CVE-2026-18711

The CVE-2026-18711 entry concerns MongoDB Server's query execution engine. It describes a use-after-free condition triggered by certain queries against time-series collections, where an authenticated user with read and write privileges can cause an internal reference to be used after memory has b...

CVE-2026-68172

A flaw was found in the Linux kernel, specifically within the hugeptepget helper function for the arm64 architecture. When this function is provided with an unaligned virtual address, it can incorrectly process Page Table Entries PTEs. This can lead to the kernel dereferencing invalid memory...

CVE-2026-68242

A flaw was found in the Linux kernel's graphics subsystem specifically drm/i915/gt. This vulnerability arises from an improper handling of memory allocation failures during graphics engine scheduling, which can lead to a null pointer dereference. A local attacker could exploit this issue to trigg...

CVE-2026-68218

A flaw was found in the dm1105 PCI driver of the Linux kernel. This issue arises from the driver's failure to properly deallocate resources, specifically a workqueue, when the device is removed. This oversight can lead to a memory leak, which a local attacker could potentially exploit to cause a...

CVE-2026-68164

A flaw was found in the Linux kernel's DAMON Data Access MONitor subsystem. The damonsetregions function, responsible for setting memory monitoring regions, incorrectly processes unsorted or overlapping input ranges due to a missing validation check. This can lead to unexpected behavior in DAMON...

CVE-2026-68274

A flaw was found in the Linux kernel's drm/xe/guc component. An incorrect calculation of the steered register list allocation size can lead to a buffer overflow. This allows an attacker to write past the allocated buffer, corrupting adjacent memory objects. This memory corruption can result in...

CVE-2026-68256

A flaw was found in the drm/amd/display component of the Linux kernel. This issue occurs in the detectlinkandlocalsink function, where a prevsink reference is not properly released if the DisplayPort DP alt mode timeout path returns false. This missing cleanup can lead to a memory leak, potential...

CVE-2026-68183

A flaw was found in the stratix10-svc firmware component of the Linux kernel. This vulnerability involves memory leaks when memory allocation fails and list corruption due to incorrect memory management and an erroneous list deletion operation. These issues could lead to system instability or a...

CVE-2026-68262

A flaw was found in the Linux kernel. The drm/imagination component's pvrsetuobjarray function mishandles the user array stride during copies of kernel objects to a userspace array. This error causes incorrect memory access, leading to memory corruption where data is written to unintended...

CVE-2026-68248

A flaw was found in the Linux kernel's drm/i915 graphics driver. This vulnerability occurs when the system experiences an Out-Of-Memory OOM condition during a specific memory allocation. An attacker could potentially trigger this condition, leading to an improper return value and causing a system...

CVE-2026-68258

A flaw was found in the drm/amdkfd component of the Linux kernel. This vulnerability allows a local attacker to provide out-of-bounds values in the private data during a kfd CRIU restore operation. This improper input validation could lead to a memory safety issue, potentially resulting in a deni...

CVE-2026-68163

A flaw was found in the Linux kernel's memory management subsystem. Incorrect handling of device-private Page Middle Directory PMD entries can lead to memory corruption. Specifically, when pagevmamappedwalk encounters these entries, it can misinterpret them as migration entries, resulting in memo...

CVE-2026-68232

A flaw was found in the Linux kernel's drm/gpusvm component. When the kvmallocarray function fails within drmgpusvmrangeevict, a previously acquired memory management MM reference is not properly released. This oversight leads to a reference leak, which can result in resource exhaustion and a...

CVE-2026-68271

A flaw was found in the Linux kernel's drm/nouveau module. An issue with the error cleanup order in ucopy functions can lead to incorrect memory deallocation. This can result in a system crash, also known as a kernel oops, or a memory leak, potentially causing a denial of service...

CVE-2026-68221

A flaw was found in the Linux kernel's Nuvoton NPCM video driver. The npcmvideoprobe function allocates memory that is not properly freed on error paths or during device removal, leading to memory leaks. Additionally, when npcmvideosetupvideo fails, associated reserved memory is not released. The...
