  3. CVE-2024-57943
In the Linux kernel, the following vulnerability has been resolved: exfat: fix the new buffer was not zeroed before writing Before writing, if a buffer_head marked as new, its data must be zeroed, otherwise uninitialized data in the page cache will be written. So this commit uses folio_zero_new_buffers() to zero the new buffers before ->write_end().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: exfat: se corrige que el nuevo búfer no se pusiera a cero antes de escribir. Antes de escribir, si un buffer_head está marcado como nuevo, sus datos deben ponerse a cero; de lo contrario, se escribirán datos no inicializados en la caché de páginas. Por lo tanto, esta confirmación utiliza folio_zero_new_buffers() para poner a cero los nuevos búferes antes de ->write_end().
