The vulnerability in the Routing Protocol Daemon RPD for Juniper Networks Junos OS and Junos OS Evolved involves pointer dereferencing. Exploitation of this vulnerability enables a remote attacker to cause a denial of service by sending a specially crafted BGP packet...
Expat development team Expat improper exception handling vulnerability
The Expat development team identified a vulnerability related to improper exception handling in Expat versions 2.9.0 and earlier. This vulnerability stems from improper handling of the XMLTOKNONE token generated by the externalEntityInitProcessor2 function in lib/xmlparse.c when encountering empt...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel version 4.15. It arises when KVM nVMX fails to reset the vCPU’s MMU pointer back to its root MMU upon loading L2 state in non-VM-Entry scenarios; this may result in null pointer dereferencing...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel version 5.8. It stems from a race condition between watchqueuesetsize and postonenotification, which can lead to dereferencing when notes remain NULL. This may result in null pointer dereferencing and kernel crashes...
Improper handling of exceptions in Tanium Enforce
Versions prior to Tanium Enforce 2.9.736, versions prior to 2.10.778, and versions prior to 3.0.373 contain an improper exception handling vulnerability. This vulnerability stems from null pointer dereferencing and may lead to denial-of-service attacks...
Juniper Networks RPD DoS
The vulnerability in the Routing Protocol Daemon RPD for Juniper Networks Junos OS and Junos OS Evolved involves pointer dereferencing. Exploitation of this vulnerability may allow a remote attacker to cause a denial of service...
Linux kernel security vulnerabilities
Security vulnerabilities exist in Linux kernel versions from 6.18.53 up to 6.18.57 and from 7.2.7 up to 7.2.11. These vulnerabilities arise when kernel page tables are delayed during bootup; the work queue is not yet initialized, potentially leading to null pointer dereferencing and kernel crashe...
Apple iOS security vulnerabilities
A security vulnerability exists in Apple iOS versions prior to 27, Apple iPadOS versions prior to 27, Apple macOS Golden Gate versions prior to 27, Apple macOS Tahoe versions prior to 26.7.2, Apple tvOS versions prior to 27, Apple visionOS versions prior to 27, and Apple watchOS versions prior to...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel version 4.5. It arises because the V3D unbind process fails to clear suspend check timers and work queues; this may allow reading V3D registers via an empty vc4-v3d pointer, leading to null pointer dereferencing and use-after-free conditions...
Linux kernel security vulnerabilities
Security vulnerabilities exist in Linux kernel versions from 4.4.281 up to 4.5, from 4.9.280 up to 4.10, from 4.14.244 up to 4.15, from 4.19.203 up to 4.20, from 5.4.140 up to 5.5, from 5.10.58 up to 5.11, from 5.13.10 up to 5.14, and specifically in version 5.14. The vulnerability arises because...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel version 5.8. It stems from improper rejection of automatic mounts under mount points that are not owned by the caller. countmounts dereferences an invalid pointer within MNTNSINTERNAL, potentially leading to null pointer dereferencing and a kernel...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel versions prior to 5.10.271, 5.15.222, 6.1.189, 6.6.158, 6.12.111, and 6.18.53. This vulnerability arises from the failure to disable VLPI when ITS is not detected. When the setting vmnicgicv4enable=1 is incorrectly configured on systems lacking MSI...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel versions prior to 7.2.9. It stems from the lack of checks on empty stream-sink values within the DPMS sequence before dereferencing, potentially leading to null pointer dereferencing...
Linux kernel security vulnerabilities
A security vulnerability exists in Linux kernel version 5.12. It arises because, after checking the number of paths in fibnlmsgsize, fibinfonhc fails to handle the case where RTMNEWNEXTHOP reduces the path count; this results in a NULL return value, potentially leading to null pointer dereferenci...
FreeRDP RDP DoS
