CVE-2022-50277

CVE-2022-50277 concerns the Linux kernel ext4 subsystem. When mounting a filesystem with the journal inode having the encrypt flag, a NULL dereference can occur in fscrypt_limit_io_blocks() via the path jbd2_journal_init_inode() → ext4_iomap_begin() → fscrypt_limit_io_blocks(). The issue arises b...
