xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB key types due to unchecked shift levels

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel XkbNumKbdGroups but CheckKeyTypes does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift...

GHSA-66M8-C62J-H6V5 jxl-oxide: `FrameBuffer::new` creates out-of-bounds slices on overflow

Summary jxl-oxide exposes a public safe API that can construct an undersized FrameBuffer due to unchecked usize multiplication, which immediately trigger panic while initializing the buffer in normal decoding path. Additionally, calling the safe grouped buffer accessors afterward can create inval...

CVE-2026-59093

Weaviate prior to 1.38.0 fails to verify that a principal granting RBAC roles actually has permissions within those roles. The assignRoleToUser and assignRoleToGroup endpoints (POST /authz/users/{id}/assign, /authz/groups/{id}/assign) only check that the caller may assign roles, not the permissio...
