- kernel: heap overflow in marvell/mwifiex/tdls.c (CVE-2019-14901)

- kernel: powerpc: local user can read vector registers of other users' processes via an interrupt (CVE-2019-15031)

- kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash (CVE-2019-15099)

- kernel: out-of-bounds array access in __xfrm_policy_unlink (CVE-2019-15666)
