From: Prasad J Pandit <p...@fedoraproject.org> Hello,
* First patch fixes an OOB access issue which may occur when a guest user sets 'reply_queue_head' field to a negative or large positive value, via 'struct mfi_init_qinfo' object in megasas_init_firmware(), such that 'index' variables in megasas_lookup_frame() goes beyond the s->frames[MEGASAS_MAX_FRAMES=2048] array bounds. -> https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg03131.html * Second patch fixes a NULL pointer dereference issue which may occur if megasas_enqueue_frame() routine returns a NULL frame for a given 'frame_addr' address. -> https://bugs.launchpad.net/qemu/+bug/1878259 * Third patch updates other numeric fields of MegasasState to unsigned type. Thank you. -- Prasad J Pandit (3): megasas: use unsigned type for reply_queue_head and check index megasas: avoid NULL pointer dereference megasas: use unsigned type for positive numeric fields hw/scsi/megasas.c | 44 ++++++++++++++++++++++---------------------- 1 file changed, 22 insertions(+), 22 deletions(-) -- 2.25.4
