Trojan Hippo: Weaponizing Agent Memory for Data Exfiltration

Memory systems enable otherwise-stateless LLM agents to persist user information across sessions, but also introduce a new attack surface. We characterize the Trojan Hippo attack, a class of persistent memory attacks that operates in a more realistic threat model than prior memory poisoning work:...

Linux Distros Unpatched Vulnerability : CVE-2026-43020

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: MGMT: validate LTK encsize on load Load Long Term Keys stores the user-provided encsize and later uses it to size fixed-size stack operations when...

Linux Distros Unpatched Vulnerability : CVE-2026-43044

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - crypto: caam - fix DMA corruption on long hmac keys When a key longer than block size is supplied, it is copied and then hashed into the real key. The memory...

CVE-2026-43020

A flaw was found in the Linux kernel's Bluetooth management MGMT component. An attacker could exploit a vulnerability in how Long Term Keys LTK are loaded. By providing an oversized encryption size, a stack buffer overflow can occur, potentially leading to a denial of service...

CVE-2026-43044

In the Linux kernel, the following vulnerability has been resolved: crypto: caam - fix DMA corruption on long hmac keys When a key longer than block size is supplied, it is copied and then hashed into the real key. The memory allocated for the copy needs to be rounded to DMA cache alignment, as...

CVE-2026-43044

The CVE-2026-43044 issue affects the Linux kernel's crypto: caam module. When processing HMAC keys longer than the block size, the copied key’s memory was not properly aligned for DMA, risking corruption of adjacent memory. The vulnerability’s root cause was the allocation of a copy that relied o...

CVE-2026-43020 Bluetooth: MGMT: validate LTK enc_size on load

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: validate LTK encsize on load Load Long Term Keys stores the user-provided encsize and later uses it to size fixed-size stack operations when replying to LE LTK requests. An encsize larger than the 16-byte key...

CVE-2026-43020

CVE-2026-43020 concerns the Linux kernel Bluetooth MGMT path: load-time Long Term Keys can overflow a fixed-size stack buffer if enc_size exceeds the 16-byte key buffer. The root cause is validation of enc_size not rejecting oversized values during management LTK record validation, allowing inval...
