superio_ioport_readb can read the 256th element of the array. Coverity reports an out-of-bounds write in superio_ioport_writeb, but it does not show the corresponding out-of-bounds read because it cannot prove that it can happen. Fix the root cause of the problem (zhanghailang's patch instead fixes the logic in superio_ioport_writeb).Signed-off-by: Paolo Bonzini <pbonz...@redhat.com> --- hw/isa/vt82c686.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hw/isa/vt82c686.c b/hw/isa/vt82c686.c index e0c235c..a43e26d 100644 --- a/hw/isa/vt82c686.c +++ b/hw/isa/vt82c686.c @@ -36,7 +36,7 @@ typedef struct SuperIOConfig { - uint8_t config[0xff]; + uint8_t config[0x100]; uint8_t index; uint8_t data; } SuperIOConfig;
