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,...

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-2026-98277

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...

windows_tcpip_fuzz

windowstcpipfuzz This is my attempt at fuzzing the tcpip.sys driver in windows via using scapy. This is inspired by this vulnerability here: https://doar-e.github.io/blog/2021/04/15/reverse-engineering-tcpipsys-mechanics-of-a-packet-of-the-death-cve-2021-24086/...

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. A local user with network configuration privileges can trigger this issue by altering the Maximum Transmission Unit MTU, which causes...

kernel: ice: fix double-free of tx_buf skb

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: igc: Fix the PTM cycle trigger logic Writing to clear the “valid” bit of the PTM status while the PTM cycle is triggered results in unreliable PTM operations. To address this issue, clear the PTM “trigger” and status after each P...

Astra Linux – Vulnerability in Linux, Linux 5.10

A vulnerability was discovered in the drivers/usb/gadget/function/rndis.c file within the Linux kernel before version 5.16.10. The RNDIS USB gadget does not include validation for the size of the RNDISMSGSET command. Attackers can obtain sensitive information from the kernel memory...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5: Discarded command completions in internal errors. Fixed the use of “free” after a device enters an internal error state. Avoid calling the completion handler in this case, as the device will flush the command interfa...

kernel: net: mana: Fix TOCTOU double-fetch of hwc_msg_id from DMA buffer

A flaw was found in the Linux kernel's mana network driver. This Time-of-Check to Time-of-Use TOCTOU vulnerability allows a hardware component to modify a message identifier hwcmsgid in Direct Memory Access DMA memory after it has been validated but before it is used. This manipulation bypasses...

CVE-2026-100076

A flaw was found in the Linux kernel's rtl8723bs wireless network driver. When handling wireless management frames under certain error conditions, the driver fails to release allocated transmission frames and buffers back to their memory pools. An attacker within radio range could send unexpected...

CVE-2026-97966

A flaw was found in the Linux kernel's Marvell OCTEON TX2 network driver. When tearing down Hierarchical Token Bucket HTB quality-of-service queues, the driver fails to clear hardware scheduler topology configurations before returning queues to the shared pool. A local user with network...

CVE-2026-97962

A flaw was found in the Linux kernel's mlx5 network driver. The driver fails to hold the required lock when destroying virtual network interface health reporters during device unloading. A local user with administrative privileges could trigger this flaw by unbinding the driver, resulting in a...

CVE-2026-97957

A flaw was found in the Linux kernel's hinic network driver. An attacker with access to send mailbox messages, such as from a guest operating system utilizing a Virtual Function VF, a virtualized network interface, can exploit insufficient validation of message segment lengths. This flaw can caus...

CVE-2026-97953

A flaw was found in the Linux kernel's stmmac network driver. An attacker can cause a Denial of Service DoS by transmitting highly fragmented network packets that use TCP Segmentation Offload TSO. Due to an improper calculation of required transmit descriptors, the driver writes past available...

CVE-2026-102762

The NetX Duo MQTT client leaks the packet carrying a malformed PUBLISH message. Each malformed PUBLISH costs one packet, or one chain of packets, from the network driver's receive pool, and nothing returns it. A peer that can deliver a few dozen such messages exhausts the pool and stops all inbou...

CVE-2026-97603

A flaw was found in the Linux kernel's idpf network driver. This flaw allows a local user with administrative privileges to cause a Denial of Service DoS through a kernel crash. The issue occurs because dynamic interrupt moderation DIM background tasks are not disabled before releasing queue vect...

CVE-2026-97434

A flaw was found in the Linux kernel's dpaa2-switch network driver. During device removal, network packet polling instances NAPI shared across switch ports can be deleted before they are properly disabled. A local user with administrative privileges could trigger this issue during device teardown...

CVE-2026-97411

A flaw was found in the Linux kernel's IBM EMAC network driver. During module removal, the driver unconditionally attempts to disable network polling routines even if they were never enabled or were already stopped. This improper state handling causes the kernel to enter an infinite loop, resulti...
