If\nthis inconsistent behavior is not due to a previously fixed bug, then an\nunexpected race is occurring, so return a temporary error -EAGAIN instead.\n\nThis prevents callers such as __block_write_begin_int() from requesting a\nread into a buffer that is not mapped, which would cause the BUG_ON check\nfor the BH_Mapped flag in submit_bh_wbc() to fail."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: nilfs2: previene el error del kernel en submit_bh_wbc(). Se corrige un error por el cual nilfs_get_block() devuelve un estado exitoso cuando la b\u00fasqueda y la inserci\u00f3n del bloque especificado fallan de manera inconsistente. Si este comportamiento inconsistente no se debe a un error solucionado previamente, entonces se est\u00e1 produciendo una ejecuci\u00f3n inesperada, por lo que se devuelve un error temporal -EAGAIN. Esto evita que llamadores como __block_write_begin_int() soliciten una lectura en un b\u00fafer que no est\u00e1 asignado, lo que provocar\u00eda que falle la verificaci\u00f3n BUG_ON del indicador BH_Mapped en submit_bh_wbc()."
