CVE-2026-46142

A flaw was found in the Linux kernel's libwx network driver. When a Virtual Function VF is initialized, it attempts to read a Physical Function PF restricted register, WXCFGPORTST. This illegal register access can lead to a system hang, resulting in a Denial of Service DoS...

CVE-2026-46147

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for ARM64 architectures. During the vCPU initialization process, a pin leak can occur, leading to a permanent loss of references to host vCPU and SVE state pages. Additionally, a concurrent process might observe a partially...

CVE-2026-49238

An issue was discovered in Canonical Multipass before version 1.16.3. The host-side SFTP server component sshfsserver, which executes with root privileges on the host, contains a path containment bypass vulnerability within its validatepath function in src/sshfsmount/sftpserver.cpp. The function...

CVE-2026-46207

A flaw was found in the Linux kernel's vsock/virtio component. When processing non-linear data buffers for the vsockmon tap device, the system did not correctly initialize the payload. This oversight could lead to uninitialized data being copied to the monitoring interface, potentially resulting ...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...
