Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bcachefs: corrigió la validación de sb_field_downgrade - bch2_sb_downgrade_validate() no buscaba una entrada de degradación que se extendiera más allá del final de la sección de superbloque - for_each_downgrade_entry() se usa en to_text() y necesita trabajar con entradas mal formadas; También faltaba una marca para un campo que se extendía más allá del final de la sección.
