2018-05-01ALSA: asihpi: Hardening for potential Spectre v1Takashi Iwai1-4/+9
commit f9d94b57e30fd1575b4935045b32d738668aa74b upstream. As recently Smatch suggested, a couple of places in ASIHPI driver may expand the array directly from the user-space value with speculation: sound/pci/asihpi/hpimsginit.c:70 hpi_init_response() warn: potential spectre issue 'res_size' (local cap) sound/pci/asihpi/hpioctl.c:189 asihpi_hpi_ioctl() warn: potential spectre issue 'adapters' This patch puts array_index_nospec() for hardening against them.
