CVE-2021-47527

Summary: CVE-2021-47527 affects the Linux kernel’s serial core. The root cause was a transmit-buffer not freed on final close after switching to tty_port_close, which could cause the buffer to remain uncleared (stalling ioctl drains) and could leak on driver unbind. The issue has been fixed in th...
