CVE-2026-56819 Netty: HTTP/2 decompression leaks ByteBuf reference count when the decompressor channel is already closed (Direct memory leak / OOM DoS)

Netty is a network application framework for development of protocol servers and clients. In versions 4.2.0.Final through 4.2.15.Final and 4.1.0.Final through 4.1.135.Final, a remote unauthenticated peer can leak one direct ByteBuf per HTTP/2 DATA frame in applications that enable HTTP/2 content...

CVE-2026-63883

A flaw was found in the Linux kernel's qcomgeni serial driver. A race condition can occur when the uartflushbuffer function executes before the Direct Memory Access DMA completion interrupt is processed. This timing issue can lead to a kernel First-In, First-Out kfifo buffer underflow...

CVE-2026-63859

A flaw was found in the Linux kernel's airoha network driver. The airohaqdmacleanuptxqueue routine, responsible for cleaning up transmit queues, was missing critical steps. This omission could lead to improper resetting of Direct Memory Access DMA transmit descriptors and incorrect notification t...

CVE-2026-63910

A flaw was found in the Linux kernel's dma-buf Direct Memory Access buffer subsystem. A race condition in the dmabuffd tracepoint can lead to a Use-After-Free UAF vulnerability. A local attacker could exploit this by closing a file descriptor fd prematurely, causing the dmabuf to be freed while t...

CVE-2026-63929

A flaw was found in the Linux kernel's Industrial I/O iio buffer component. The iiobufferenqueuedmabuf function, responsible for managing Direct Memory Access DMA buffers, fails to properly release a memory reference. This oversight results in a continuous memory leak, where small blocks of memor...

CVE-2026-64019

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express PCI Peripheral Component Interconnect driver. This vulnerability occurs due to a leak in the Direct Memory Access DMA mapping during data setup operations. Specifically, the system fails to properly unmap DMA resources when...

SUSE CVE-2026-63883

In the Linux kernel, the following vulnerability has been resolved: serial: qcomgeni: fix kfifo underflow when flush precedes DMA completion IRQ When uartflushbuffer runs before the DMA completion IRQ is delivered, the following race can occur all steps serialized by uartportlock: 1. DMA starts:...

SUSE CVE-2026-64042

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Check BAR resources before exporting a DMABUF A DMABUF exports access to BAR resources and, although they are requested at startup time, we need to ensure they really were reserved before exporting. Otherwise, it's...

SUSE CVE-2026-64170

In the Linux kernel, the following vulnerability has been resolved: spi: qup: fix error pointer deref after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to the clear the DMA channel pointers on setup failure to avoid dereferencing an error pointer...

CVE-2026-64151

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit page table driver. This vulnerability involves a missing check for the system's fundamental memory page size PAGESIZE within the pgsizebitmap data structure. While an IOMMU configuration with this missing check would...

CVE-2026-64169

A flaw was found in the Linux kernel's spi: ep93xx driver. This vulnerability occurs when the driver fails to properly clear Direct Memory Access DMA channel pointers after a DMA setup failure during probe. An attacker could potentially trigger a system crash, leading to a Denial of Service DoS...

CVE-2026-64145

A flaw was found in the Linux kernel's wilc1000 Wi-Fi driver. This vulnerability occurs during the firmware download process when the system fails to properly acquire the bus. An error in the code's cleanup path causes a Direct Memory Access DMA buffer to not be released, resulting in a memory...

netty-codec-redis: Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by repeatedly closing Redis pipeline connections before a Redis array aggregate completes. This leads to a permanent leak of direct-memory buffers, which prevents memory chunks from being returned to the share...

CVE-2026-64170

A flaw was found in the Linux kernel's Serial Peripheral Interface SPI Qualcomm Universal Peripheral QUP driver. When the Direct Memory Access DMA setup fails during the driver's initialization, the driver attempts to fall back to Programmed Input/Output PIO mode. However, it fails to properly...
