CVE-2026-53068
CVE-2026-53068 (Linux kernel, drm/komeda AFBC size check) Root cause: integer overflow in the calculation of the minimum required framebuffer size (AFBC payload size + framebuffer offset) during validation, allowing a malformed, undersized drm_gem_object to slip through. Impact: potential out-of-...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerabilities have been resolved: drm, fbcon, vgaswitcheroo: Avoid race conditions in the fbcon setup process. Protect the vgaswitcherooclientfbset function with a console lock. This prevents out-of-band OOB access in the fbconremapall function. Without holdin...
Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerabilities have been resolved: fbdev: vt8500lcdfb: fixed the issue where dmafreecoherent was not called when memory was freed. The fbi-fb.screenbuffer is allocated using dmaalloccoherent, but it is not freed if an error path occurs...
Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: fbdev: bitblit: In the bitPutcs function, the bound-check glyph index was derived from the character value masked by 0xff or 0x1ff. This may lead to reading beyond the end of the built-in font array, exceeding the actual number o...
Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: fbcon: Set fbdisplayi-mode to NULL when the mode is released. Recently, we discovered the following issue through syzkaller: BUG: KASAN: Slab-use-after-free in fbmodeisequal+0x285/0x2f0 A read of size 4 at address ff11000001b3c69...
DEBIAN-CVE-2026-52720
A heap buffer overflow vulnerability was found in GStreamer's librfb RFB/VNC client. The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a...

Amazon Linux 2 : libvncserver, --advisory ALAS2-2026-3331 (ALAS-2026-3331)
The version of libvncserver installed on the remote host is prior to 0.9.9-14. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3331 advisory. LibVNCClient is a library for easy implementation of a VNC client. In 0.9.15 and earlier, LibVNCClient's Tight encoding decod...
OESA-2026-2490 libvncserver security update
libvncserver is a set of programs using the RFB Remote Frame Buffer protocol. They are designed to "export" a frame buffer via net: you set up a server and can connect to it via VNC viewers. If the server supports WebSockets which LibVNCServer does, you can also connect using an in-browser VNC...

CVE-2026-46191
A flaw was found in the Linux kernel's framebuffer console fbcon component. When console rotation fails, the fbconrotatefont function may keep an old font buffer that is too small for the rotated font. A local user printing to the rotated console with a high character code can trigger an...
