CVE-2016-4997 WRITEUP HIGH WRITEUP
Linux Kernel 4.6.3 Netfilter Privilege Escalation
The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter subsystem in the Linux kernel before 4.6.3 allow local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement.
CVSS 7.8
CVE-2016-4998 WRITEUP HIGH WRITEUP
Linux Kernel < 4.6 - Denial of Service via IPT_SO_SET_REPLACE Out-of-Bounds Read
The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel before 4.6 allows local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary.
CVSS 7.1
CVE-2023-32233 WRITEUP HIGH WRITEUP
Linux Kernel 3.13-6.3.1 - Use-After-Free in Netfilter nf_tables via Anonymous Set Mishandling
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.
CVSS 7.8
CVE-2012-6689 WRITEUP HIGH WRITEUP
Linux Kernel < 3.5.5 - Unauthenticated Netlink Message Spoofing via dst_pid Field
The netlink_sendmsg function in net/netlink/af_netlink.c in the Linux kernel before 3.5.5 does not validate the dst_pid field, which allows local users to have an unspecified impact by spoofing Netlink messages.
CVSS 7.8
CVE-2015-1573 WRITEUP MEDIUM WRITEUP
Linux Kernel < 3.18.5 - Denial of Service via nft_flush_table Cross-Chain Jump Mishandling
The nft_flush_table function in net/netfilter/nf_tables_api.c in the Linux kernel before 3.18.5 mishandles the interaction between cross-chain jumps and ruleset flushes, which allows local users to cause a denial of service (panic) by leveraging the CAP_NET_ADMIN capability.
CVSS 5.5
CVE-2018-1065 WRITEUP MEDIUM WRITEUP
Linux Kernel < 4.15.7 - Denial of Service via Netfilter Rule Blob NULL Pointer Dereference
The netfilter subsystem in the Linux kernel through 4.15.7 mishandles the case of a rule blob that contains a jump but lacks a user-defined chain, which allows local users to cause a denial of service (NULL pointer dereference) by leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in net/ipv6/netfilter/ip6_tables.c.
CVSS 4.7
CVE-2022-39190 WRITEUP MEDIUM WRITEUP
Linux Kernel < 5.19.6 - Denial of Service via Chain Binding
An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain.
CVSS 5.5
CVE-2023-6622 WRITEUP MEDIUM WRITEUP
Linux kernel - DoS
A null pointer dereference vulnerability was found in nft_dynset_init() in net/netfilter/nft_dynset.c in nf_tables in the Linux kernel. This issue may allow a local attacker with CAP_NET_ADMIN user privilege to trigger a denial of service.
