CVE-2026-93830

A flaw was found in the Linux kernel's stmmac network driver. An attacker can cause a Denial of Service DoS by sending high volumes of network traffic to an affected system. Under heavy packet load, the network controller exhausts its receive buffers and continuously fires hardware interrupts...

CVE-2026-97569

A flaw was found in the Linux kernel's Broadcom NetXtreme-E bnxten network driver. An attacker can cause a Denial of Service DoS by sending a burst of network traffic followed by a large UDP Segmentation Offload USO packet. When operating with small transmit ring configurations, the driver...

CVE-2026-102762: Missing Release of Memory after Effective Lifetime

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-2026-98028

A flaw was found in the Linux kernel's Netronome Flow Processor NFP network driver. When replacing an existing flow steering rule fails during hardware reprogramming, the driver fails to remove the old rule from its internal list, creating an inconsistency with the active rule counter. A local us...

CVE-2026-98016

A flaw was found in the Linux kernel's Mellanox network driver mlx5e. A race condition occurs during the concurrent teardown of traffic control TC sample rules sharing the same context, causing the system to reference memory after it has already been freed. A local user with network administrativ...

CVE-2026-98014

A flaw was found in the Linux kernel's Mellanox network driver mlx5. This vulnerability allows a local privileged user to cause a Denial of Service DoS through a system crash. During hardware reset or error recovery procedures, improper cleanup when disabling a virtual network port leaves stale...

CVE-2026-93279

A flaw was found in the Linux kernel's Octeon network driver. During network device shutdown or driver removal, a pending cleanup task may execute after associated network device structures have already been freed from memory. A local user could exploit this race condition during device teardown ...

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-2026-93278

A flaw was found in the Linux kernel's Octeon network driver. During interface shutdown, the driver deletes the packet polling mechanism without properly disabling it first, allowing active polling routines to continue running after interrupt handlers are released. A local attacker could exploit...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sfc: Fixed the null pointer dereference in efxhardstartxmit. Trying to access the channel from the txqueue variable is incorrect because we can only be in this situation if txqueue is NULL. Therefore, we should not dereference it...
