Описание

In the Linux kernel, the following vulnerability has been resolved: ext4: reject mount if bigalloc with s_first_data_block != 0 bigalloc with s_first_data_block != 0 is not supported, reject mounting it.

A flaw was found in the ext4 filesystem component of the Linux kernel. This vulnerability occurs when a local user attempts to mount an ext4 filesystem that is configured with bigalloc and a non-zero s_first_data_block value, a configuration that is not supported. The consequence is a Denial of Service (DoS), as the system will reject the mount operation, preventing access to the filesystem.
