CVE-2026-87041

The RTIO submission-queue verifier rtio_vrfy_sqe() in subsys/rtio/rtio_syscalls.c (prior to v4.3.0) contains an inverted memory-permission check. Because the verifier incorrectly used bitwise AND (&=) to accumulate results from K_SYSCALL_MEMORY(), it accepted pointers that were not accessible to ...

CVE-2026-99016 riscv: futex: untag the user pointer before the atomic access

In the Linux kernel, the following vulnerability has been resolved: riscv: futex: untag the user pointer before the atomic access accessok checks untaggedaddruaddr, but archfutexatomicopinuser and futexatomiccmpxchginatomic hand the raw uaddr to the inline asm amoswap/amoadd/.../lr.w+sc.w through...

CVE-2026-19676 PECI transfer syscall verifier does not validate embedded user buffer pointers, allowing arbitrary kernel memory read/write from user mode

The user-mode verifier for the pecitransfer system call, zvrfypecitransfer in drivers/peci/pecihandlers.c, checked only the device object permission and copied the caller-supplied struct pecimsg with kusermodefromcopy. That copy validates the outer structure only; the buf pointers and len values...

CVE-2026-19676

The peci_transfer() system call in the Zephyr RTOS (specifically within drivers/peci/peci_handlers.c ) fails to properly validate embedded buffer pointers and length values in the peci_msg structure. While the verifier checks outer structure permissions, it allows caller-controlled pointers in th...

CVE-2025-62525: Improper Input Validation

OpenWrt Project is a Linux operating system targeting embedded devices. Prior to version 24.10.4, local users could read and write arbitrary kernel memory using the ioctls of the ltq-ptm driver which is used to drive the datapath of the DSL line. This only effects the lantiq target supporting...

Design/Logic Flaw

The timercreate syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigevnotify field, which leads to out-of-bounds access in the showtimer function called when /proc/$PID/timers is read. This allows userspace applications ...

CVE-2017-18344

The timercreate syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigevnotify field, which leads to out-of-bounds access in the showtimer function called when /proc/$PID/timers is read. This allows userspace applications ...

The NVIDIA GPU driver for FreeBSD R352 before 352.09, 346 before 346.72, R349 before 349.16, R343 before 343.36, R340 before 340.76, R337 before 337.25, R334 before 334.21, R331 before 331.113, and R304 before 304.125 allows local users with certain permissions to read or write arbitrary kernel...

CVE-2014-8823: Undefined Security Weakness

The IOUSBControllerUserClient::ReadRegister function in the IOUSB controller in IOUSBFamily in Apple OS X before 10.10.2 allows local users to read data from arbitrary kernel-memory locations by leveraging root access and providing a crafted first argument...

CVE-2013-6282

The 1 getuser and 2 putuser API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against...

CVE-2013-1261: Concurrent Execution using Shared Resource with Improper Synchronization

Race condition in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows local users to gain privileges, and consequently read the contents of arbitrary kerne...

CVE-2010-0415

The dopagesmove function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service OOPS, and possibly have unspecified other impact by specifying a node that is not part of the...

CVE-2008-0010: Improper Input Validation

The copyfromusermmapsem function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which allow local users to read from arbitrary kernel memory locations...

CVE-2005-4783: Undefined Security Weakness

kernfsxread in kernfsvnops.c in NetBSD before 20050831 does not check for a negative offset when reading the message buffer, which allows local users to read arbitrary kernel memory...

CVE-2006-0145: Undefined Security Weakness

The kernfsxread function in kernfs in NetBSD 1.6 through 2.1, and OpenBSD 3.8, does not properly validate file offsets against negative 32-bit values that occur as a result of truncation, which allows local users to read arbitrary kernel memory and gain privileges via the lseek system call...
