CVE-2026-59691 on CTRL-OS 26.05

Aliases: CVE-2026-59691

Packages: gst_all_1.gst-plugins-bad

Status: Plausible

Advisory Information

A heap buffer overflow vulnerability was found in GStreamer's rfbsrc plugin. When a client connects to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates, the Hextile background fill path writes 32-bit pixel values into a buffer allocated for 16-bit pixels. This type mismatch causes an out-of-bounds heap write that can lead to denial of service (process crash) and potential memory corruption.
