HTTP.sys Denial of Service Vulnerability

DHCP Server Service Denial of Service Vulnerability

Microsoft Virtual Machine Bus (VMBus) Denial of Service Vulnerability

IBM MQ 9.2 LTS, 9.3 LTS, and 9.3 CD Internet Pass-Thru could allow a remote user to cause a denial of service by sending HTTP requests that would consume all available resources. IBM X-Force ID: 281278.

The icmp6_send function in net/ipv6/icmp.c in the Linux kernel through 4.8.12 omits a certain check of the dst data structure, which allows remote attackers to cause a denial of service (panic) via a fragmented IPv6 packet.

An access violation vulnerability exists in the DirectComposition functionality win32kbase.sys driver version 10.0.22000.593 as part of Windows 11 version 22000.593 and version 10.0.20348.643 as part of Windows Server 2022 version 20348.643. A specially-crafted set of syscalls can lead to a reboot. An unprivileged user can run specially-crafted code to trigger Denial Of Service.

Windows Network Address Translation (NAT) Denial of Service Vulnerability

Windows Kerberos Denial of Service Vulnerability

An out-of-bounds read vulnerability was discovered in linux kernel in the smc protocol stack, causing remote dos.

The IP stack in the Linux kernel through 4.8.2 allows remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for large crafted packets, as demonstrated by packets that contain only VLAN headers, a related issue to CVE-2016-8666.

Windows Secure Channel Denial of Service Vulnerability

.NET Core and Visual Studio Denial of Service Vulnerability

Microsoft Windows SMBv3 suffers from a null pointer dereference in versions of Windows prior to the April, 2022 patch set. By sending a malformed FileNormalizedNameInformation SMBv3 request over a named pipe, an attacker can cause a Blue Screen of Death (BSOD) crash of the Windows kernel. For most systems, this attack requires authentication, except in the special case of Windows Domain Controllers, where unauthenticated users can always open named pipes as long as they can establish an SMB session. Typically, after the BSOD, the victim SMBv3 server will reboot.

A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition.

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.

Implementations of UDP application protocol are vulnerable to network loops. An unauthenticated attacker can use maliciously-crafted packets against a vulnerable implementation that can lead to Denial of Service (DOS) and/or abuse of resources.

Internet Connection Sharing (ICS) Denial of Service Vulnerability

Windows Network Address Translation (NAT) Denial of Service Vulnerability

A vulnerability classified as problematic was found in Linux Kernel. This vulnerability affects the function macvlan_handle_frame of the file drivers/net/macvlan.c of the component skb. The manipulation leads to memory leak. The attack can be initiated remotely. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211024.

Microsoft Message Queuing (MSMQ) Denial of Service Vulnerability

In the Linux kernel, the following vulnerability has been resolved: net: sched: fix memory leak in tcindex_partial_destroy_work Syzbot reported memory leak in tcindex_set_parms(). The problem was in non-freed perfect hash in tcindex_partial_destroy_work(). In tcindex_set_parms() new tcindex_data is allocated and some fields from old one are copied to new one, but not the perfect hash. Since tcindex_partial_destroy_work() is the destroy function for old tcindex_data, we need to free perfect hash to avoid memory leak.

.NET Denial of Service Vulnerability

In the Linux kernel, the following vulnerability has been resolved: ethtool: strset: fix message length calculation Outer nest for ETHTOOL_A_STRSET_STRINGSETS is not accounted for. This may result in ETHTOOL_MSG_STRSET_GET producing a warning like: calculated message payload length (684) not sufficient WARNING: CPU: 0 PID: 30967 at net/ethtool/netlink.c:369 ethnl_default_doit+0x87a/0xa20 and a splat. As usually with such warnings three conditions must be met for the warning to trigger: - there must be no skb size rounding up (e.g. reply_size of 684); - string set must be per-device (so that the header gets populated); - the device name must be at least 12 characters long. all in all with current user space it looks like reading priv flags is the only place this could potentially happen. Or with syzbot :)

In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix potential NULL dereference The bpf_jit_binary_free() function requires a non-NULL argument. When the RISC-V BPF JIT fails to converge in NR_JIT_ITERATIONS steps, jit_data->header will be NULL, which triggers a NULL dereference. Avoid this by checking the argument, prior calling the function.

In the Linux kernel, the following vulnerability has been resolved: can: m_can: m_can_read_fifo: fix memory leak in error branch In m_can_read_fifo(), if the second call to m_can_fifo_read() fails, the function jump to the out_fail label and returns without calling m_can_receive_skb(). This means that the skb previously allocated by alloc_can_skb() is not freed. In other terms, this is a memory leak. This patch adds a goto label to destroy the skb if an error occurs. Issue was found with GCC -fanalyzer, please follow the link below for details.

The tcp_cwnd_reduction function in net/ipv4/tcp_input.c in the Linux kernel before 4.3.5 allows remote attackers to cause a denial of service (divide-by-zero error and system crash) via crafted TCP traffic.

DirectX Graphics Kernel File Denial of Service Vulnerability

A denial of service vulnerability exists when .NET Core or .NET Framework improperly handles web requests, aka '.NET Core & .NET Framework Denial of Service Vulnerability'.

There exists an auth bypass in Google Quickshare where an attacker can upload an unknown file type to a victim. The root cause of the vulnerability lies in the fact that when a Payload Transfer frame of type FILE is sent to Quick Share, the file that is contained in this frame is written to disk in the Downloads folder. Quickshare normally deletes unkown files, however an attacker can send two Payload transfer frames of type FILE and the same payload ID. The deletion logic will only delete the first file and not the second. We recommend upgrading past commit 5d8b9156e0c339d82d3dab0849187e8819ad92c0 or Quick Share Windows v1.0.2002.2

A denial of service vulnerability exists when the .NET implementation of Bond improperly parses input, aka 'Bond Denial of Service Vulnerability'.

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service.
