n the Linux kernel, the following vulnerability has been resolved: ksmbd: check outstanding simultaneous SMB operations If Client send simultaneous SMB operations to ksmbd, It exhausts too much memory through the "ksmbd_work_cache”. It will cause OOM issue. ksmbd has a credit mechanism but it can't handle this problem. This patch add the check if it exceeds max credits to prevent this problem by assuming that one smb request consumes at least one credit.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ksmbd: comprobar operaciones SMB simultáneas pendientes Si el cliente envía operaciones SMB simultáneas a ksmbd, agota demasiada memoria a través de "ksmbd_work_cache". Esto provocará un problema de OOM. ksmbd tiene un mecanismo de crédito, pero no puede solucionar este problema. Este parche agrega la comprobación si excede los créditos máximos para evitar este problema al suponer que una solicitud SMB consume al menos un crédito.
