CVSS v3.1 |
| cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.43.4, negative chunk-size in chunked Transfer-Encoding causes unbounded memory allocation and process crash. The ChunkedDecoder::read_payload function in cpp-httplib (httplib.h) parses the chunk-size field of HTTP chunked transfer encoding using std::strtoul(). Per the C standard (§7.22.1.4), strtoul silently accepts a leading minus sign, performing unsigned wrap-around: strtoul("-2", …, 16) returns ULONG_MAX − 1 (0xFFFFFFFFFFFFFFFE). The library's only guard (line 12833) rejects ULONG_MAX (the result of "-1"), but any other negative value such as "-2" passes validation. The resulting near-maximum value is stored in chunk_remaining and controls how many bytes the server's read loop consumes from the network. This vulnerability is fixed in 0.43.4. |
| Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.17, a remote, unauthenticated denial-of-service vulnerability in Batch.Decompress (data/batch/batch.go) allows any peer that participates in a topic served by MultiDataInterceptor to allocate multi-gigabyte heaps on the receiving node from a sub-50 KiB gossip payload. A single packet is sufficient to OOM-kill a validator with conventional memory provisioning. Fleet-wide application affects chain liveness. This vulnerability is fixed in 1.7.17. |
| In getComponentName of MediaButtonReceiverHolder.java, there is a possible desync in persistence due to resource exhaustion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| Nanobot prior to version 0.2.1 contains a denial of service vulnerability in the Matrix channel media download handler that allows authenticated room members to exhaust process memory and bandwidth by sending media events with missing or invalid size metadata. Attackers can send multiple concurrent Matrix media events with omitted or invalid declared sizes to trigger simultaneous large media downloads that fully materialize response bodies before post-download rejection, consuming process resources until service degradation occurs. |
| OOM error is possible while attempting to add infinite amount of functions to Function Registry.
Affected Spring Products and Versions:
Spring Cloud Function 3.2.x: versions prior to 3.2.16
Spring Cloud Function 4.1.x: versions prior to 4.1.10
Spring Cloud Function 4.2.x: versions prior to 4.2.6
Spring Cloud Function 4.3.x: versions prior to 4.3.3
Spring Cloud Function 5.0.x: versions prior to 5.0.2
Older, unsupported versions are also affected. |
| Apache Fluss versions prior to 0.9.1 configure the Netty LengthFieldBasedFrameDecoder with Integer.MAX_VALUE as the maximum frame length, allowing unauthenticated remote attackers to exhaust JVM heap memory on TabletServer and CoordinatorServer by sending specially crafted frame headers, resulting in denial of service.
This issue affects Apache Fluss (incubating): 0.8.0 and 0.9.0.
Users are recommended to upgrade to version 0.9.1, which fixes the issue. |
| The TIFF decoder does not place a limit on the size of PackBits-compressed data. A maliciously-crafted image can exploit this to cause a small image (both in terms of pixel width/height and encoded size) to make the decoder decode large amounts of compressed data. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: split transactions in dio completion to avoid credit exhaustion
During ocfs2 dio operations, JBD2 may report warnings via following
call trace:
ocfs2_dio_end_io_write
ocfs2_mark_extent_written
ocfs2_change_extent_flag
ocfs2_split_extent
ocfs2_try_to_merge_extent
ocfs2_extend_rotate_transaction
ocfs2_extend_trans
jbd2__journal_restart
start_this_handle
output: JBD2: kworker/6:2 wants too many credits credits:5450 rsv_credits:0 max:5449
To prevent exceeding the credits limit, modify ocfs2_dio_end_io_write() to
handle extents in a batch of transaction.
Additionally, relocate ocfs2_del_inode_from_orphan(). The orphan inode
should only be removed from the orphan list after the extent tree update
is complete. This ensures that if a crash occurs in the middle of extent
tree updates, we won't leave stale blocks beyond EOF.
This patch also changes the logic for updating the inode size and removing
orphan, making it similar to ext4_dio_write_end_io(). Both operations are
performed only when everything looks good.
Finally, thanks to Jans and Joseph for providing the bug fix prototype and
suggestions. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: pcrypt - Fix handling of MAY_BACKLOG requests
MAY_BACKLOG requests can return EBUSY. Handle them by checking
for that value and filtering out EINPROGRESS notifications. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Limit BO list entry count to prevent resource exhaustion
Userspace can pass an arbitrary number of BO list entries via the
bo_number field. Although the previous multiplication overflow check
prevents out-of-bounds allocation, a large number of entries could still
cause excessive memory allocation (up to potentially gigabytes) and
unnecessarily long list processing times.
Introduce a hard limit of 128k entries per BO list, which is more than
sufficient for any realistic use case (e.g., a single list containing all
buffers in a large scene). This prevents memory exhaustion attacks and
ensures predictable performance.
Return -EINVAL if the requested entry count exceeds the limit

| IBM WebSphere Application Server - Liberty 19.0.0.7 through 26.0.0.5 and IBM WebSphere Application Server 9.0, and 8.5 and WebSphere Application Server Liberty are vulnerable to a denial of service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. |
| A flaw was found in OpenShift Container Platform. Completed pods with restartPolicy: Never do not count toward ResourceQuota pod limits, and Kubernetes events are not quota-scoped. A non-privileged user who can create pods in a namespace can exploit this to generate a large volume of events that accumulate in etcd, causing API server performance degradation across the cluster. |
| An uncontrolled allocation of resources without limits or throttling in the e-mail handling in OTRS allows excessive allocation which may lead to the abortion of the webserver.This issue affects OTRS:
* 8.0.X
* 2023.X
* 2024.X
* 2025.X
* 2026.X before 2026.4.X
Please note that ((OTRS)) Community Edition 6.x, OTRS 7.x and products based on the ((OTRS)) Community Edition also very likely to be affected |
| opentelemetry-java is the Java implementation of the OpenTelemetry API for recording telemetry, and SDK for managing telemetry recorded by the API. Prior to 1.62.0, a vulnerability affects the baggage propagation implementation in opentelemetry-api and opentelemetry-extension-trace-propagators. Parsing oversized baggage causes unbounded memory allocation and CPU consumption. Because baggage is automatically re-injected into every outgoing request, the effect can fan out to downstream services that never received the original malicious request. This vulnerability is fixed in 1.62.0. |
| Volcano is a Kubernetes-native batch scheduling system. Prior to v1.14.2, v1.13.3, and v1.12.4, the Volcano webhook server does not enforce a size limit on incoming HTTP request bodies. Any in-cluster pod that can reach the webhook endpoint may send an arbitrarily large request body, potentially causing the webhook server to be killed by OOM. All Volcano deployments with the webhook server exposed to in-cluster traffic are affected. This vulnerability is fixed in v1.14.2, v1.13.3, and v1.12.4. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conncount: increase the connection clean up limit to 64
After the optimization to only perform one GC per jiffy, a new problem
was introduced. If more than 8 new connections are tracked per jiffy the
list won't be cleaned up fast enough possibly reaching the limit
wrongly.
In order to prevent this issue, only skip the GC if it was already
triggered during the same jiffy and the increment is lower than the
clean up limit. In addition, increase the clean up limit to 64
connections to avoid triggering GC too often and do more effective GCs.
This has been tested using a HTTP server and several
performance tools while having nft_connlimit/xt_connlimit or OVS limit
configured.
Output of slowhttptest + OVS limit at 52000 connections:
slow HTTP test status on 340th second:
initializing: 0
pending: 432
connected: 51998
error: 0
closed: 0
service available: YES |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.12.1, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing large XMP metadata, possibly with lots of unnecessary elements. This vulnerability is fixed in 6.12.1. |
| ABB, Phoenix Contact, Schneider Electric, Siemens, WAGO - Programmable Logic Controllers, multiple versions. Researchers have found some controllers are susceptible to a denial-of-service attack due to a flood of network packets. |
| Uncontrolled resource consumption in the Wireless Control Module (WCM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with write access to the in-vehicle network to permanently immobilize the motorcycle. The WCM enforces a brute-force lockout on the immobilizer authentication algorithm, but the lockout counter is reachable by any unauthenticated message, has no session binding, and does not reset on power cycle. An attacker can deliberately trip the lockout with a small number of crafted frames, leaving the bike un-startable until dealer service. Specific thresholds have been withheld pending vendor remediation. |
| IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.4 is vulnerable to a denial of service when a specially crafted query is run with range partitioned tables. |
