CVE-2026-64582

A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...

Linux Distros Unpatched Vulnerability : CVE-2026-64590

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - dma-buf/udmabuf: skip redundant cpu sync to fix cacheline EEXIST warning When CONFIGDMAAPIDEBUGSG is enabled, importing a udmabuf into a DRM driver e.g. amdgpu...

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-2026-63252

In Eclipse Milo versions 0.6.0 through 1.1.4, UASC server transport handlers fail to release retained partial message chunks when a channel disconnects, allowing a remote unauthenticated client to exhaust pooled direct memory by repeatedly sending incomplete chunks and disconnecting, potentially...

Uncontrolled Resource Consumption (Denial Of Service)

Netty is vulnerable to Uncontrolled Resource Consumption Denial of Service. The vulnerability is due to improper handling of the HAProxy protocol version byte in the HAProxyMessageDecoder, where a signed Java byte is widened to an int without masking, causing a crafted 0xFF version byte to be...

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

Summary A remote, unauthenticated peer can leak one direct ByteBuf per HTTP/2 DATA frame in applications that enable HTTP/2 content decompression via DelegatingDecompressorFrameListener. When a DATA frame is processed for a stream whose decompressor has already been closed,...

GHSA-93WV-JW9V-4972 Netty: HTTP/2 decompression leaks ByteBuf reference count when the decompressor channel is already closed (Direct memory leak / OOM DoS)

CVE-2026-64280

A flaw was found in the Linux kernel's dfl-afu FPGA driver. A local user could exploit this vulnerability by providing an excessively large length value during Direct Memory Access DMA mapping operations. The system incorrectly truncates this value, leading to memory corruption. This could allow ...

CVE-2026-64337

A flaw was found in the Linux kernel's USB mtu3 gadget driver. When the mtu3gadgetqueue function encounters a failure during the preparation of a USB transfer, the associated Direct Memory Access DMA mapping is not properly released. This leaves the DMA mapping active, which can lead to a resourc...

CVE-2026-64269

A flaw was found in the Linux kernel's RDMA Remote Direct Memory Access rtrs-srv module. A remote attacker can exploit this vulnerability by sending a crafted RDMA-Write length during an RTRS READ operation that exceeds the intended buffer size. This out-of-bounds read can lead to information...

CVE-2026-64485

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA compress module. The sndcomprtasknew function, responsible for creating driver tasks, does not properly handle errors during the validation of Direct Memory Access DMA buffers or file descriptor reservation. This...

UBUNTU-CVE-2026-64234

In the Linux kernel, the following vulnerability has been resolved: tty: serial: pchuart: add check for dmaalloccoherent Add a check for dmaalloccoherent failure to prevent a potential NULL pointer dereference in dmahandlerx. Properly release DMA channels and the PCI device reference using a goto...

UBUNTU-CVE-2026-64269

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-srv: Bound RDMA-Write length to chunk size in rdmawritesg When the server answers an RTRS READ, rdmawritesg builds the source scatter/gather entry for the IBWRRDMAWRITE that returns data to the peer. Its length is taken...

CVE-2026-64465 usb: xhci: Fix sleep in atomic context in xhci_free_streams()

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Fix sleep in atomic context in xhcifreestreams When a USB device with active stream endpoints is disconnected, xhcifreestreams is called from the hubevent workqueue to free the stream resources. It calls...

CVE-2026-64337

CVE-2026-64337 affects the Linux kernel's USB MTU3 gadget driver . The function mtu3_gadget_queue() maps the request DMA before checking whether the QMU GPD ring can accept another transfer. When mtu3_prepare_transfer() fails, the request is returned with -EAGAIN but the DMA mapping is never unma...
