CVE-2026-43445

A flaw was found in the Linux kernel's e1000 and e1000e network drivers. When an error occurs during the mapping of transmit TX buffers, an off-by-one error in the Direct Memory Access DMA cleanup process can lead to a memory leak. This issue results in the gradual exhaustion of system resources,...
