CVE-2025-37978
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: block: integrity: Do not call set_page_dirty_lock() Placing multiple protection information buffers inside the same page can lead to oopses because set_page_dirty_lock() can't be called from interrupt context. Since a protection information buffer is not backed by a file there is no point in setting its page dirty, there is nothing to synchronize. Drop the call to set_page_dirty_lock() and remove the last argument to bio_integrity_unpin_bvec().

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bloque: integridad: No llamar a set_page_dirty_lock(). Colocar varios búferes de información de protección dentro de la misma página puede provocar errores, ya que set_page_dirty_lock() no se puede llamar desde el contexto de interrupción. Dado que un búfer de información de protección no está respaldado por un archivo, no tiene sentido configurar su página como sucia; no hay nada que sincronizar. Elimine la llamada a set_page_dirty_lock() y elimine el último argumento de bio_integrity_unpin_bvec()."
