A remote stack overflow in the TIPC networking module. With FORTIFYSOURCE's stricter memcpy() bounds checking, this can be exploited to cause remote DOS via kernel panic on systems using TIPC. Prior to these bounds checks, and with a canary leak (or no CONFIGSTACKPROTECTOR), this can be exploited for RCE.

A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiexuapparsetailies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.

In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfsrq's, which allows attackers to cause a denial of service (infinite loop in updateblockedaverages) or possibly have unspecified other impact by inducing a high load.
