Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ext4: use memtostr_pad() for s_volume_name

As with the other strings in struct ext4_super_block, s_volume_name is
not NUL terminated. The other strings were marked in commit 072ebb3bffe6
("ext4: add nonstring annotations to ext4.h"). Using strscpy() isn't
the right replacement for strncpy(); it should use memtostr_pad()
instead.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ext4: use memtostr_pad() para s_volume_name Al igual que con las otras cadenas en la estructura ext4_super_block, s_volume_name no tiene terminación NUL. Las otras cadenas se marcaron en el commit 072ebb3bffe6 ("ext4: agregue anotaciones que no sean cadenas a ext4.h"). Usar strscpy() no es el reemplazo adecuado para strncpy(); debería usar memtostr_pad() en su lugar.
