The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: ethernet: mtkppe: avoid NULL deref when gmac0 is disabled If the gmac0 is disabled, the precheck for a valid ingress device will cause a NULL pointer deref...

Reflecthernet: Exfiltrating 100BASE-TX Ethernet Traffic Using a Retroreflector Hardware Trojan

Electromagnetic eavesdropping is a well-established attack vector for remotely monitoring a target activity, most notably displays, over considerable ranges. Other targets have been considered resistant to such attacks or do not exhibit sufficient electromagnetic leakage for practical exploitatio...

CVE-2026-31724

A flaw was found in the Linux kernel's USB gadget Ethernet Emulation Model EEM function. This issue occurs when a USB gadget function disconnects, causing the related network device to not be properly removed. As a result, invalid links remain in the system's file system, known as dangling symbol...

CVE-2026-31752

In the Linux kernel, the following vulnerability has been resolved: bridge: brndsend: validate ND option lengths brndsend walks ND options according to option-provided lengths. A malformed option can make the parser advance beyond the computed option span or use a too-short source LLADDR option...

CVE-2026-31738

In the Linux kernel, the following vulnerability has been resolved: vxlan: validate ND option lengths in vxlannacreate vxlannacreate walks ND options according to option-provided lengths.

CVE-2026-43039

In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg-prueth: fix missing data copy and wrong recycle in ZC RX dispatch emacdispatchskbzc allocates a new skb via napiallocskb but never copies the packet data from the XDP buffer into it. The skb is passed up the stack...

EUVD-2026-26565

In the Linux kernel, the following vulnerability has been resolved: bridge: brndsend: validate ND option lengths brndsend walks ND options according to option-provided lengths. A malformed option can make the parser advance beyond the computed option span or use a too-short source LLADDR option...

CVE-2026-31752

CVE-2026-31752 affects the Linux kernel bridge/networking path: br_nd_send validates IPv6 neighbor discovery options, and a malformed ND option could cause the parser to read beyond the intended option span or read an LLADDR payload that is too short. The issue is mitigated by option-length check...

EUVD-2026-26551

In the Linux kernel, the following vulnerability has been resolved: vxlan: validate ND option lengths in vxlannacreate vxlannacreate walks ND options according to option-provided lengths. A malformed option can make the parser advance beyond the computed option span or use a too-short source LLAD...

CVE-2026-31738

CVE-2026-31738 concerns the Linux kernel vxlan code (vxlan_na_create) where ND option lengths are not properly validated. The flaw can cause the parser to advance beyond the option span or read an undersized LLADDR payload, enabling source address reading only when the option is large enough; imp...
