CVE-2022-50864

CVE-2022-50864 affects the Linux kernel nilfs2 where a corrupted s_log_block_size in the superblock could trigger a shift-out-of-bounds warning and kernel panic during init_nilfs() or load_nilfs(), due to a too-large exponent for a 32-bit int (exponent 38973). The issue has been resolved by addin...
