CVE-2019-15921

CVE-2019-15921 : In the Linux kernel prior to 5.0.6, a memory leak occurs in genl_register_family() when idr_alloc() fails (net/netlink/genetlink.c). This can lead to resource leakage in affected systems. Root cause is a failure path not freeing partial allocations; impact is limited to memory/re...

kernel: l2tp: Race condition between pppol2tp_session_create() and l2tp_eth_create()

A race condition between pppol2tpsessioncreate and l2tpethcreate in net/l2tp/l2tpnetlink.c was found in the Linux kernel. Calling l2tptunnelfind may result in a new tunnel being created with tunnel id of a previously removed tunnel which wouldn't be protected by the reference counter...

Information Disclosure

Linux kernel is vulnerable to information disclosure attacks. This is because the netlinkdelivertapskb function in net/netlink/afnetlink.c does not restrict observations of Netlink messages to a single net namespace, when CONFIGNLMON is enabled. This allows local users to obtain sensitive...

kernel: Out-of-bounds access via an XFRM_MSG_MIGRATE xfrm Netlink message

The xfrmmigrate function in the net/xfrm/xfrmpolicy.c file in the Linux kernel built with CONFIGXFRMMIGRATE does not verify if the dir parameter is less than XFRMPOLICYMAX. This allows a local attacker to cause a denial of service out-of-bounds access or possibly have unspecified other impact by...

Kernel: ipsec: xfrm: use-after-free leading to potential privilege escalation

The Linux kernel is vulerable to a use-after-free flaw when Transformation User configuration interfaceCONFIGXFRMUSER compile-time configuration were enabled. This vulnerability occurs while closing a xfrm netlink socket in xfrmdumppolicydone. A user/process could abuse this flaw to potentially...
