Name of the Vulnerable Software and Affected Versions HdrHistogram versions prior to 2.2.3 Description An issue exists in the decodeFromCompressedByteBuffer function within the org.HdrHistogram.AbstractHistogram class. Local manipulation of the lengthOfCompressedContents argument can lead to...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS due to the lack of an upper bound on memory allocation for unacknowledged WebSocket PING frames. An attacker can cause memory exhaustion by sending a rapid sequence of PING messages from a malicious server. Details...

CVE-2026-11586

By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by flooding curl with rapid, sequential PING messages...

SUSE CVE-2026-53335

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lrusort: handle ctx allocation failure DAMONLRUSORT allocates the damonctx object for its kdamond in its init function. damonlrusortenabledstore wrongly assumes the allocation will always succeed once tried. If the...

EUVD-2026-41417

Eclipse Wakaama before snapshot/2026-05-26 contains an unbounded memory allocation vulnerability in the CoAP Block1 handler within coap/block.c that allows unauthenticated remote attackers to exhaust server memory by sending a sequence of Block1 PUT requests with incrementing block numbers...

HdrHistogram: HdrHistogram: Denial of Service via uncontrolled memory allocation

A flaw was found in HdrHistogram. A local attacker can exploit a vulnerability in the decodeFromCompressedByteBuffer function by manipulating the lengthOfCompressedContents argument. This manipulation leads to uncontrolled memory allocation, which can result in a Denial of Service DoS condition,...

netty: io.netty/netty-codec-compression: io.netty/netty-codec: Netty: Denial of Service via excessive memory allocation in LZ4FrameDecoder

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted LZ4 compressed data stream. This can cause the Lz4FrameDecoder to allocate a large amount of memory up to 32 MB per block before...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

CVE-2026-56150

MODE C: CVE-2026-56150 affects Elastic Fleet Server via Allocation of Resources Without Limits or Throttling (upload endpoint memory exhaustion). Multiple connected sources describe the vulnerability in Fleet Server's internal API packages and uploader, enabling an attacker to exhaust RAM and pot...

CVE-2026-53335

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lrusort: handle ctx allocation failure DAMONLRUSORT allocates the damonctx object for its kdamond in its init function. damonlrusortenabledstore wrongly assumes the allocation will always succeed once tried. If the...

UBUNTU-CVE-2026-53335

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lrusort: handle ctx allocation failure DAMONLRUSORT allocates the damonctx object for its kdamond in its init function. damonlrusortenabledstore wrongly assumes the allocation will always succeed once tried. If the...

UBUNTU-CVE-2026-53329

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Use kreallocarray in dalvectorreserve Why & How dalvectorreserve computes the allocation size as "capacity vector-structsize" using uint32t arithmetic, which can silently wrap to a small value on overflow. This...

CVE-2026-14330

CVE-2026-14330 describes an issue in Pipewire’s PulseAudio protocol server, where multiple unbounded alloca() calls can cause a stack overflow. The affected component is the PulseAudio protocol server within Pipewire. Root cause: unbounded alloca() usage leading to potential stack overflow. Accor...

EUVD-2026-40968

In the Linux kernel, the following vulnerability has been resolved: mm/damon/reclaim: handle ctx allocation failure Patch series "mm/damon/reclaim,lrusort: handle ctx allocation failures". DAMONRECLAIM and DAMONLRUSORT could dereference NULL pointers if their damonctx object allocations fail. The...

CVE-2026-53334

In the Linux kernel, the following vulnerability has been resolved: mm/damon/reclaim: handle ctx allocation failure Patch series "mm/damon/reclaim,lrusort: handle ctx allocation failures". DAMONRECLAIM and DAMONLRUSORT could dereference NULL pointers if their damonctx object allocations fail. The...

CVE-2026-53335 mm/damon/lru_sort: handle ctx allocation failure

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lrusort: handle ctx allocation failure DAMONLRUSORT allocates the damonctx object for its kdamond in its init function. damonlrusortenabledstore wrongly assumes the allocation will always succeed once tried. If the...

CVE-2026-53334

The CVE-2026-53334 issue affects the Linux kernel DAMON subsystem, specifically mm/damon/reclaim and mm/damon/lru_sort. The root cause is a failure to handle damon_ctx allocations: if the kdamond damon_ctx allocation fails, code may dereference a NULL ctx in damon_commit_ctx(), leading to potenti...
