Executive brief
In the Linux kernel, the following vulnerability has been resolved:
f2fs: embed f2fs_gc_kthread in f2fs_sb_info
Instead of allocating f2fs_gc_kthread dynamically, embed it in f2fs_sb_info. This simplifies lifetime management and prepares for fixing race conditions during teardown.
- __sbi_store - remount|shutdown - f2fs_stop_gc_thread - access sbi->gc_thread - sbi->gc_thread = NULL - access sbi->gc_thread->f2fs_gc_task
