SUSE 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...

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...

SUSE CVE-2026-53086

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix racing timeout handler The bcmgenettimeout handler tries to take down all tx queues when a single queue times out. This is over zealous and causes many race conditions with queues that are still chugging along...

SUSE CVE-2026-53087

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-2026-53086

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...

SUSE CVE-2026-53088

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...
