CVE-2026-68365

The CVE concerns the Linux kernel USB serial driver for io_edgeport. The vulnerability arises because edge_interrupt_callback() adds a 16-bit transmit-credits value to txCredits without enforcing maxTxCredits. edge_write() then uses (txCredits − software FIFO count) as the data that fits, and sin...
