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-2026-43093

A flaw was found in the Linux kernel's xsk AFXDP subsystem due to insufficient validation of the User Memory UMEM headroom. This vulnerability could lead to memory corruption, specifically the skbsharedinfo data structure, if multi-buffer is enabled. Such corruption could result in system...
