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...

CVE-2026-43283

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ecbhf: Fix dmafreecoherent dma handle dmafreecoherent in error path takes priv-rxbuf.alloclen as the dma handle. This would lead to improper unmapping of the buffer. Change the dma handle to priv-rxbuf.allocphys...
