AI-suggested
A patch is available and included in Linux kernel updates version 6.14.0-1007.7, 6.14.0-1012.12, and several specific 3.11 to 3.13 kernel builds. Users should update to these fixed kernel versions or later to remediate the issue. No additional mitigation is required beyond applying the official kernel updates provided by vendors such as Ubuntu.
Description
A vulnerability in the Linux kernel's dmaengine subsystem related to the ti: k3-udma-glue driver was resolved. The issue involved improper handling of the skip_fdq argument in the k3_udma_glue_reset_rx_chn() function, which could cause incorrect clearing of flow descriptor queues depending on the DMA architecture. This flaw was fixed by inferring the DMA architecture internally rather than relying on user input. The vulnerability affected certain Texas Instruments network drivers and could cause kernel warnings and instability. A patch is available as part of a broader Linux kernel security update.
