CVE-2026-1207496.2 MÉD—
———A flaw was found in D-Bus. With a privileged Monitoring client attached (for example dbus-monitor or busctl monitor), an unprivileged local user can cause dbus-daemon to abort if a driver-originated broadcast such as NameOwnerChanged or ActivatableServicesChanged cannot be delivered to a recipient (for example due to a deny rule or an exceeded outgoing message queue). Driver broadcasts still use serial 0; when delivery fails, composing the monitor error reply asserts reply_serial != 0 and aborts the daemon. This is an incomplete fix for CVE-2023-34969, which only assigned serials for driver messages sent to a single recipient. On the well-known system bus this is a denial of service.9hCVE-2026-1219607.5 ALT39.6%
——12FreeRDP before 3.32.2 contains a denial of service vulnerability in the NLA-enabled shadow server when a CredSSP TSRequest omits negoTokens. Unauthenticated attackers can send a crafted seven-byte TSRequest containing only the version field to trigger a fatal WINPR_ASSERT and abort the server process.21hCVE-2026-1219517.5 ALT36.2%
——11FreeRDP 3.0.0 before 3.32.2 server-side RDP peer input parsing skips the six-byte body of a slow-path input event with an unknown message type without checking it lies within the packet's declared length, causing a WinPR stream assertion failure. A remote RDP client with an active session can send a truncated unknown input event to abort assertion-enabled server processes, causing denial of service.21hCVE-2026-1209567.1 ALT16.8%
——5The MongoDB C Driver does not validate the type or format of a namespace field returned by the server in a query response. A MongoDB endpoint that a client application connects to, without needing any credentials, can return a malformed value in that field. This causes the client application process to terminate, and can also cause the driver to read memory outside an allocated buffer and to send a small amount of the application's own uninitialized heap memory back to the endpoint in a follow-up command. The impact is limited to the process that embeds the driver.3dCVE-2026-1214095.9 MÉD26.2%
——8FreeRDP before 3.32.2 contains a denial of service vulnerability that allows malicious servers or unauthenticated peers to abort clients or proxies via oversized X.224 routing tokens. Attackers can send an oversized LoadBalanceInfo in a Server Redirection PDU, or a 240–247 byte token to a FixedTarget freerdp-proxy, triggering a tpdu_write_header assertion that crashes the process.3dCVE-2026-1214064.3 MÉD14.4%
——4FreeRDP before 3.32.2 allows a client assertion abort because rdpgfx_on_data_received rejects only negative zgfx_decompress status and passes the resulting null output pointer to Stream_StaticConstInit. A malicious RDP server can send a zero-output ZGFX payload on the RDPGFX channel after session activation to terminate the client.3d
