CVE-2026-3146Public exploit

Local process crash via empty matrix header

Published Feb 25, 2026 · Updated Feb 25, 2026

NULL pointer dereference in libvips 8.18.0 and earlier allows local users to crash an invoking process with an empty matrix file. vips_foreign_load_matrix_header passes a NULL line returned by vips_sbuf_get_line_copy to parse_matrix_header, whose strchr call dereferences it. Exploitation requires local ability to supply an empty matrix file to a libvips consumer and interrupts only the process that loads it.
