In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix SError in ufshcd_rtc_work() during UFS suspend
In __ufshcd_wl_suspend(), cancel_delayed_work_sync() is called to cancel
the UFS RTC work, but it is placed after ufshcd_vops_suspend(hba, pm_op,
POST_CHANGE). This creates a race condition where ufshcd_rtc_work() can
still be running while ufshcd_vops_suspend() is executing. When
UFSHCD_CAP_CLK_GATING is not supported, the condition
!hba->clk_gating.active_reqs is always true, causing ufshcd_update_rtc()
to be executed. Since ufshcd_vops_suspend() typically performs clock
gating operations, executing ufshcd_update_rtc() at that moment triggers
an SError. The kernel panic trace is as follows:
Kernel panic - not syncing: Asynchronous SError Interrupt

Fix this by moving cancel_delayed_work_sync() before the call to
ufshcd_vops_suspend(hba, pm_op, PRE_CHANGE), ensuring the UFS RTC work is
fully completed or cancelled at that point.
