CVE-2025-62864

AmpereOne Firmware Out-of-Bounds Write Vulnerability.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

An out-of-bounds write vulnerability in AmpereOne devices can occur through a malformed SMC call to the UEFI-MM MMCommunicate service. This could allow an attacker to corrupt data within the UEFI-MM Secure Partition, potentially impacting system integrity and confidentiality.

CVE advisoryCRITICAL

CVE-2025-50401

Mercury D196G Buffer Overflow Vulnerability in Password Parameter.

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

Mercury D196G devices contain a critical buffer overflow vulnerability in their password handling function that can be exploited remotely without authentication. Successful exploitation could allow an attacker to gain unauthorized access and control over the device, potentially impacting its functionality and the broad

CVE advisoryCRITICAL

CVE-2025-50398

Mercury D196G Firmware Buffer Overflow in fac_password Function.

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

A critical buffer overflow vulnerability exists in Mercury D196G firmware affecting the `fac_password` parameter, potentially allowing remote code execution by unauthenticated attackers. This could lead to device compromise and impact confidentiality, integrity, and availability. It is important to determine if this te

CVE-2025-68301

Linux Kernel Network Driver Fragment Overflow Leads to Kernel Panic

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

A vulnerability in the Linux kernel's network driver can cause a system crash when handling certain network packets. This is triggered by specially crafted traffic and affects specific network hardware, potentially leading to denial of service and impacting kernel stability.

CVE advisoryCRITICAL

CVE-2025-68285

Linux Kernel libceph Use-After-Free Vulnerability in have_mon_and_osd_map

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

A use-after-free vulnerability exists in the Linux kernel's libceph component, specifically within the `have_mon_and_osd_map()` function. This flaw can arise from a race condition during session establishment when the client rapidly receives new network maps, potentially leading to kernel memory corruption and system i
