BIG-IP has a vulnerability where an authenticated user of any role may be able to create administrative user accounts through an undisclosed request to Traffic Management User Interface (TMUI).
Impact:
This vulnerability may allow an authenticated attacker with network access to the BIG-IP management interface to escalate privileges by creating administrative accounts on the BIG-IP system. There is no data plane exposure; this is a control plane issue only.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
BIG-IP HTTP/2 Vulnerability – CVE-2026-59762 F5 has disclosed a high-severity BIG-IP vulnerability rated CVSS 7.5.
In simple terms, an unauthenticated attacker could send malicious HTTP/2 requests that consume excessive memory, potentially restarting the TMM process and disrupting applications behind the BIG-IP system.
Affected: BIG-IP virtual servers using an HTTP/2 profile, including affected BIG-IP, BIG-IP Next for Kubernetes, SPK and CNF releases.
What to do: Upgrade to an F5-listed fixed version. If patching cannot be completed immediately, review where HTTP/2 is enabled and restrict unnecessary external exposure. 🔗 Official F5 advisory 🔗 VulniPulse breakdown and affected versions
When an HTTP/2 profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization.
Impact: System performance can degrade until the TMM process is either forced to restart or is manually restarted. This vulnerability allows a remote, unauthenticated attacker to cause a degradation of service that can lead to a denial-of-service (DoS) on the BIG-IP system. There is no control plane exposure; this is a data plane issue only.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
When a BIG-IP is configured with DNS caching (Such as a DNS profile with caching enabled, SSL Orchestrator, Advanced WAF DoS protection), undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
When running in Appliance mode, an authenticated attacker assigned the 'Administrator' role may be able to bypass Appliance mode restrictions on a BIG-IP system.

When an SSL profile is configured on a virtual server on BIG-IP Virtual Edition (VE) without Intel QuickAssist Technology (QAT) or on BIG-IP hardware platforms with the database variable crypto.hwacceleration set to disabled, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A vulnerability exists in BIG-IP systems that may allow an authenticated attacker with administrative access to escalate their privileges. A successful exploit may allow the attacker to cross a security boundary.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
When embedded Packet Velocity Acceleration (ePVA) acceleration is configured, undisclosed local ethernet traffic can cause an increase in ePVA and Traffic Management Microkernel (TMM) resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
When Bidirectional Forwarding Detection (BFD) is configured in Static and Dynamic routing protocols, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to stop processing BFD packets and cause the configured routing protocol to fail over. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
When configured, IP-based access restrictions for httpd do not cover all endpoints, which may allow connections from blocked addresses. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Improper input validation in the UEFI WheaERST module for some Intel(R) reference platforms may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

In the Linux kernel, the following vulnerability has been resolved: nfsd: don't ignore the return code of svcprocregister() Currently, nfsdprocstatinit() ignores the return value of svcprocregister(). If the procfile creation fails, then the kernel will WARN when it tries to remove the entry later. Fix nfsdprocstatinit() to return the same type of pointer as svcprocregister(), and fix up nfsdnetinit() to check that and fail the nfsdnet construction if it occurs. svcprocregister() can fail if the dentry can't be allocated, or if an identical dentry already exists. The second case is pretty unlikely in the nfsdnet construction codepath, so if this happens, return -ENOMEM.
