CVE-2021-21781
An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version 5.11-rc4 seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a...

PPLdump - Dump The Memory Of A PPL With A Userland Exploit
This tool implements a userland exploit that was initially discussed by James Forshaw a.k.a. @tiraniddo - in this blog post - for dumping the memory of any PPL as an administrator. I wrote two blog posts about this tool. The first part is about Protected Processes concepts while the second one...

Qualcom qseecom driver 安全漏洞
Qualcom qseecom driver is a kernel interface from Qualcom. It provides the kernel driver with a bridge between the userland Normal world and the Secure world. A security vulnerability exists in the qseecom driver, which arises from a potentially arbitrary memory corruption when updating a physica...
PlayStation: SMAP bypass
SMAP is a security feature on x86 CPUs, that forbids ring0 from reading/writing to ring3 pages, making it harder to exploit entire classes of vulnerabilities. There is a vulnerability in FreeBSD 12 that allows SMAP to be bypassed by userland. There is a very high probability that it affects the P...
Information disclosure
Trend Micro Antivirus for Mac 2020 Consumer contains an Error Message Information Disclosure vulnerability that if exploited, could allow kernel pointers and debug messages to leak to userland. An attacker must first obtain the ability to execute high-privileged code on the target system in order...

Nintendo: [3DS][StreetPass] Heap Overflow in Swapnote parser leads to userland StreetPass RCE
Affected Systems - System: Nintendo 3DS - Version: = 11.13 - Region: ALL Description When parsing TLRF chunks in message files the application calls memcpy using user provided sizes to copy controlled data over a fixed-size buffer. Thus one can overflow heap chunks which is enough to get code...
Null pointer dereference
In versions 7.1.5-7.1.9, BIG-IP Edge Client Windows Stonewall driver does not sanitize the pointer received from the userland. A local user on the Windows client system can send crafted DeviceIoControl requests to \.\urvpndrv device causing the Windows kernel to crash...
Razer Synapse Service 1.0.0 DLL Injection
Discovered by: Juan Sacco Razer Synapse Service v1.0.0 is prone to a DLL Injection because it fails to properly filter user supplied input and loads a .DLL from %ProgramData% from userland with SYSTEM rights allowing to escalate the priveleges from a regular user to SYSTEM rights. Program: Raze...

Keybase: Keybase client (Windows 10): Write files anywhere in userland using relative path in "download attachement" feature
Summary I've tested this vulnerability on Windows 10, with last keybase client. If a user click on "Download file" during a chat, an attacker can write files anywhere in userland. When downloading a file from a chat, the file should always be written in "Downloads" folder. Proof of concept You ne...
FreeBSD : FreeBSD -- Kernel memory disclosure in freebsd32_ioctl (6b856e00-b30a-11e9-a87f-a4badb2f4699)
Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes. Impact : A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory. Such memo...
FreeBSD : FreeBSD -- Privilege escalation in cd(4) driver (14a3b376-b30a-11e9-a87f-a4badb2f4699)
To implement one particular ioctl, the Linux emulation code used a special interface present in the cd4 driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd4 device t...

CVE-2019-5605
CVE-2019-5605 affects FreeBSD with kernel memory disclosure via the 32-bit ioctl path (freebsd32_ioctl). The root cause is insufficient initialization of memory copied to userland, allowing a local attacker to read small portions of kernel memory, which could contain sensitive data such as file c...
