Implementing Homomorphic Encryption-Based Logic Locking in System-On-Chip Designs

This study presents a logic locking scheme based on the binary Ring Learning With Errors algorithm, implemented in a RISC-V System-on-Chip design. Unlike traditional logic locking methods that require providing users with raw locking parameters, the proposed approach secures critical logic paths ...

FreeBSD Security Advisory - FreeBSD-SA-26:50.kqueue

FreeBSD Security Advisory - While the kernel was copying knotes during fork, a knote with a timer-based filter could fire and be enqueued on the kqueue's active list before the copy was complete. The copy routine did not account for this and could enqueue the new knote a second time, corrupting t...

Linux Distros Unpatched Vulnerability : CVE-2026-62430

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the...

The vulnerability of the amdgpu_userq_fence_driver_process() function in the drivers/gpu/drm/amd/amdgpu/amdgpu_userq_fence.c source file of the Direct Rendering Infrastructure (DRI) driver for AMD GPU cores in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the amdgpuuserqfencedriverprocess function in the drivers/gpu/drm/amd/amdgpu/amdgpuuserqfence.c source code of the Direct Rendering Infrastructure DRI driver for AMD GPU cores in the Linux operating system is related to the occurrence of mutual locking. Exploiting this...

The vulnerability of the bpf_local_storage_update() function in the kernel/bpf/bpf_local_storage.c module allows a hacker to cause a service failure.

The vulnerability of the bpflocalstorageupdate function in the kernel/bpf/bpflocalstorage.c file, which is part of the Linux kernel’s BPF support for operating system functions, relates to improper locking of resources. Exploiting this vulnerability could allow an attacker to cause a service...

CVE-2026-62432

The EVTCHNOPexpandarray hypercall checks for whether FIFO event channels are enabled, but without holding the correct lock. It can race with EVTCHNOPreset, resulting in dereferencing a NULL pointer...

CVE-2026-62430

Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the index didn't take the necessary locking to avoid concurrent changes. As a result, a guest could change the index after it being checked,...

CVE-2026-62427

This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE. To manage the system, sysctl and platform operations are used by the control domain or a possible Xenstore domain. Some of these operations may not be executed in paralle...

CVE-2026-62430

Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the index didn't take the necessary locking to avoid concurrent changes. As a result, a guest could change the index after it being checked,...

CVE-2026-62432

The Xen hypervisor is vulnerable to a race condition in the EVTCHNOP_expand_array hypercall. The hypercall fails to hold the correct lock when checking if FIFO event channels are enabled, which can cause a race with EVTCHNOP_reset and lead to a NULL pointer dereference . This issue may result in ...

CVE-2026-62430

The Xen hypervisor is vulnerable to an out-of-bounds read in vRTC emulation (x86) due to a missing lock when accessing CMOS memory contents via an indirect IO port pair. A guest could change the index after it was checked, leading to the out-of-bounds access. This issue is addressed in XSA-503 an...
