  2. Vulnerabilities (CVE)
  3. CVE-2024-26954
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16() If ->NameOffset of smb2_create_req is smaller than Buffer offset of smb2_create_req, slab-out-of-bounds read can happen from smb2_open. This patch set the minimum value of the name offset to the buffer offset to validate name length of smb2_create_req().

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ksmbd: corrige slab-out-of-bounds en smb_strndup_from_utf16() Si ->NameOffset de smb2_create_req es menor que el desplazamiento del búfer de smb2_create_req, puede ocurrir una lectura de slab-out-of-bounds de smb2_open. Este parche establece el valor mínimo del desplazamiento del nombre en el desplazamiento del búfer para validar la longitud del nombre de smb2_create_req().
