CVE-2026-43283

A flaw was found in the Linux kernel's ecbhf ethernet driver. An issue in the error handling path of the dmafreecoherent function incorrectly uses priv-rxbuf.alloclen as the Direct Memory Access DMA handle instead of priv-rxbuf.allocphys. This improper unmapping of the buffer could lead to memory...
