Stegano

Stegano Stegano, a pure Python Steganography module. Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. Consequently, functions provid...

Astra Linux – vulnerability in linux-6.1, linux-6.12, linux-6.18

In the Linux kernel, the following vulnerability has been resolved: Tracing: Free histogram var refs regardless of how often they are referenced Using the same variable three or more times in one hist triggers leaks the variable reference and its strings when the trigger is removed. Commit...

CVE-2026-99233

A flaw was found in the Linux kernel's event tracing subsystem. The kernel fails to properly verify the unique identity of trace events when updating reference counters for histogram triggers, comparing only their names. A local user with access to the tracing interface can exploit this by...

PT-2026-135524

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the tracing histogram field variables. The create field var hist function incorrectly saves a pointer to a compatible histogram instead of the event file...

CVE-2026-99140

A flaw was found in the Linux kernel's tracing subsystem. A local user with access to the tracing interface can cause a Denial of Service DoS due to a race condition when attaching histogram triggers to filtered events. Under specific timing conditions, buffered trace events are processed without...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: fix memory leak in mwifiexhistogramread Always free the zeroed page on return from ‘mwifiexhistogramread’...

Astra Linux – vulnerability in linux, linux-5.10

In the Linux kernel, the following vulnerability has been resolved: tracing/histogram: Fix a potential memory leak for kstrdup kfree is missing on an error path to free the memory allocated by kstrdup: p = param = kstrdupdata-paramsi, GFPKERNEL; So it is better to free it via kfreep...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: Tracing: Ensure visibility when inserting an element into tracingmap. Running the following two commands in parallel on a multi-processor AArch64 machine may occasionally generate an unexpected warning regarding duplicate...

yopass Prometheus metrics middleware allows remote memory exhaustion through unbounded method labels

The Prometheus metrics middleware in pkg/server/server.go used r.Method directly as a label value on request counter and duration histogram metrics. Since the mux catch-all route matches any HTTP method, an unauthenticated attacker can send requests with arbitrary method strings e.g. curl -X "M1"...

SUSE CVE-2026-97921

In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram the field rejected for a bad modifier Writing a hist trigger whose value or variable carries a modifier that is not allowed there leaks the fields that were built for it. createvalfield takes the field fro...

SUSE CVE-2026-97922

In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram var refs regardless of how often they are referenced Using the same variable three or more times in one hist trigger leaks the variable reference and its strings when the trigger is removed. commit...

SUSE CVE-2026-97936

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix memory corruption from the histogram stacktrace modifier parsefield sets HISTFIELDFLSTACKTRACE from the ".stacktrace" modifier before it looks the field name up, and nothing afterwards checks that the name resolved t...

CVE-2026-97922

A flaw was found in the Linux kernel's tracing subsystem. This vulnerability allows a privileged local user to cause a Denial of Service DoS through memory exhaustion. By repeatedly creating and removing histogram event triggers that reference the same variable multiple times, the kernel fails to...

CVE-2026-97921

A flaw was found in the Linux kernel's tracing subsystem. When configuring event histogram triggers, specifying an unpermitted modifier for a value or variable fails to release previously allocated memory on error. A local user with tracing access can exploit this flaw by repeatedly submitting...

CVE-2026-97920

A flaw was found in the Linux kernel. A local user could trigger this vulnerability by reading an event tracing histogram file when a memory allocation failure occurs. Because an error code overwrites the entry counter during cleanup, the system treats the error as an extremely large positive...

CVE-2026-97919

A flaw was found in the Linux kernel's tracing subsystem. When creating a named histogram trigger, the kernel registers the trigger before completing its setup. If initialization fails, the object is freed without being removed from the global tracking list. A local attacker can exploit this flaw...
