Vulnerability from github – Published: 2022-05-24 19:15 – Updated: 2022-07-09 00:00A vulnerability in the authentication, authorization, and accounting (AAA) function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass NETCONF or RESTCONF authentication and do either of the following: Install, manipulate, or delete the configuration of an affected device Cause memory corruption that results in a denial of service (DoS) on an affected device This vulnerability is due to an uninitialized variable. An attacker could exploit this vulnerability by sending a series of NETCONF or RESTCONF requests to an affected device. A successful exploit could allow the attacker to use NETCONF or RESTCONF to install, manipulate, or delete the configuration of a network device or to corrupt memory on the device, resulting a DoS.

Vulnerability from github – Published: 2022-05-24 19:05 – Updated: 2023-03-15 00:30An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the 'tftp_t' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.

Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-07-14 21:31In the Linux kernel, the following vulnerability has been resolved:
fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal
CXL is linked before fwctl in drivers/Makefile. Both use module_init, socxl_pci_driver_init()runs first. Whencxl_pci_probe()callsfwctl_register()and thendevice_add(), fwctl_class is not yet
registered because fwctl_init() hasn't run, causingclass_to_subsys()` to
return NULL and skip knode_class initialization.
On device removal, class_to_subsys() returns non-NULL, and
device_del() calls klist_del() on the uninitialized knode, triggering
a NULL pointer dereference.

GHSA-QPXP-M556-4MCR
Vulnerability from github – Published: 2025-10-09 18:30 – Updated: 2025-10-09 18:30An Access of Uninitialized Pointer vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved with BGP sharding configured allows an attacker triggering indirect next-hop updates, along with timing outside the attacker's control, to cause rpd to crash and restart, leading to a Denial of Service (DoS).
With BGP sharding enabled, triggering route resolution of an indirect next-hop (e.g., an IGP route change over which a BGP route gets resolved), may cause rpd to crash and restart. An attacker causing continuous IGP route churn, resulting in repeated route re-resolution, will increase the likelihood of triggering this issue, leading to a potentially extended DoS condition.
This issue affects:
Junos OS:
- all versions before 21.4R3-S6,
- from 22.1 before 22.1R3-S6,
- from 22.2 before 22.2R3-S3,
- from 22.3 before 22.3R3-S3,
- from 22.4 before 22.4R3,
- from 23.2 before 23.2R2;
Junos OS Evolved:
- all versions before 22.3R3-S3-EVO,
- from 22.4 before 22.4R3-EVO,
- from 23.2 before 23.2R2-EVO.
Versions before Junos OS 21.3R1 and Junos OS Evolved 21.3R1-EVO are unaffected by this issue.
