CVE-2024-26980

  2. Vulnerabilities (CVE)
  3. CVE-2024-26980
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_buf If ->ProtocolId is SMB2_TRANSFORM_PROTO_NUM, smb2 request size validation could be skipped. if request size is smaller than sizeof(struct smb2_query_info_req), slab-out-of-bounds read can happen in smb2_allocate_rsp_buf(). This patch allocate response buffer after decrypting transform request. smb3_decrypt_req() will validate transform request size and avoid slab-out-of-bound in smb2_allocate_rsp_buf().

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ksmbd: corrige slab-out-of-bounds en smb2_allocate_rsp_buf Si ->ProtocolId es SMB2_TRANSFORM_PROTO_NUM, se podría omitir la validación del tamaño de la solicitud smb2. Si el tamaño de la solicitud es menor que sizeof (struct smb2_query_info_req), la lectura de losa fuera de los límites puede ocurrir en smb2_allocate_rsp_buf(). Este parche asigna un búfer de respuesta después de descifrar la solicitud de transformación. smb3_decrypt_req() validará el tamaño de la solicitud de transformación y evitará la losa fuera de los límites en smb2_allocate_rsp_buf().
