UBUNTU-CVE-2026-53356

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Fix phys BO pread/pwrite with offset sgpage returns struct page pointer not void so the scaling of pread/pwrite is wrong for phys BO and wrong parts of BO would be accessed if non-zero offset is used. Last impacted...

Linux Distros Unpatched Vulnerability : CVE-2026-56786

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - RTKLIB through 2.4.3 contains an out-of-bounds write vulnerability in decodetype1033 function that fails to clamp length counters to destination buffer size,...

PT-2026-52549

Name of the Vulnerable Software and Affected Versions RTKLIB versions prior to 2.4.4 Description An out-of-bounds write occurs in the decode type1033 function because length counters are not clamped to the destination buffer size. This allows an overflow of up to 191 bytes into fixed 64-byte...

Python Liquid: Infinite loop when parsing malformed `{% case %}` tags

Impact Given a malformed % case % tag without associated % when % or % else % block, and no terminating % endcase % tag, Python Liquid hangs in an infinite loop at parse time. This allows malicious template authors to craft templates for a denial of service attack. Patches The issue is fixed in...

Learn from Your Mistakes: Tree-Like Self-Play for Secure Code LLMs

While Large Language Models LLMs excel in code generation, they remain prone to replicating subtle yet critical vulnerabilities endemic to their training data. Current alignment techniques, such as Supervised Fine-Tuning SFT and Reinforcement Learning RL, typically apply coarse-grained optimizati...

PT-2026-44316

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the xfrm AH implementation where the system fails to account for Extended Sequence Number ESN high bits in asynchronous callbacks.

EUVD-2026-32411

In the Linux kernel, the following vulnerability has been resolved: EDAC/versalnet: Fix devicenode leak in mcprobe ofparsephandle returns a devicenode reference that must be released with ofnodeput. The original code never freed r5corenode on any exit path, causing a memory leak. Fix this by usin...

HammerSim: A System-Level Tool to Model RowHammer

Modern architecture research relies on simulators to evaluate system security, yet analyzing emerging hardware vulnerabilities like RowHammer requires full-system visibility. As RowHammer vulnerabilities worsen with continuous technology scaling, existing simulators lack the system-level models...

Astra Linux – Vulnerability in ffmpeg

A issue was discovered in the function filterframe in libavfilter/vflenscorrection.c in Ffmpeg 4.2.1. This issue allows attackers to cause a Denial of Service or other unspecified impacts due to a division by zero...

Fundamental Limitations of Post-Quantum Cryptographic Architectures

Modern lattice-based cryptography, particularly the learning with errors paradigm, relies on injecting artificial noise to secure data against quantum adversaries. This study systematically examines the theoretical and physical boundaries of this noise-reliant model across four interconnected...

PT-2026-36418

In the Linux kernel, the following vulnerability has been resolved: spi: amlogic: spifc-a4: unregister ECC engine on probe failure and remove callback aml sfc probe registers the on-host NAND ECC engine, but teardown was missing from both probe unwind and remove-time cleanup. Add a devm cleanup...

AgentVisor: Defending LLM Agents against Prompt Injection Via Semantic Virtualization

Large Language Model LLM agents are increasingly used to automate complex workflows, but integrating untrusted external data with privileged execution exposes them to severe security risks, particularly direct and indirect prompt injection. Existing defenses face significant challenges in balanci...

PT-2026-35495

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the EDAC/mc component where the error path ordering in the edac mc alloc function is incorrect. When the mci-pvt info allocation fails, the system calls put device,...

AI Chatbots and Trust

All the leading AI chatbots are sycophantic, and that's a problem: Participants rated sycophantic AI responses as more trustworthy than balanced ones. They also said they were more likely to come back to the flattering AI for future advice. And critically ­ they couldn't tell the difference betwe...
