CVE-2026-64524

The CVE-2026-64524 issue affects the Linux kernel's DRM Hyper-V driver. A SYNTHVID_RESOLUTION_RESPONSE with resolution_count > 64 could bypass the bound check on the supported_resolution array, potentially leading to out-of-bounds behavior during parsing. The fix binds resolution_count to the ...

CVE-2026-64504

Summary: CVE-2026-64504 affects the Linux kernel IIO driver for the BMC150 accelerometer. The flush path in __bmc150_accel_fifo_flush() could transfer up to count samples from the device FIFO, with count derived from FIFO_STATUS masked to 7 bits (0–127). The on-stack buffer can overflow if a devi...

CVE-2026-64490 ALSA: virtio: Validate control metadata from the device

In the Linux kernel, the following vulnerability has been resolved: ALSA: virtio: Validate control metadata from the device virtio-snd control handling trusts the device-provided control type and value count returned by the device. That metadata is then used directly to index gv2atypemap in...

CVE-2026-64490

CVE-2026-64490 affects the Linux kernel ALSA virtio sound driver. The vulnerability arises when virtio-snd control metadata provided by a device (control type and value count) is trusted without validation, allowing out-of-bounds access in virtsnd_kctl_info(), virtsnd_kctl_get(), and virtsnd_kctl...
