CVE-2026-63958

A flaw was found in the Linux kernel's USB Type-C subsystem. This vulnerability allows a malicious or buggy Power Delivery Microcontroller PPM, such as embedded controller EC firmware or an I2C-attached Universal Serial Bus USB Type-C Connector System Interface UCSI controller, to provide an...

CVE-2026-63938

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV feature. When processing Page State Change PSC requests, the system does not properly validate the PSC buffer against the effective size of the scratch area. This can occur if a guest...

CVE-2026-63927

A flaw was found in the Linux kernel, specifically within the dwc2 USB driver. This vulnerability, known as a use-after-free, occurs when the system attempts to access memory that has already been released. This happens because a USB Request Block urb is incorrectly accessed after it has been...

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-2026-64000

A flaw was found in the Linux kernel's High-availability Seamless Redundancy HSR module. This vulnerability allows an attacker to cause an out-of-bounds OOB access by sending a specially crafted, truncated supervision frame. The issue arises because the system does not ensure the entire TLV...

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-2026-64168

In the Linux kernel, the following vulnerability has been resolved: spi: sprd: fix error pointer deref after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to check the dma.enabled flag before trying to release the DMA channels also on late probe...

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-2026-64608

Apache Fory: C++ implementation suffers a heap type confusion and out-of-bounds read/write during deserialization in compatible mode. Inconsistent schemas between declared field types and data can trigger memory access issues. Affected: Apache Fory C++ from 0.14.0 up to but not including 1.4.0. R...
