CVE-2026-59691: Out-of-bounds Write in Red Hat Red Hat Enterprise Linux 10CVE-2026-59691 0 CVE-2026-59691 is a heap buffer overflow vulnerability in the GStreamer rfbsrc plugin on Red Hat Enterprise Linux 10. It occurs when connecting to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates. The vulnerability arises because the Hextile background fill path writes 32-bit pixel values into a buffer allocated for 16-bit pixels, causing an out-of-bounds heap write. This can lead to denial of service via process crash and potential memory corruption. Join the discussion | CVE Database V5 | 07/09/2026, 09:34:47 UTC Added: 07/09/2026, 10:35:44 UTC |
