CVE-2026-53087
Description
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 potentially cause a denial of service (DoS) for network functionality.
