  "description": "In the Linux kernel, the following vulnerability has been resolved:  dm-integrity: fix NULL pointer dereference when the \u0027R\u0027 flag is used  If the dm-integrity device has the SB_FLAG_DIRTY_BITMAP flag set and the user activates the device in the \u0027R\u0027 mode, a crash in dm_integrity_resume happens because the function attempts to read the journal containing the bitmap.  This patch makes dm-integrity skip any writes to the device in dm_integrity_resume if the device is activated in the \u0027R\u0027 mode.",
