PT-2026-71098

Docker Sandboxes sbx applies the read-only intent of a runtime host mount to the in-guest container bind only: the underlying virtio-fs host-edge grant is added to the sandbox's policy-share allowlist with no access mode. The directory stays writable at its shared-export path, so unprivileged cod...

CVE-2026-68255

A flaw was found in the kernel. A malicious virtio-gpu backend can exploit an out-of-bounds read vulnerability in the drm/virtio component of the Linux kernel. By manipulating the Extended Display Identification Data EDID block index and advertising a large size, the backend can read beyond the...

CVE-2026-68411

A flaw was found in the Linux kernel's mac80211hwsim component. A malicious backend device could report an oversized receive length to the hwsimvirtiorxwork function. This could cause the system to write past the end of a buffer, leading to a kernel panic and a denial of service DoS for the guest...

CVE-2026-68411

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: clamp virtio RX length before skbput hwsimvirtiorxwork passes the virtqueue used-ring length reported by the device straight to skbput on a fixed-size receive skb. A backend reporting a length larger than the...

CVE-2026-68411

The CVE affects the Linux kernel’s wifi/mac80211_hwsim path. In hwsim_virtio_rx_work(), the virtqueue used-ring length reported by the device could be passed directly to skb_put() on a fixed-size receive skb, allowing skb_over_panic() and a host-triggerable guest panic (DoS) when length exceeds t...

CVE-2026-68255

Summary: CVE-2026-68255 affects the Linux kernel DRM/virtio EDID handling. The function virtio_get_edid_block() validates reads only against the device-supplied resp->size, not against the fixed-size resp->edid array. An attacker-controlled virtio-gpu backend can advertise a large size with...
