OESA-2022-1880 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A race condition in perfeventopen which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution,...

DEBIAN-CVE-2022-1462

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flushtoldisc function. This flaw allows a local user to crash the...

CVE-2022-1462

CVE-2022-1462 is an out-of-bounds read in the Linux kernel TeleTYpe subsystem triggered by a race using ioctls (TIOCSPTLCK, TIOCGPTPEER, TIOCSTI, TCXONC). Local users can crash the system or read unauthorized memory. Public advisories link this CVE to Linux kernel versions across multiple distrib...

Security Bulletin: A vulnerability in IBM Spectrum Scale packaged in IBM Elastic Storage System 3000 cause denial of service in kernel ( CVE-2020-4411)

Summary A security vulnerability has been identified in all levels of IBM Elastic Storage System 3000 that could allow a local attacker to cause a denial of service. A fix for this vulnerability is available. Vulnerability Details CVEID:CVE-2020-4411 DESCRIPTION: The Spectrum Scale 4.2.0.0 throug...

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.

CVE-2021-44852

An issue was discovered in BSRCIO64.sys in Biostar RACING GT Evo 2.1.1905.1700. A low-integrity process can open the driver's device object and issue IOCTLs to read or write to arbitrary physical memory locations or call an arbitrary address, leading to execution of arbitrary code. This is...

CVE-2021-1115

NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer nvlddmkm.sys handler for private IOCTLs, where an attacker with local unprivileged system access may cause a NULL pointer dereference, which may lead to denial of service in a component beyond the vulnerable...

It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information WiFi network traffic. CVE-2020-3702 Alois Wohlschlager discovered that the overlay file system in the Linux kernel did not...

Breaking the NFC chips in tens of millions of smart phones, and a few PoS systems

This second post is a companion to the DEF CON 29 video. Starts at 25:43 here. About a year ago I did some research into adding new capabilities to Samsung’s NFC chips in their smartphones, by bypassing their signature protection and applying code patches. This allowed me to add custom NFC tag...
