CVE-2026-74743

A flaw was found in the Linux kernel's macvlan component. The macvlan component incorrectly initializes network packet buffer skb headroom and tailroom values, failing to inherit them from the underlying network device. This can occur when the underlying device requires additional space for heade...

New SLEEPWALKER Backdoor Waits for One Crafted Packet, Then Runs Its Own Bytecode

An independent malware researcher has documented a previously unreported Windows backdoor, dubbed SLEEPWALKER , that stays inert in memory until a specifically crafted network packet reaches the machine and then runs commands written in a 23-instruction language of its own design. The sample is a...

EUVD-2026-62876

IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 Power Systems Firmware is affected by a vulnerability in partition firmware during network boot. An unauthenticated attacker on the same network as a partition undergoing...

CVE-2026-72036

A flaw was found in the Linux kernel's schmultiq component, which handles network packet scheduling. This vulnerability occurs when a non-work-conserving child queue is improperly handled after a packet has been temporarily stored. This can lead to a desynchronization of network packet queues and...

PCP: PCP: Denial of Service due to signed integer overflow

A signed integer overflow in the PCP pmGetPDU function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service DoS for subsequent packet reads...

CVE-2026-64545

A flaw was found in the Linux kernel. The xdpmasterredirect function, which handles network packet redirection, does not properly check for a null pointer. This oversight allows a local attacker to trigger a null pointer dereference by sending a specially crafted XDP eXpress Data Path packet duri...
