CVE-2026-64135

A flaw was found in the Linux kernel's pmbus/adm1266 driver. This vulnerability occurs because the adm1266nvmemreadblackbox function uses a small, fixed-size buffer to read data from an I2C Inter-Integrated Circuit device. If the device sends more data than the buffer can hold, it causes a buffer...

CVE-2026-64149

A flaw was found in the Linux kernel's Direct Memory Access DMA mapping subsystem. On ARM64 systems configured with SPARSEMEM a memory management model, the dmamapresource function could incorrectly identify valid memory-mapped input/output MMIO addresses as random access memory RAM. This false...

CVE-2026-64207

A flaw was found in the Linux kernel's DualPI2 Dual-rate PI2 queue discipline. This vulnerability arises from incorrect accounting of Generic Segmentation Offload GSO backlog, where the parent queue such as QFQ - Hierarchical Fair Queueing miscalculates the number of queued packets. This...

CVE-2026-64184

A flaw was found in the Linux kernel's Data Access MONitor DAMON sysfs schemes. The damonsysfsmemcgpathtoid function does not correctly release a cgroup reference, leading to a resource leak. This vulnerability could allow a local attacker to exhaust system resources, potentially causing a denial...

CVE-2026-64187

A flaw was found in the Linux kernel's XFS filesystem log recovery component. A local attacker could exploit this vulnerability by crafting a malicious XFS log. When the system attempts to recover from this log, it triggers a null-pointer dereference, which can lead to a system crash. This result...

CVE-2026-63854

A flaw was found in the Linux kernel's AMDGPU driver, specifically within the Video Core Next VCN version 3.0 encoder and decoder rings. These rings do not support 64-bit user fence writes. A local user could trigger this by attempting to submit commands with 64-bit user fences, which would resul...

CVE-2026-63855

A flaw was found in the Linux kernel's AMDGPU Video Core Next VCN driver. The VCN encoder and decoder rings do not support 64-bit user fence writes. A local attacker could exploit this by submitting commands with unsupported 64-bit user fences, which could lead to system instability or a denial o...

CVE-2026-63848

A flaw was found in the Linux kernel's AMD GPU JPEG driver. This vulnerability occurs because the JPEG rings do not support 64-bit user fence writes. An attacker could exploit this by submitting commands with 64-bit user fences, leading to the rejection of command submissions and potentially a...

CVE-2026-63846

A flaw was found in the Linux kernel's drm/amdgpu/jpeg component, specifically within the JPEG v3.0 ring. This component does not support 64-bit user fence writes. Consequently, any command submissions CS that attempt to use 64-bit user fences will be rejected, leading to a functional limitation ...

CVE-2026-63847

A flaw was found in the Linux kernel's AMD GPU JPEG driver. This issue occurs because the JPEG hardware component does not properly handle certain types of graphics commands, specifically 64-bit user fence writes. An attacker could craft and submit malicious commands, causing the system to reject...

CVE-2026-63843

A flaw was found in the Linux kernel's AMD GPU Graphics Processing Unit JPEG Joint Photographic Experts Group component. This vulnerability arises because the JPEG v4.0.5 ring does not correctly support 64-bit user fence writes. A local attacker could exploit this by submitting commands with 64-b...

CVE-2026-63840

A flaw was found in the Linux kernel's drm/amdgpu/jpeg driver. The JPEG v5.3.0 ring within this driver does not support 64-bit user fence writes. A local user or application attempting to submit commands with 64-bit user fences to the amdgpu JPEG v5.3.0 ring will have these submissions rejected...

CVE-2026-63839

A flaw was found in the Linux kernel's Lenovo WMI Windows Management Instrumentation helpers. The lwmidevevaluateint function was identified to have a memory leak, where allocated memory was not properly released under certain conditions. This could lead to a gradual consumption of system memory,...

CVE-2026-63836

A flaw was found in the Linux kernel. Specifically, within the batman-adv throughput meter, an arithmetic overflow in the batadvtpupdatecwnd function can cause a division by zero. This issue can lead to a kernel panic, resulting in a Denial of Service DoS for the affected system...

CVE-2026-63833

A flaw was found in the Linux kernel's ntfs3 filesystem driver. An unprivileged local user with write access to an ntfs3 mounted filesystem can exploit a vulnerability by directly modifying internal Windows Subsystem for Linux WSL permission metadata. This manipulation allows the user to gain roo...

CVE-2026-63827

A flaw was found in the Linux kernel's AppArmor security module. A use-after-free vulnerability exists in the aareplaceprofiles function due to an issue with reference counting during policy data deduplication. This flaw occurs when the system attempts to access memory that has already been freed...

CVE-2026-63825

A flaw was found in the Linux kernel. When the GCOV instrumentation, which helps analyze code coverage, processes data concurrently across multiple central processing units CPUs, it can lead to inconsistent counter values. This inconsistency can cause out-of-bounds memory writes within the...

CVE-2026-63819

A flaw was found in the Linux kernel's f2fs Flash-Friendly File System component. A local attacker could create a specially crafted or corrupted f2fs filesystem that, when mounted and operated upon, would trigger a sanity check failure during filesystem truncation. This issue leads to a kernel...
