xorg: xwayland: X.Org X server: Use-after-free vulnerability leads to server crash and potential memory corruption

A flaw was found in the X.Org X server. This use-after-free vulnerability occurs in the XSYNC fence triggering logic, specifically within the miSyncTriggerFence function. An attacker with access to the X11 server can exploit this without user interaction, leading to a server crash and potentially...

xorg: xwayland: X.Org X server: Denial of Service via integer underflow in XKB compatibility map handling

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of servi...

EUVD-2026-23644

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 36aa5c7ec8a2bb35f6fb867a1177a6f141156b02, the XWD codec resolves pixel format based on pixmapdepth but the byte-swap code uses bitsperpixel independently. When...

CVE-2026-40492

SAIL’s CVE-2026-40492 describes a heap buffer overflow in the XWD decoder caused by a mismatch: when pixmap_depth=8, the code uses bits_per_pixel=32 for byte-swapping, leading to memory access beyond the 1-byte/pixel buffer. The issue affects versions prior to the patch 36aa5c7ec8a2bb35f6fb867a11...
