The vulnerability of the fib4_rule_action() function in the net/ipv4/fibRules.c module of the IPv4 protocol implementation in the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the fib4ruleaction function in the net/ipv4/fibrules.c module of the Linux operating system’s IPv4 kernel implementation is related to improper memory release before deleting the last pointer memory leak. Exploiting this vulnerability could allow an attacker to cause a servic...

The vulnerability of the __fib6_rule_action() function in the Linux operating system’s IPv6 kernel implementation allows a hacker to induce a service failure.

The vulnerability of the fib6ruleaction function in the net/ipv6/fib6rules.c module of the Linux operating system’s IPv6 kernel implementation is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure remotely...

SUSE CVE-2021-47546

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix memory leak in fib6rulesuppress The kernel leaks memory when a fib rule is present in IPv6 nftables firewall rules and a suppressprefix rule is present in the IPv6 routing rules used by certain tools such as wg-quick. I...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux Kernel has a code issue vulnerability that stems from a flaw in the IPv6 module where arg.result is used inconsistently in fib6rulelookup, sometimes holding rt6info and...

SUSE CVE-2019-20422

In the Linux kernel before 5.3.4, fib6rulelookup in net/ipv6/ip6fib.c mishandles the RT6LOOKUPFDSTNOREF flag in a reference-count decision, leading to for example a crash that was identified by syzkaller, aka CID-7b09c2d052db...

CVE-2019-18198

In the Linux kernel before 5.3.4, a reference count usage error in the fib6rulesuppress function in the fib6 suppression feature of net/ipv6/fib6rules.c, when handling the FIBLOOKUPNOREF flag, can be exploited by a local attacker to corrupt memory, aka CID-ca7a03c41753...
