CVE-2024-56750

In the Linux kernel, the following vulnerability has been resolved: erofs: fix blksize < PAGE_SIZE for file-backed mounts Adjust sb->s_blocksize{,_bits} directly for file-backed mounts when the fs block size is smaller than PAGE_SIZE. Previously, EROFS used sb_set_blocksize(), which caused a panic if bdev-backed mounts is not used.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: erofs: corrige blksize < PAGE_SIZE para montajes respaldados por archivos Ajuste sb->s_blocksize{,_bits} directamente para montajes respaldados por archivos cuando el tamaño de bloque fs es menor que PAGE_SIZE. Anteriormente, EROFS usaba sb_set_blocksize(), que causaba un pánico si no se usaban montajes respaldados por bdev.
