fib-advies.nl Improper Access Control vulnerability OBB-3866256

Following the coordinated and responsible vulnerability disclosure guidelines of the ISO 29147 standard, Open Bug Bounty has: a. verified the vulnerability and confirmed its existence; b. notified the website operator about its existence. Technical details of the vulnerability are currently hidde...

The vulnerability of the fib_rules_lookup() function in the Linux operating system’s IPv6 kernel module allows a hacker to cause a service failure.

The vulnerability of the fibruleslookup function in the Linux IPv6 kernel module is related to access to resources through incompatible types when processing the values of rt6info and fib6info in the arg.result parameter. Exploiting this vulnerability could allow an attacker to cause a service...

UBUNTU-CVE-2023-3022

A flaw was found in the IPv6 module of the Linux kernel. The arg.result was not used consistently in fib6rulelookup, sometimes holding rt6info and other times fib6info. This was not accounted for in other parts of the code where rt6info was expected unconditionally, potentially leading to a kerne...

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...

kernel: ipv4: Fix a data-race around sysctl_fib_sync_mem.

In the Linux kernel, the following vulnerability has been resolved: ipv4: Fix a data-race around sysctlfibsyncmem. While reading sysctlfibsyncmem, it can be changed concurrently. So, we need to add READONCE to avoid a data-race...

kernel: out-of-bounds read in fib_nh_match of the file net/ipv4/fib_semantics.c

An out-of-bounds memory read flaw was found in the Linux kernel. The IPv4 Handler component may delete IPv4 routes containing a multipath spec while the fibinfo is using a nexthop object. This issue allows a local attacker access to unauthorized data...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A data-race issue exists around sysctl fib sync mem in the Linux kernel. The problem occurs because sysctl fib sync mem can be changed concurrently while being read, which can lead to...

SUSE CVE-2005-1041

The fibseqstart function in fibhash.c in Linux kernel allows local users to cause a denial of service system crash via /proc/net/route...

SUSE CVE-2005-4635

The nlfibinput function in fibfrontend.c in the Linux kernel before 2.6.15 does not check for valid lengths of the header and payload, which allows remote attackers to cause a denial of service invalid memory reference via malformed fiblookup netlink messages...

SUSE CVE-2007-1861

The nlfiblookup function in net/ipv4/fibfrontend.c in Linux Kernel before 2.6.20.8 allows attackers to cause a denial of service kernel panic via NETLINKFIBLOOKUP replies, which trigger infinite recursion and a stack overflow...

SUSE CVE-2016-6480

Race condition in the ioctlsendfib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows local users to cause a denial of service out-of-bounds access or system crash by changing a certain size value, aka a "double fetch" vulnerability...

SUSE CVE-2017-13686

net/ipv4/route.c in the Linux kernel 4.13-rc1 through 4.13-rc6 is too late to check for a NULL fi field when RTMFFIBMATCH is set, which allows local users to cause a denial of service NULL pointer dereference or possibly have unspecified other impact via crafted system calls. NOTE: this does not...

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...

SUSE CVE-2022-3435

A vulnerability classified as problematic has been found in Linux Kernel. This affects the function fibnhmatch of the file net/ipv4/fibsemantics.c of the component IPv4 Handler. The manipulation leads to out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to appl...
