CVE-2026-53087 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix leaking free_bds 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 we are dropping said data.
A vulnerability in the Linux kernel's handling of the Broadcom BCMGENET Ethernet driver has been addressed. The issue involved a memory management flaw where dropped transmission frames were not returned to the pool of available buffer descriptors, leading to a gradual depletion of free resources. This problem has been fixed by modifying the buffer management logic to properly account for these dropped frames.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
