Summary
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() isn't 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. task:fsstress state:D stack:0 pid:374 tgid:374 ppid:373 task_flags:0x440140 flags:0x00000000 Call Trace: <TASK> __schedule+0x2c9/0x7f0 schedule+0x27/0xa0 schedule_preempt_disabled+0x15/0x30 rwsem_down_read_slowpath+0x278/0x4c0 down_read+0x59/0xb0 page_cache_ra_unbounded+0x65/0x1b0 filemap_get_pages+0x124/0x3e0 filemap_read+0x114/0x3d0 vfs_read+0x297/0x360 ksys_read+0x6c/0xe0 do_syscall_64+0x4b/0x110 entry_SYSCALL_64_after_hwframe+0x76/0x7e
