcode decoding and can be triggered by processing crafted input that causes a rendering-time error while decoding barcodes.
