[PATCH 6.1.y] scsi: sg: Fix slab-use-after-free read in sg_release()

by alvalan9＠foxmail.com

From: Suraj Sonawane <surajsonawane0215(a)gmail.com> commit f10593ad9bc36921f623361c9e3dd96bd52d85ee upstream. Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN: BUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30 kernel/locking/lockdep.c:5838 __mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912 sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407 In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) is called before releasing the open_rel_lock mutex. The kref_put() call may decrement the reference count of sfp to zero, triggering its cleanup through sg_remove_sfp(). This cleanup includes scheduling deferred work via sg_remove_sfp_usercontext(), which ultimately frees sfp. After kref_put(), sg_release() continues to unlock open_rel_lock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-use-after-free error. Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the open_rel_lock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without impacting the mutex handling in sg_release(). The fix has been tested and validated by syzbot. This patch closes the bug reported at the following syzkaller link and ensures proper sequencing of resource cleanup and mutex operations, eliminating the risk of use-after-free errors in sg_release().

From: Lizhi Xu <lizhi.xu(a)windriver.com> [ Upstream commit eb09fbeb48709fe66c0d708aed81e910a577a30a ] syzkaller reported a corrupted list in ieee802154_if_remove. [1] Remove an IEEE 802.15.4 network interface after unregister an IEEE 802.15.4 hardware device from the system.
