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-2026-64485

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-2026-64269

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-2026-64337

CVE-2026-64337 (Linux kernel): usb mtu3 flaw where mtu3_gadget_queue() maps the request before verifying QMU GPD space, causing a DMA mapping to remain active if mtu3_prepare_transfer() fails and the request isn’t linked. The fix unmaps the DMA on the failed queue path before returning. Documents...
