Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.14 has security vulnerabilities. These vulnerabilities stem from the fact that the event notify mechanism does not hold an fnl mutual exclusion lock. Additionally, the release of the notify mechanism and the netlink configuration function are not serialized. This can...

kernel: Local buffer overflow in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c

A flaw was found in the Linux kernel. A local attacker, able to inject conntrack netlink configuration, could overflow a local buffer causing crashes or triggering the use of incorrect protocol numbers in ctnetlinkparsetuplefilter in net/netfilter/nfconntracknetlink.c. The highest threat from thi...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service. Local attackers are able to inject conntrack netlink configuration to overflow a local buffer and cause a crash in ctnetlinkparsetuplefilter in net/netfilter/nfconntracknetlink.c...

Amazon Linux AMI : kernel (ALAS-2020-1446)

The version of kernel installed on the remote host is prior to 4.14.203-116.332. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1446 advisory. In binderreleasework of binder.c, there is a possible use-after-free due to improper locking. This could lead to...

Design/Logic Flaw

In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlinkparsetuplefilter in net/netfilter/nfconntracknetlink.c, aka CID-1cc5ef91d2ff...

CVE-2020-25211

CVE-2020-25211 describes a local vulnerability in the Linux kernel’s netfilter conntrack netlink path. A bounds check is missing in ctnetlink_parse_tuple_filter (net/netfilter/nf_conntrack_netlink.c), permitting a local attacker injecting conntrack netlink configuration to overflow a local buffer...
