CVE-2026-98492

unscored Published
NVD · CVE.org

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix dma_alloc_coherent() leak on macb_alloc() error paths Fix 3 leaks in macb_alloc() error paths: - Tx buffer allocated but crossing a 4G boundary: Tx leaked. - Rx buffer allocation fails: Tx leaked. - Rx buffer allocated but crossing a 4G boundary: Tx & Rx leaked. This is because our error handling calls macb_free(bp) which in turn frees the buffers stored in bp->queues[0], but nothing has been stored in there. Fix by storing allocated buffers into bp->queues[0] ASAP.
