Denial of service in Silicon Labs SiSDK v2026.6.0 and earlier affects EFR32MG24 and EFR32MG26 wireless SoCs running concurrent multiprotocol Zigbee and Thread. Under high network traffic loads, ACK packets are dropped, causing the device networking stack to fail and rendering the IoT endpoint unresponsive. No public exploit has been identified and active exploitation has not been confirmed by CISA KEV, but the patch is available from the vendor.
MySQL Connector/ODBC version 26.7.0 exposes a local denial-of-service condition that allows an unauthenticated attacker with logon access to the host to cause a complete hang or repeatable crash of the connector, disrupting dependent applications. Exploitation requires human interaction from a third party (UI:R), constraining the realistic attack surface to insider threat or socially engineered scenarios on the affected host. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog; availability is the sole impact dimension - confidentiality and integrity are unaffected.
Denial of service in Calix GigaSpire 26.1.0 is reachable remotely through manipulation of the traceroute.cmd diagnostic endpoint, causing availability disruption to the affected device. The root cause is improper resource handling (CWE-404) within the traceroute function, which fails to properly release resources under adversarial input. A proof-of-concept exploit has been publicly disclosed; no vendor patch or advisory is available as the vendor did not respond to coordinated disclosure.
Denial of service in Calix GigaSpire 26.1.0 is achievable remotely by low-privileged attackers who manipulate the sessionKey argument within the utilities_configurationsave.cgi endpoint of the Web Management Interface, causing improper resource release (CWE-404) and disrupting device availability. The affected product is a residential and SMB broadband gateway deployed by ISPs. Published exploit code exists (E:P in the CVSS 4.0 vector), and no vendor patch has been confirmed - the vendor did not respond to the coordinated disclosure.
Denial of service in Open5GS 2.7.6 and earlier allows network-adjacent attackers with low-privilege Diameter Gx peer access to crash the Session Management Function (SMF) by sending a malformed Credit-Control-Answer (CCA) message to the smf_gx_cca_cb handler. A publicly available proof-of-concept crash sample (SMF.crashes.zip) confirms exploitability; the absence of a CISA KEV listing indicates no confirmed widespread threat-actor exploitation has been reported. In 5G/4G core network deployments, an SMF crash disrupts session management for all connected user equipment, making this a higher operational risk than the CVSS medium score alone suggests.
Denial of service in Open5GS HSS (Home Subscriber Server) versions 2.7.0 through 2.7.6 is triggered remotely by manipulating the Session-Id argument processed by the fd_msg_sess_get function, causing the HSS service to fail. Low-privileged network access to the Diameter interface is sufficient to exploit this flaw, and a proof-of-concept packet capture (HSS_ULR_error_poc.pcapng.zip) has been publicly released via GitHub. No active exploitation has been confirmed in CISA KEV, but the public POC materially lowers the barrier for targeted attacks against private LTE/5G deployments running this stack.
Denial of service in lmammino oidc-authorizer 0.4.0 can be triggered remotely by submitting a crafted value for the authorization_token argument processed by the parse_token_from_header function in the Authorization Header Parsing component. Any service using this Rust library to validate OIDC tokens via the HTTP Authorization header is exposed to availability disruption without requiring authentication. A public proof-of-concept exploit has been disclosed, though the vulnerability is not confirmed as actively exploited in CISA KEV.
Partial denial-of-service exposure in Oracle Agile Engineering Data Management 6.2.1 allows a local, low-privileged attacker to degrade availability of the Install component when a separate user interacts with the system. The CVSS 3.1 base score of 2.8 reflects the constrained impact: only availability is affected, no confidentiality or integrity loss occurs, and exploitation is bounded by local access and mandatory human interaction from a third party. No public exploit code or active exploitation has been identified at time of analysis.
Oracle Inventory Management within Oracle E-Business Suite 12.2.3 through 12.2.15 is susceptible to a local, highly constrained partial denial-of-service condition affecting only availability. Exploitation requires an already highly privileged attacker with direct logon access to the underlying infrastructure hosting the application, combined with high attack complexity, making successful exploitation extremely difficult in practice. No public exploit code or active exploitation has been identified; the CVSS score of 1.9 reflects the minimal real-world risk posed by this vulnerability.
Denial-of-service in MySQL Connector/J 9.7.0-9.7.1 allows an unauthenticated remote attacker to crash or indefinitely hang the connector process via multiple protocols, contingent on human interaction from a victim. Oracle disclosed this in the July 2026 Critical Patch Update (CPU), rating it CVSS 6.5. No public exploit code and no CISA KEV listing have been identified at time of analysis, suggesting risk is currently theoretical rather than actively weaponized.
Denial of service in Silicon Labs SiSDK v2026.6.0 and earlier affects EFR32MG24 and EFR32MG26 wireless SoCs running concurrent multiprotocol Zigbee and Thread. Under high network traffic loads, ACK packets are dropped, causing the device networking stack to fail and rendering the IoT endpoint unresponsive. No public exploit has been identified and active exploitation has not been confirmed by CISA KEV, but the patch is available from the vendor.
