CVE-2026-751595.9 MED—
———An unauthenticated client that can reach a MongoDB Connector for BI deployment configured with Kerberos authentication may cause mongosqld to terminate when a crafted authentication exchange encounters a specific GSSAPI error-handling condition. This can interrupt BI Connector availability until the process restarts.6hCVE-2026-478957.5 HIG49.3%
——15In strongSwan before 6.0.7, identity parsing/cloning is mishandled. Parsed EAP-Identities that result in an empty but non-NULL encoding are not correctly cloned and trigger a double-free once the duplicates are destroyed.3dCVE-2026-452025.5 MED4.4%
——1Software installed and run as a non-privileged user may conduct GPU system calls which cause GPU memory leaks and possible kernel heap corruption.
Scenario caused by memory free paths not maintaining state data of upgraded higher order allocations. This could cause memory leak or double free event.6hCVE-2026-63652—26.8%
——8FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, rdpsnd_server_recv_formats in channels/rdpsnd/server/rdpsnd_main.c frees context->client_formats on a malformed Client Audio Formats PDU without clearing the owning pointer or num_client_formats. An authenticated RDP client can trigger an error such as a cbSize larger than the remaining record, leave the dangling pointer in the server context, and cause rdpsnd_server_context_free to free the same allocation again at session teardown. This reliably terminates the server and can create allocator-dependent heap corruption. This issue is fixed in version 3.28.0.8dCVE-2026-186635.9 MED35.9%
——11A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function frees the parsed controls array on the Session Tracking critical-control rejection path without clearing the SLAPI_REQCONTROLS pblock slot. Operation teardown then frees the same pointer again, causing a double-free. An unauthenticated remote attacker can trigger this with a single BIND request carrying a critical Session Tracking control, resulting in heap corruption and potential denial of service.13dCVE-2026-657807.0 HIG9.7%
——3Double free in Windows Autopilot allows an authorized attacker to elevate privileges locally.14d
