kernel: rxrpc: fix oversized RESPONSE authenticator length check

A flaw was found in the Linux kernel's rxrpc component. An inverted length check in the rxgkverifyresponse function allows oversized RESPONSE authenticators to be accepted. This can lead to an impossible length being passed to skbtosgvec, triggering a BUGON condition and resulting in a system...

kernel: net: Heap overflow in skb_to_sgvec in macsec.c

A flaw was found in the way Linux kernel allocates heap memory to build the scattergather list from a fragment listskbshinfoskb-fraglist in the socket bufferskbbuff. The heap overflow occurred if 'MAXSKBFRAGS + 1' parameter and 'NETIFFFRAGLIST' feature are both used together. A remote user or...

CVE-2017-7477

Heap-based buffer overflow in drivers/net/macsec.c in the MACsec module in the Linux kernel through 4.10.12 allows attackers to cause a denial of service or possibly have unspecified other impact by leveraging the use of a MAXSKBFRAGS+1 size in conjunction with the NETIFFFRAGLIST feature, leading...
