nano: A flaw was found in nano
CVE-2026-6843 is fixed in 6 products on 1 platform, first by FEDORA-2026-D0A0F1C3D2, released April 30, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in nano. A local user could exploit a format string vulnerability in the `statusline()` function. By creating a directory with a name containing `printf` specifiers, the application attempts to display this name, leading to a segmentation fault (SEGV). This results in a Denial of Service (DoS) for the `nano` application.
