CVE-2024-57925

  2. Vulnerabilities (CVE)
  3. CVE-2024-57925
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix a missing return value check bug In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct() fails to allocate a node, it returns a NULL pointer to the in_work pointer. This can lead to an illegal memory write of in_work->response_buf when allocate_interim_rsp_buf() attempts to perform a kzalloc() on it. To address this issue, incorporating a check for the return value of ksmbd_alloc_work_struct() ensures that the function returns immediately upon allocation failure, thereby preventing the aforementioned illegal memory access.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ksmbd: se corrige un error de comprobación del valor de retorno faltante En smb2_send_interim_resp(), si ksmbd_alloc_work_struct() no puede asignar un nodo, devuelve un puntero NULL al puntero in_work. Esto puede provocar una escritura de memoria ilegal de in_work->response_buf cuando allocate_interim_rsp_buf() intenta realizar un kzalloc() en él. Para solucionar este problema, la incorporación de una comprobación del valor de retorno de ksmbd_alloc_work_struct() garantiza que la función regrese inmediatamente después de un error de asignación, lo que evita el acceso ilegal a la memoria mencionado anteriormente.
