This is a note to let you know that I've just added the patch titled scsi: hpsa: Fix allocation size for scsi_host_alloc() to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: scsi-hpsa-fix-allocation-size-for-scsi_host_alloc.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1cac65f0e2c02bb32ba4a2ae39f875dff506c139 Author: Alexey V. Vissarionov <gremlin@xxxxxxxxxxxx> Date: Wed Jan 18 06:12:55 2023 +0300 scsi: hpsa: Fix allocation size for scsi_host_alloc() [ Upstream commit bbbd25499100c810ceaf5193c3cfcab9f7402a33 ] The 'h' is a pointer to struct ctlr_info, so it's just 4 or 8 bytes, while the structure itself is much bigger. Found by Linux Verification Center (linuxtesting.org) with SVACE. Fixes: edd163687ea5 ("hpsa: add driver for HP Smart Array controllers.")
