UBUNTU-CVE-2026-64483

In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire: isight: bound the sample count to the packet payload isightpacket takes the frame count from the device iso packet and checks it only against the device claimed iso length. count = be32tocpupayload-samplecount; if...

EUVD-2026-48871

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Initialize epfile-in early to fix endpoint direction checks When parsing endpoint descriptors, ffsdatagotdescs generates the epsaddrmap which contains the endpoint direction. However, epfile-in was previously on...

CVE-2026-64304

In the Linux kernel, CVE-2026-64304 affects the crypto qat driver: the RSA CRT component handling in qat_rsa_setkey_crt() can write out of bounds when a CRT component exceeds the allocated half-key buffer, causing memory corruption. The root cause is that the generic RSA key parser bounds compone...

CVE-2026-63894

A flaw was found in the Linux kernel's FunctionFS ffs component. A race condition exists where a Direct Memory Access Buffer DMABUF cancel operation can occur concurrently with a request completion, leading to a use-after-free vulnerability. This allows a privileged local attacker, such as a...

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-2026-64042

A flaw was found in the Linux kernel's vfio/pci subsystem. This vulnerability occurs because the Direct Memory Access Buffer DMABUF export mechanism does not adequately verify if Base Address Register BAR resources are properly reserved before allowing access. A local attacker could exploit this ...

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...

CVE-2026-63910

In the Linux kernel, the following vulnerability has been resolved: dma-buf: fix UAF in dmabuffd tracepoint Once FDADD returns, the fd is live in the file descriptor table and a thread sharing that table can close it before DMABUFTRACE runs. The close drops the last reference, fput frees the...

CVE-2026-64145

In the Linux kernel WiFi driver wilc1000, a memory-leak in firmware download was fixed: wilc_wlan_firmware_download() allocates dma_buffer with kmalloc() and, on early failure after the first acquire_bus(), could return without freeing the buffer. The code now uses a goto fail cleanup path to ens...
