In the Linux kernel, the following vulnerability has been resolved:
ext4: goto right label out_mmap_sem in ext4_setattr()
Otherwise, if ext4_inode_attach_jinode() fails, a hung task will
happen because filemap_invalidate_unlock() isnt called to unlock
mapping->invalidate_lock. Like this:
EXT4-fs error (device sda) in ext4_setattr:5557: Out of memory
INFO: task fsstress:374 blocked for more than 122 seconds.
Not tainted 6.14.0-rc1-next-20250206-xfstests-dirty #726
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
