 ("hfsplus: avoid deadlock on file truncation") unlock extree before hfsplus_free_extents(), and add check
 wheather extree is locked in hfsplus_free_extents(). However, when operations such as
 hfsplus_file_release, hfsplus_setattr, hfsplus_unlink, and hfsplus_get_block are executed concurrently in
 different files, it is very likely to trigger the WARN_ON, which will lead syzbot and xfstest to consider
 it as an abnormality. The comment above this warning also describes one of the easy triggering situations,
 which can easily trigger and cause xfstest&syzbot to report errors. [task A] [task B]
 ->hfsplus_file_release ->hfsplus_file_truncate ->hfs_find_init ->mutex_lock ->mutex_unlock
 ->hfsplus_write_begin ->hfsplus_get_block ->hfsplus_file_extend ->hfsplus_ext_read_extent ->hfs_find_init
 ->mutex_lock ->hfsplus_free_extents WARN_ON(mutex_is_locked) !!! Several threads could try to lock the
 shared extents tree. And warning can be triggered in one thread when another thread has locked the tree.
 This is the wrong behavior of the code and we need to remove the warning. (CVE-2025-38650)

Solution

Update the linux library and its related packages to version 6.1.148-1 or later.
