CVE-2026-64125

A flaw was found in the Linux kernel's bcmgenet network driver. When Energy Efficient Ethernet EEE is active on GENET hardware, a misconfiguration in the receive buffer RBUF can cause network traffic to stop flowing. This leads to a denial of service for network communications and may result in...

CVE-2026-64125

In Linux kernel BCMGENET, enabling Energy Efficient Ethernet (EEE) with RBUF_EEE_EN and RBUF_PM_EN breaks RX flow, causing frames to be dropped and rx_packets to stop incrementing; paging faults via bcmgenet_rx_poll have been observed on some hardware (e.g., Pi 4B with BCM2711/BCM54213PE). The is...

CVE-2026-64125

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: keep RBUF EEE/PM disabled Setting RBUFEEEEN | RBUFPMEN in RBUFENERGYCTRL breaks the RX path on GENET hardware once MAC EEE becomes active. RX traffic stops flowing while the link stays up and the usual descriptor/R...

Linux Distros Unpatched Vulnerability : CVE-2026-53087

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: bcmgenet: fix leaking freebds While reclaiming the tx queue we fast forward the write pointer to drop any data in flight. These dropped frames are not adde...

CVE-2026-53086

A flaw was found in the Linux kernel's bcmgenet network driver. This vulnerability arises from an overly aggressive timeout handler that attempts to reset all network transmission queues when only one experiences an issue. This behavior can create race conditions, potentially leading to system...

CVE-2026-53088

A flaw was found in the Linux kernel's bcmgenet network driver. An off-by-one error in the bcmgenetputtxcb function, related to the writeptr handling for transmit control blocks txcb, could lead to incorrect cleanup of these blocks. This issue may result in system instability or unexpected behavi...

CVE-2026-53087

A flaw was found in the Linux kernel's bcmgenet network driver. When the transmit tx queue is reclaimed, the driver incorrectly drops data frames without returning them to the pool of free buffer descriptors bds. This oversight results in a resource leak, which can lead to resource exhaustion and...

EUVD-2026-38956

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix off-by-one in bcmgenetputtxcb The writeptr points to the next open txcb. We want to return the txcb that gets rewinded, so we must rewind the pointer first then return the txcb that it points to. That way the...

EUVD-2026-38955

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix leaking freebds While reclaiming the tx queue we fast forward the write pointer to drop any data in flight. These dropped frames are not added back to the pool of free bds. We also need to tell the netdev that ...

CVE-2026-53087

Summary: CVE-2026-53087 affects the Linux kernel bcmgenet network driver. When reclaiming the transmit queue, the driver advances the write pointer to drop in-flight data but fails to return the dropped frames to the pool of free buffer descriptors (bds), causing a resource leak. This can lead to...

SUSE CVE-2023-53535

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: Add a check for oversized packets Occasionnaly we may get oversized packets from the hardware which exceed the nomimal 2KiB buffer size we allocate SKBs with. Add an early check which drops the packet to avoid...

SUSE CVE-2022-49194

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: Use stronger register read/writes to assure ordering GCC12 appears to be much smarter about its dependency tracking and is aware that the relaxed variants are just normal loads and stores and this is causing proble...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the bcmgenet driver not guaranteeing order during register reads and writes, which could lead to a transfer...

PT-2025-40677

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw related to packet handling in the bcmgenet network driver. Occasionally, oversized packets from the hardware may exceed the allocated buffer size,...
