Inspektor Gadget uses unsanitized ANSI Escape Sequences In `columns` Output Mode

Description String fields from eBPF events in columns output mode are rendered to the terminal without any sanitization of control characters or ANSI escape sequences. Therefore, a maliciously forged – partially or completely – event payload, coming from an observed container, might inject the...

In the Linux kernel, the following vulnerability has been resolved: tracing/dma: Cap dmamapsg tracepoint arrays to prevent buffer overflow The dmamapsg tracepoint can trigger a perf buffer overflow when tracing large scatter-gather lists. With devices like virtio-gpu creating large DRM buffers,...

CVE-2026-23309 tracing: Add NULL pointer check to trigger_data_free()

In the Linux kernel, the following vulnerability has been resolved: tracing: Add NULL pointer check to triggerdatafree If triggerdataalloc fails and returns NULL, eventhisttriggerparse jumps to the outfree error path. While kfree safely handles a NULL pointer, triggerdatafree does not. This cause...

CVE-2026-23309

CVE-2026-23309 refers to a Linux kernel vulnerability in the tracing subsystem. The issue was a NULL pointer dereference in trigger_data_free() when data->cmd_ops->set_filter is evaluated after a failed trigger_data_alloc() and returning NULL. The root cause was that trigger_data_free() did...

Auditing MCP Servers for Over-Privileged Tool Capabilities

The Model Context Protocol MCP has emerged as a standard for connecting Large Language Models LLMs to external tools and data. However, MCP servers often expose privileged capabilities, such as file system access, network requests, and command execution that can be exploited if not properly...

CVE-2026-23217

CVE-2026-23217 relates to the Linux kernel on RISC-V where tracing the sbi_ecall functions can cause a deadlock in the snapshot path. The root cause is that sbi_ecall triggers a ringbuffer snapshot which may re-enter __sbi_ecall via an IPI, creating an endless loop when initial __sbi_ecall is pre...
