etherleak-checker

Etherleak Vulnerability Checker This Python script helps to detect the Etherleak CVE-2003-0001 vulnerability on a target host by analyzing the padding data in network packets. The script uses Scapy to send various types of requests ICMP, ARP, or TCP and checks if the responses contain any padding...

CVE-2026-98492

A flaw was found in the Linux kernel's Cadence MACB network driver. During network buffer allocation, the driver's error-handling routines fail to properly release allocated Direct Memory Access DMA memory buffers when a failure occurs. A local user could trigger these error conditions during...

CVE-2026-98498

A flaw was found in the Linux kernel's mlx5 network driver. When handling shared connection tracking counters, the driver fails to properly release an entry's reference count if the associated counter is in the process of being released. This reference count leak prevents the reverse entry from...

CVE-2026-98494

A flaw was found in the Linux kernel's atl1 network driver. During a PCIe link or hardware reset, the network adapter can return an out-of-range status value that the driver fails to validate properly. This condition can trap the driver in an infinite loop, resulting in a kernel soft lockup and...

CVE-2026-98497

A flaw was found in the Linux kernel's mlx5 network driver. When configuring IPv6 IPsec Internet Protocol Security rules with differing source and destination prefix lengths, the driver inadvertently swaps the source and destination address masks installed into hardware flow tables. This incorrec...

CVE-2026-98489

A flaw was found in the Linux kernel's atl1c network driver. When an interface experiences a link reset or link flapping, the hardware can return an out-of-range descriptor value that the driver fails to validate. An adjacent entity capable of triggering network link state changes can exploit thi...

CVE-2026-98488

A flaw was found in the Linux kernel's Atheros L1E Gigabit Ethernet atl1e network driver. While the network interface hardware is resetting, it can report an unexpected out-of-range status value during transmit packet processing. Because the driver does not properly validate this value, it enters...

CVE-2026-98711

A flaw was found in the Linux kernel's cw1200 wireless network driver. During data transmission, the driver pads transfer sizes to meet hardware alignment requirements without reserving sufficient space in the frame buffer. This causes the driver to read beyond the buffer boundaries and transmit...

CVE-2026-98585

A flaw was found in the Linux kernel's fbnic network driver. A local user with administrative privileges could trigger a denial of service DoS and crash the system by configuring a network ring buffer size of zero. Because the driver fails to validate the input before executing a rounding...

CVE-2026-98571

A flaw was found in the Linux kernel's stmmac network driver. This vulnerability can lead to a Denial of Service DoS or memory corruption when processing incoming network traffic under resource constraints. When the driver fails to allocate a network packet buffer, it recycles the underlying memo...

CVE-2026-98562

A flaw was found in the Linux kernel's Wangxun network driver library libwx. This vulnerability allows a local user to cause a Denial of Service DoS through memory corruption. A race condition in the Precision Time Protocol PTP transmit timestamp handling fails to properly synchronize packet...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-46110)

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Prevent NULL deref when RX memory exhausted The CPU receives frames from the MAC through conventional DMA: the CPU allocates buffers for the MAC, then the MAC fills them and returns ownership to the CPU. For each...

kernel: ixgbevf: fix use-after-free in VEPA multicast source pruning

A flaw was found in the Linux kernel's ixgbevf network driver. This vulnerability, a use-after-free, occurs when the driver attempts to process network packets for a specific multicast workaround. An attacker could potentially exploit this by sending specially crafted network traffic, which may...

Microsoft MANA Network Driver Kernel Privilege Escalation

The vulnerability of the Microsoft MANA Network Driver for Linux operating systems is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow attackers to increase their privileges...

CVE-2026-90082

A flaw was found in the mana network driver within the Linux kernel. This vulnerability occurs because the driver incorrectly calculates the number of Message Signaled Interrupts MSI-X vectors, leading to an out-of-bounds write. A local attacker, by operating a specially crafted virtual machine,...

CVE-2026-98277

A flaw was found in the Linux kernel's fbnic network driver. When transmitting a burst of network packets, the driver defers notifying the network hardware until the final packet in the batch is processed. If that concluding packet is dropped due to an error, such as memory handling or direct...

CVE-2026-98272

A flaw was found in the Linux kernel's Marvell mvpp2 network driver. This vulnerability can lead to a Denial of Service DoS due to an out-of-bounds memory access.
