CVE-2022-49767

CVE-2022-49767 affects the Linux kernel 9p/trans_fd path. The issue arises because p9_mux_poll_stop() could fail to interrupt blocking kernel_read()/kernel_write() on pipes due to fd_open() not setting O_NONBLOCK, whereas socket paths already use O_NONBLOCK. A minimal patch makes O_NONBLOCK alway...
