In the Linux kernel, the following vulnerability has been resolved: io_uring/net: fix io_req_post_cqe abuse by send bundle [ 114.987980][ T5313] WARNING: CPU: 6 PID: 5313 at io_uring/io_uring.c:872 io_req_post_cqe+0x12e/0x4f0 [ 114.991597][ T5313] RIP: 0010:io_req_post_cqe+0x12e/0x4f0 [ 115.001880][ T5313] Call Trace: [ 115.002222][ T5313] <TASK> [ 115.007813][ T5313] io_send+0x4fe/0x10f0 [ 115.009317][ T5313] io_issue_sqe+0x1a6/0x1740 [ 115.012094][ T5313] io_wq_submit_work+0x38b/0xed0 [ 115.013223][ T5313] io_worker_handle_work+0x62a/0x1600 [ 115.013876][ T5313] io_wq_worker+0x34f/0xdf0 As the comment states, io_req_post_cqe() should only be used by multishot requests, i.e. REQ_F_APOLL_MULTISHOT, which bundled sends are not. Add a flag signifying whether a request wants to post multiple CQEs. Eventually REQ_F_APOLL_MULTISHOT should imply the new flag, but that's left out for simplicity.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: io_uring/net: corrección del abuso de io_req_post_cqe por parte del paquete de envío [ 114.987980][ T5313] ADVERTENCIA: CPU: 6 PID: 5313 en io_uring/io_uring.c:872 io_req_post_cqe+0x12e/0x4f0 [ 114.991597][ T5313] RIP: 0010:io_req_post_cqe+0x12e/0x4f0 [ 115.001880][ T5313] Rastreo de llamadas: [ 115.002222][ T5313] [ 115.007813][ T5313] io_send+0x4fe/0x10f0 [ 115.009317][ T5313] io_issue_sqe+0x1a6/0x1740 [ 115.012094][ T5313] io_wq_submit_work+0x38b/0xed0 [ 115.013223][ T5313] io_worker_handle_work+0x62a/0x1600 [ 115.013876][ T5313] io_wq_worker+0x34f/0xdf0 Como se indica en el comentario, io_req_post_cqe() solo debe usarse en solicitudes multienvío, como REQ_F_APOLL_MULTISHOT, que no se usan en envíos agrupados. Agregue un indicador que indique si una solicitud desea publicar múltiples CQE. Finalmente, REQ_F_APOLL_MULTISHOT debería implicar la nueva bandera, pero esto se omite para simplificar.
