CVE-2026-96280 Flatpak: flatpak: buffer overflow in oci delta stream path names on 32-bit systems

The OCI delta stream parser read sizes as guint64 but passed them to GLib I/O and allocation functions expecting gsize 32 bits on 32-bit systems, causing undersized allocations while subsequent operations use the original 64-bit size, leading to heap buffer overflows. An attacker controlling an O...

CVE-2026-96280

The Flatpak OCI delta stream parser contains a vulnerability where it reads sizes as guint64 but passes them to GLib I/O and allocation functions expecting gsize (32 bits on 32-bit systems). This discrepancy results in undersized allocations while subsequent operations use the original 64-bit siz...
