In the Linux kernel, the following vulnerability has been resolved: net: atm: fix crash due to unvalidated vcc pointer in sigdsend Reproducer available at 1. The ATM send path sendmsg - vccsendmsg - sigdsend reads the vcc pointer from msg-vcc and uses it directly without any validation. This...

freerdp: FreeRDP has a heap-use-after-free in ainput_send_input_event

A heap buffer use after free has been discovered in FreeRDP. ainputsendinputevent caches channelcallback in a local variable and later uses it without synchronization; a concurrent channel close can free or reinitialize the callback, leading to a use after free...

freerdp: FreeRDP heap-use-after-free

A heap use after free flaw has been discovered in FreeRDP. A race in the serial channel IRP thread tracking allows a heap use‑after‑free when one thread removes an entry from serial-IrpThreads while another reads it...

freerdp: FreeRDP has a heap-use-after-free in video_timer

A use after free flaw has been discovered in FreeRDP. The videotimer can send client notifications after the control channel is closed, dereferencing a freed callback and triggering a use after free. A malicious server can trigger a client‑side heap use after free causing a crash DoS...

freerdp: FreeRDP has a Heap-use-after-free in play_thread

A heap use after free has been discovered in FreeRDP. The RDPSND async playback thread can process queued PDUs after the channel is closed and internal state is freed, leading to a use after free in rdpsndtreatwave...

freerdp: FreeRDP has a heap-use-after-free in urb_bulk_transfer_cb

A heap buffer use after free has been discovered in FreeRDP. Asynchronous bulk transfer completions can use a freed channel callback after URBDRC channel close, leading to a use after free in urbwritecompletion...

Hiding an Ear in Plain Sight: On the Practicality and Implications of Acoustic Eavesdropping with Telecom Fiber Optic Cable

Optical fibers are widely regarded as reliable communication channels due to their resistance to external interference and low signal loss. This paper demonstrates a critical side channel within telecommunication optical fiber that allows for acoustic eavesdropping. By exploiting the sensitivity ...

Anamorphic Encryption with CCA Security: A Standard Model Construction

Anamorphic encryption serves as a vital tool for covert communication, maintaining secrecy even during post-compromise scenarios. Particularly in the receiver-anamorphic setting, a user can shield hidden messages even when coerced into surrendering their secret keys. However, a major bottleneck i...

OpenClaw Access Control Error Vulnerability (CNVD-2026-16624)

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. A security vulnerability exists in versions prior to OpenClaw 2026.3.12 that stems from a weak authorization issue in the Zalouser whitelisting schema that matches variable group display names instead of stable group...

OpenClaw: Shared-secret comparison call sites leaked length information through timing

Summary Before OpenClaw 2026.4.2, several shared-secret comparison call sites still used early length-mismatch checks instead of the shared fixed-length comparison helper. Those paths could leak secret-length information through measurable timing differences. Impact The affected paths exposed a...

OpenClaw: Untrusted workspace channel shadows could execute during built-in channel setup

Summary Before OpenClaw 2026.4.2, built-in channel setup and login could resolve an untrusted workspace channel shadow before the plugin was explicitly trusted. A malicious workspace plugin that claimed a bundled channel id could execute during channel setup even while still disabled. Impact A...
