SUSE CVE-2026-31481

In the Linux kernel, the following vulnerability has been resolved: tracing: Drain deferred trigger frees if kthread creation fails Boot-time trigger registration can fail before the trigger-data cleanup kthread exists. Deferring those frees until late init is fine, but the post-boot fallback mus...

The vulnerability of the `tracing_err_log_open()` function in the kernel/trace/trace.c module, which supports Linux operating system traceability, allows a malicious actor to cause a service failure.

The vulnerability of the tracingerrlogopen function in the kernel/trace/trace.c module, which supports Linux operating system traceability, is related to the pointer manipulation. Exploiting this vulnerability can allow an attacker to cause a service failure...

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...

CVE-2026-31480

A flaw was found in the Linux kernel. A local attacker or a user with specific privileges could exploit a race condition during CPU hotplug operations, specifically when using the 'osnoise' tracing feature. This vulnerability can lead to a system deadlock, rendering the system unresponsive and...
