Linux Kernel Net Scheduler Out-Of-Bounds Access Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of th...

CVE-2024-36968

The CVE-2024-36968 entry concerns the Linux kernel Bluetooth L2CAP path. Concrete details across connected docs show: the vulnerability arises in l2cap_le_flowctl_init() where MTU validation could fail, allowing division by zero and an integer overflow when hdev->le_mtu is out of the valid ran...

kernel: out-of-bounds write in qfq_change_class function

An out-of-bounds memory access flaw was found in the Linux kernel’s traffic control QoS subsystem in how a user triggers the qfqchangeclass function with an incorrect MTU value of the network device used as lmax. This flaw allows a local user to crash or potentially escalate their privileges on t...

CVE-2017-17432

OpenAFS 1.x before 1.6.22 does not properly validate Rx ack packets, which allows remote attackers to cause a denial of service system crash or application crash via crafted fields, as demonstrated by an integer underflow and assertion failure for a small MTU value...

kernel: MTU value is not validated in IPv6 stack causing packet loss

It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking packet loss by setting an invalid MTU value, for example, via a NetworkManager...

NetworkManager: remote DoS using IPv6 RA with bogus MTU

It was discovered that NetworkManager would set device MTUs based on MTU values received in IPv6 RAs Router Advertisements, without sanity checking the MTU value first. A remote attacker could exploit this flaw to create a denial of service attack, by sending a specially crafted IPv6 RA packet to...

CVE-2015-0272

GNOME NetworkManager allows remote attackers to cause a denial of service IPv6 traffic disruption via a crafted MTU value in an IPv6 Router Advertisement RA message, a different vulnerability than CVE-2015-8215...

CVE-2015-8215

net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel before 4.0 does not validate attempted changes to the MTU value, which allows context-dependent attackers to cause a denial of service packet loss via a value that is 1 smaller than the minimum compliant value or 2 larger than the MTU of a...
