CVE-2026-33800 HIGH PATCH This Week

Denial-of-service in the Packet Forwarding Engine of Juniper Junos OS on MX Series routers allows an unauthenticated, network-adjacent attacker to crash and restart the FPC by continuously flapping Micro-BFD sessions. The PFEMAN process queues each up/down event and, in a Virtual-Chassis deployment with locality-bias enabled, processing is slow enough that a sustained flap backlog prevents completion and trips the PFEMAN watchdog timer, forcing an FPC restart and a full traffic outage. No public exploit identified at time of analysis and the issue is not in CISA KEV, but the low complexity and unauthenticated adjacent vector make it a credible availability threat to affected line cards (MPC9 and below).

CVE-2026-15172 MEDIUM PATCH This Month

The FMP/NOTIFY protocol dissector in Wireshark 4.6.0-4.6.6 and 4.4.0-4.4.16 crashes when processing malformed packet data, resulting in a denial of service against the application. Exploitation requires a victim to open a crafted packet capture file or analyze injected traffic, making this a social-engineering-dependent vector rather than a remotely triggerable flaw. A vendor-released patch is available in versions 4.6.7 and 4.4.17; no public exploit or CISA KEV listing has been identified at time of analysis.

CVE-2026-41986 LOW Monitor

File system logic bypass in Huawei HarmonyOS allows a physically present, unauthenticated attacker to circumvent file system control logic, resulting in limited availability impact on the affected device. CVSS scores this at 2.4 (Low), reflecting the mandatory physical access requirement and constrained availability-only impact with no confidentiality or integrity exposure. No public exploit code exists and the vulnerability is not listed in CISA KEV at time of analysis.

CVE-2026-27145 Go MEDIUM PATCH This Month

Quadratic-complexity denial-of-service in Go's crypto/x509 package allows a network-positioned attacker presenting a certificate with a large DNS Subject Alternative Name list to exhaust CPU on the verifying party. The root cause is that VerifyHostname called strings.Split(host, ".") inside a loop over every DNS SAN entry rather than computing it once, scaling work as O(SANs × hostname_labels). Critically, x509.Verify performs hostname validation before chain building, meaning even untrusted, self-signed certificates trigger the expensive computation - no valid CA-issued certificate is required. No public exploit is identified at time of analysis, and EPSS is 0.00%, consistent with a newly-disclosed algorithmic complexity issue without weaponized tooling.

CVE-2026-5950 MEDIUM PATCH This Month

Resource exhaustion in ISC BIND 9's resolver state machine allows remote unauthenticated attackers to trigger an unbounded resend loop by sending crafted DNS queries that activate bad-server retry conditions, degrading resolver availability. Multiple active release branches are affected across standard and Subscription Edition builds spanning versions 9.18.36 through 9.21.21. No public exploit has been identified and the vulnerability is not listed in CISA KEV; however, the fully network-accessible, zero-authentication attack vector makes every exposed BIND 9 resolver a potential target.

Denial of service in Palo Alto Networks Prisma SD-WAN ION devices allows an unauthenticated attacker with adjacent network access to crash or disrupt the device by sending a specially crafted IPv6 packet. The vulnerability (CWE-606) exists across three active release branches of the ION software, with fixed versions available from Palo Alto Networks. No public exploit code exists and no active exploitation has been identified at time of analysis, with EPSS at 0.03% and SSVC confirming exploitation status as none.

CVE-2026-1519 HIGH POC PATCH This Week

BIND resolver servers performing DNSSEC validation can be forced into excessive CPU consumption when encountering a maliciously crafted DNS zone, resulting in denial of service. The vulnerability affects BIND 9 versions from 9.11.0 through current versions across multiple branches (9.16.50, 9.18.46, 9.20.20, 9.21.19) including BIND Supported Preview Edition variants. The CVSS score of 7.5 indicates high availability impact with network-based exploitation requiring no authentication, though no active exploitation (KEV) or proof-of-concept availability has been indicated in the provided data.
