kernel: ip_vti: fix potential slab-use-after-free in decode_session6

A use-after-free flaw was found in the Linux kernel's ipvti IPsec Virtual Tunnel Interface implementation when transmitting IPv6 packets with the SFB qdisc attached. A local user with CAPNETADMIN capability can trigger this issue by configuring an ipvti interface with an SFB qdisc and sending IPv...

kernel: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests

A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel memory. This flaw allows a local user with CAPNETADMIN capability to crash or potentially...

Kernel: tracing: NULL pointer dereference

The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service NULL pointer dereference and system crash or possibly have unspecified other impact by leveraging the CAPSYSADMIN capability for write access to the 1 setftracepid or 2 setgraphfunction file...

kernel: ipv4: netfilter: ip_tables: fix infoleak to userspace

net/ipv4/netfilter/iptables.c in the IPv4 implementation in the Linux kernel before 2.6.39 does not place the expected '\0' character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive information from kernel memory by...
