  3. CVE-2023-52974
In the Linux kernel, the following vulnerability has been resolved: scsi: iscsi_tcp: Fix UAF during login when accessing the shost ipaddress If during iscsi_sw_tcp_session_create() iscsi_tcp_r2tpool_alloc() fails, userspace could be accessing the host's ipaddress attr. If we then free the session via iscsi_session_teardown() while userspace is still accessing the session we will hit a use after free bug. Set the tcp_sw_host->session after we have completed session creation and can no longer fail.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: iscsi_tcp: Se corrige el UAF durante el inicio de sesión al acceder a la dirección IP del host. Si durante iscsi_sw_tcp_session_create() falla iscsi_tcp_r2tpool_alloc(), el espacio de usuario podría estar accediendo a la dirección IP del host. Si liberamos la sesión mediante iscsi_session_teardown() mientras el espacio de usuario aún accede a ella, se producirá un error de use after free. Configure tcp_sw_host->session después de completar la creación de la sesión y ya no podrá fallar.
