CVE-2026-31448

A flaw was found in the Linux kernel's ext4 filesystem. When creating a directory or node, if an extent insertion fails, the system may not properly clear residual data. This can lead to a situation where both directory and extended attribute xattr blocks simultaneously use the same memory buffer...

CVE-2026-31448

CVE-2026-31448 concerns the Linux kernel ext4 filesystem. The issue arises on mkdir/mknod when an extent insertion fails and ext4_ext_map_blocks() reclaims blocks without removing corresponding data from the extent tree, allowing the same physical block to be referenced by both directory and xatt...

TL-RL-FusionNet: An Adaptive and Efficient Reinforcement Learning-Driven Transfer Learning Framework for Detecting Evolving Ransomware Threats

Modern ransomware exhibits polymorphic and evasive behaviors by frequently modifying execution patterns to evade detection. This dynamic nature disrupts feature spaces and limits the effectiveness of static or predefined models. To address this challenge, we propose TL-RL-FusionNet, a reinforceme...

freerdp: FreeRDP: Heap buffer overflow leads to denial of service and potential code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious server can exploit a client-side heap buffer overflow vulnerability in the RDPGFX ClearCodec decode path. This occurs when maliciously crafted residual data causes out-of-bounds writes during color...

Discovering Universal Activation Directions for PII Leakage in Language Models

Modern language models exhibit rich internal structure, yet little is known about how privacy-sensitive behaviors, such as personally identifiable information PII leakage, are represented and modulated within their hidden states. We present UniLeak, a mechanistic-interpretability framework that...
