Title
Junos OS: ACX5448 & ACX710: Due to interface flaps the PFE process can crash
Summary
A Missing Synchronization vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on ACX5448 and ACX710 allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).
If an interface flaps while the system gathers statistics on that interface, two processes simultaneously access a shared resource which leads to a PFE crash and restart.
This issue affects Junos OS:
* All versions before 20.4R3-S9,
* 21.2 versions before 21.2R3-S5,
* 21.3 versions before 21.3R3-S5,
* 21.4 versions before 21.4R3-S4,
* 22.1 versions before 22.1R3-S2,
* 22.2 versions before 22.2R3-S2,
* 22.3 versions before 22.3R2-S2, 22.3R3,
* 22.4 versions before 22.4R2.

Title
Media caddy removal and reinsertion without reboot may cause data loss
Summary
An issue exists in SoftIron HyperCloud where drive caddy removal and reinsertion without a reboot may erroneously cause the system to recognize the caddy as new media and wipe all data on the drives due to a missing synchronization flaw, which impacts data availability and integrity.
This issue only impacts SoftIron HyperCloud "density" storage nodes running HyperCloud software versions 1.0 to before 2.0.3.

Summary
Grafana is an open-source platform for monitoring and observability.
Using public dashboards users can query multiple distinct data sources using mixed queries. However such query has a possibility of crashing a Grafana instance.
The only feature that uses mixed queries at the moment is public dashboards, but it's also possible to cause this by calling the query API directly.
This might enable malicious users to crash Grafana instances through that endpoint.
Users may upgrade to version 9.4.12 and 9.5.3 to receive a fix.

CVE-2022-50238 (GCVE-0-2022-50238)
Vulnerability from cvelistv5 – Published: 2025-09-08 00:00 – Updated: 2025-11-17 16:01 Disputed

Summary
The on-endpoint Microsoft vulnerable driver blocklist is not fully synchronized with the online Microsoft recommended driver block rules. Some entries present on the online list have been excluded from the on-endpoint blocklist longer than the expected periodic monthly Windows updates. It is possible to fully synchronize the driver blocklist using WDAC policies. NOTE: The vendor explains that Windows Update provides a smaller, compatibility-focused driver blocklist for general users, while the full XML list is available for advanced users and organizations to customize at the risk of usability issues.
