CVE-2022-50286

The CVE-2022-50286 issue affects the Linux kernel ext4 file system in scenarios where bigalloc and inline options are used simultaneously. The root cause is in ext4_clu_mapped: when converting inline-stored data to extents, the code may search the (non-existent) extent tree to decide if a block s...
