A vulnerability in the UDP processing code of Cisco IOS 15.1, 15.2, and 15.4 and IOS XE 3.14 through 3.18 could allow an unauthenticated, remote attacker to cause the input queue of an affected system to hold UDP packets, causing an interface queue wedge and a denial of service (DoS) condition. The vulnerability is due to Cisco IOS Software application changes that create UDP sockets and leave the sockets idle without closing them. An attacker could exploit this vulnerability by sending UDP packets with a destination port of 0 to an affected device. A successful exploit could allow the attacker to cause UDP packets to be held in the input interfaces queue, resulting in a DoS condition. The input interface queue will stop holding UDP packets when it receives 250 packets. Cisco Bug IDs: CSCup10024, CSCva55744, CSCva95506.

brace-expansion: Zero-step sequence causes process hang and memory exhaustion

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., `{1..2..0}`) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to `expand()` to ensure a step value of `0` is not used.

Denial of Service via Uncontrolled Resource Consumption on PowerChute Web Admin

CWE-400 Uncontrolled Resource Consumption vulnerability exists that could cause excessive troubleshooting zip file creation and denial of service when a Web Admin user floods the system with POST /helpabout requests.

Possible DoS via SQL Box

A vulnerability in the SQL Box in the admin interface of OTRS leads to an uncontrolled resource consumption leading to a DoS against the webserver. will be killed by the systemThis issue affects OTRS:  * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.3.X

libgphoto2 has memory leak in ptp_unpack_Sony_DPD() secondary enumeration list in ptp-pack.c

libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have a memory leak in `ptp_unpack_Sony_DPD()` in `camlibs/ptp2/ptp-pack.c` (lines 884–885). When processing a secondary enumeration list (introduced in 2024+ Sony cameras), the function overwrites dpd->FORM.Enum.SupportedValue with a new calloc() without freeing the previous allocation from line 857. The original array and any string values it contains are leaked on every property descriptor parse. Commit 404ff02c75f3cb280196fc260a63c4d26cf1a8f6 fixes the issue.

Memory corruption when using JavaScript Text Segmentation

When segmenting specially crafted text, segmentation would corrupt memory leading to a potentially exploitable crash. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6.

OpenClaw < 2026.3.31 - Resource Consumption via Unauthorized Telegram Audio Preflight Transcription

OpenClaw before 2026.3.31 contains a resource consumption vulnerability in Telegram audio preflight transcription that allows unauthorized group senders to trigger transcription processing. Attackers can exploit insufficient allowlist enforcement to cause resource or billing consumption by initiating audio preflight operations before authorization checks are applied.

Improper Resource Release Causing Denial of Service in Dell PowerScale OneFS

Dell PowerScale OneFS, versions prior to 9.12.0.0, contains an improper resource shutdown or release vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to denial of service.

Leaking file descriptors from the fork server

Leaking of file descriptors from the fork server to web content processes could allow for privilege escalation attacks. This vulnerability was fixed in Firefox 137 and Thunderbird 137.

Unsolicited File Download, Disk Space Exhaustion, and Credential Leakage via mailbox:/// Links

A crafted HTML email using mailbox:/// links can trigger automatic, unsolicited downloads of .pdf files to the user's desktop or home directory without prompting, even if auto-saving is disabled. This behavior can be abused to fill the disk with garbage data (e.g. using /dev/urandom on Linux) or to leak Windows credentials via SMB links when the email is viewed in HTML mode. While user interaction is required to download the .pdf file, visual obfuscation can conceal the download trigger. Viewing the email in HTML mode is enough to load external content. This vulnerability was fixed in Thunderbird 128.11.1 and Thunderbird 139.0.2.

Denial-of-service due to out-of-memory in the Graphics: WebRender component

Denial-of-service due to out-of-memory in the Graphics: WebRender component. This vulnerability was fixed in Firefox 142, Firefox ESR 140.2, Thunderbird 142, and Thunderbird 140.2.

JavaScript alerts could impede UI interaction or allow denial of service attacks

Malicious scripts utilizing repetitive JavaScript alerts could prevent client user interaction in some scenarios and allow for denial of service attacks. This vulnerability was fixed in Firefox for iOS 142.

Malicious scripts could spam popups for denial of service attacks

Malicious scripts could bypass the popup blocker to spam new tabs, potentially resulting in denial of service attacks. This vulnerability was fixed in Firefox for iOS 142.

Directus Affected by GraphQL Alias Amplification Denial-of-Service Due to Missing Query Cost/Complexity Limits

Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, Directus' GraphQL endpoints (/graphql and /graphql/system) did not deduplicate resolver invocations within a single request. An authenticated user could exploit GraphQL aliasing to repeat an expensive relational query many times in a single request, forcing the server to execute a large number of independent complex database queries concurrently, multiplying database load linearly with the number of aliases. The existing token limit on GraphQL queries still permitted enough aliases for significant resource exhaustion, while the relational depth limit applied per alias without reducing the total number executed. Rate limiting is disabled by default, meaning no built-in throttle prevented this from causing CPU, memory, and I/O exhaustion that could degrade or crash the service. Any authenticated user, including those with minimal read-only permissions, could trigger this condition. This vulnerability is fixed in 11.17.0.

Denial of Service via Unauthenticated BLE Connection

An issue in Hero Motocorp Vida V1 Pro 2.0.7 allows a local attacker to cause a denial of service via the BLE component

platform/x86/amd: Fix memory leak in wbrf_record()

In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: Fix memory leak in wbrf_record() The tmp buffer is allocated using kcalloc() but is not freed if acpi_evaluate_dsm() fails. This causes a memory leak in the error path. Fix this by explicitly freeing the tmp buffer in the error handling path of acpi_evaluate_dsm().
