Title
Krb5: mit krb5 kadmind authenticated memory leak dos in xdr_krb5_tl_data() decode failure
Summary
xdr_krb5_tl_data() in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) does not free partially decoded data on failure, which allows remote authenticated users to cause a denial of service (memory leak in kadmind) via crafted RPC requests that trigger a decode failure.

Title
Krb5: mit krb5 gss-rpc client memory leak on xid mismatch retries
Summary
clnttcp_call() in lib/rpc/clnt_tcp.c in MIT Kerberos 5 (aka krb5) does not free the RPC reply verifier between retries, which allows remote attackers to cause a denial of service (memory leak in GSS-RPC client programs) by injecting RPC replies with mismatched XIDs or by triggering authentication retries.

CVE-2026-112200 (GCVE-0-2026-112200)

Vulnerability from cvelistv5 – Published: 2026-10-29 15:42 – Updated: 2026-11-05 21:26
VLAI
Title
Resource exhaustion from unreleased AR and RPC session on RPC requests with incorrect endianness
Summary
P-Net before 1.0.3 does not release the Application Relationship (AR) and the RPC session when an RPC request is rejected because its data representation has incorrect endianness. The session and its AR remain allocated, so repeated requests exhaust the available sessions. Once they are exhausted the device no longer answers new RPC requests, including Connect, until it is restarted. A remote unauthenticated attacker can use this to cause a denial of service.

CVE-2026-107834 (GCVE-0-2026-107834)

Vulnerability from cvelistv5 – Published: 2026-10-09 17:41 – Updated: 2026-10-13 20:26

Title
OWASP Coraza WAF: Resource exhaustion via deferred file handle accumulation in multipart body processor
Summary
OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. From 3.0.0 until 3.8.0, the multipart loop in internal/bodyprocessors/multipart.go executes defer temp.Close() for every uploaded file part, so each temporary-file descriptor remains open until the complete request returns. An unauthenticated attacker can submit a multipart body containing many minimal file parts and exhaust the process file-descriptor table within the request-body size limit, causing os.CreateTemp failures, MULTIPART_STRICT_ERROR responses, blocked legitimate uploads, and process-wide inability to open files or sockets. This issue is fixed in version 3.8.0.

CVE-2026-107286 (GCVE-0-2026-107286)

Title
Pydantic AI: Concurrency-limited models can keep their slot when a streamed request ends early
Summary
Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From 2.10.0 until 2.53.0, streamed requests made through ConcurrencyLimitedModel or limit_model_concurrency can retain shared concurrency slots because anyio.CapacityLimiter associates an acquired slot with the borrowing task while streaming cleanup can run in a different task. Early stream termination, cancellation, consumer exceptions, or complete stream_text() consumption with debounce_by=0.1 can therefore leave capacity occupied, eventually preventing later requests that share the long-lived limiter from proceeding and causing a denial of service. Agent-level max_concurrency and non-streaming model requests are not affected. This issue is fixed in version 2.53.0.

CVE-2026-104112 (GCVE-0-2026-104112)

Vulnerability from cvelistv5 – Published: 2026-10-09 14:19 – Updated: 2026-10-09 16:45

Title
Missing release of passed file descriptors in illumos nscd allows local users to exhaust kernel memory
Summary
A missing release of resources in the illumos name service cache daemon (nscd) allows a local user to exhaust kernel memory. The nscd door server procedure, switcher() in usr/src/cmd/nscd/nscd_frontend.c, does not close file descriptors that are passed with a door call but not used by the request, and the main nscd door at /var/run/name_service_door accepts passed descriptors from any user in its zone. Because nscd also runs with an unlimited file descriptor limit, an unprivileged local user, including one in a non-global zone, can repeatedly pass a descriptor to its zone's nscd in a door_call() loop, causing the file descriptor table of nscd to grow without bound in kernel memory. This causes a denial of service of nscd and can render processes in all zones on the host unresponsive. The flaw has existed since 2006 (illumos-gate commit cb5caa98), and affects any illumos distribution prior to illumos-gate commit af810a72.

Title
Sssd: sssd: denial of service via race condition in autofs responder
Summary
A flaw was found in SSSD. A local user can trigger a Denial of Service (DoS) by exploiting a race condition in the autofs responder between asynchronous enumeration completion and map invalidation. By repeatedly sending concurrent map enumeration and invalidation requests, an attacker can cause memory to leak, leading to excessive memory consumption that can disrupt or crash the autofs service.

CVE-2026-104035 (GCVE-0-2026-104035)

Vulnerability from cvelistv5 – Published: 2026-10-06 00:12 – Updated: 2026-11-05 15:52
VLAI
Title
Sssd: sssd: denial of service via memory exhaustion in kcm responder
Summary
A flaw was found in SSSD. An issue in the Kerberos Credential Manager (KCM) responder allows a local user to cause a Denial of Service (DoS) by maintaining a persistent connection and repeatedly storing and destroying credentials. Because the service fails to release cached objects from memory when credentials are removed, memory consumption grows continuously, ultimately exhausting available memory and rendering the service unresponsive.

Title
Sssd: sssd: denial of service via memory exhaustion in autofs responder
Summary
A flaw was found in SSSD. In configurations where the autofs responder service is enabled, memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this vulnerability by maintaining an open connection and repeatedly submitting valid requests, leading to memory exhaustion and a Denial of Service (DoS).

If the responder must remain enabled, restrict access to the autofs responder socket to trusted local clients only. Closing long-lived client connections or restarting the responder reclaims the retained memory, but this is operational containment rather than a complete fix. Note that disabling the autofs responder prevents the resolution and mounting of automount maps managed via SSSD, and stopping or restarting SSSD services will briefly interrupt active identity lookups and automount operations."

Mitigation MIT-3
Requirements

Strategy: Language Selection

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
Mitigation
Implementation

It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free resources in a function. If you allocate resources that you intend to free upon completion of the function, you must be sure to free the resources at all exit points for that function including error conditions.

Mitigation MIT-47
Operation Architecture and Design

Strategy: Resource Limitation

  • Use resource-limiting settings provided by the operating system or environment. For example, when managing system resources in POSIX, setrlimit() can be used to set limits for certain types of resources, and getrlimit() can determine how many resources are available. However, these functions are not available on all operating systems.
  • When the current levels get close to the maximum that is defined for the application (see CWE-770), then limit the allocation of further resources to privileged users; alternately, begin releasing resources for less-privileged users. While this mitigation may protect the system from attack, it will not necessarily stop attackers from adversely impacting other users.
  • Ensure that the application performs the appropriate error checks and error handling in case resources become unavailable (CWE-703).
CAPEC-469: HTTP DoS

An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.
