CVE-2023-54311

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

ext4: fix deadlock when converting an inline directory in nojournal mode

In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock by calling ext4_handle_dirty_dirblock() when it already has taken the directory lock. There is a similar self-deadlock in ext4_incvert_inline_data_nolock() for data files which we'll fix at the same time.

A simple reproducer demonstrating the problem:
