Security Bulletin: Multiple vulnerabilities addressed in IBM SevOne Network Performance Management for August 2026

Summary IBM SevOne Network Performance Management has addressed these security vulnerabilities in the NMS component including Streaming Telemetry with a Service Pack update. The publication of this security bulletin represents a change in our communication process, not an increase in security...

Unbounded Memory Consumption

Http4s is vulnerable to unbounded memory consumption. The vulnerability is due to HTTP/2 header blocks and CONTINUATION fragments being buffered without a size limit, which allows a remote attacker to keep an incomplete header block open and exhaust heap memory, potentially causing denial of...

CVE-2026-81886

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Windows 64-bit crash-dump dmp64 parser was vulnerable because the Windows dmp64 parser used an input-controlled physical-memory-run PageCount directly as the bound of a per-page allocation loo...

UBUNTU-CVE-2026-81885

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's NE relocation fixup-chain parser was vulnerable because the NE relocation parser followed fixup chains without an active iteration limit or cycle detection. The vulnerability is triggered by...

undertow-core: Undertow: Denial of Service via WebSocket permessage-deflate processing

A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer method using exponential doubling,...

PT-2026-96782

Name of the Vulnerable Software and Affected Versions radare2 versions prior to 6.2.0 Description The Windows 64-bit crash-dump dmp64 parser fails to validate the PageCount of a physical-memory-run against the actual dump size. When opening a specially crafted full-memory Windows crash dump, the...

PT-2026-97003

Name of the Vulnerable Software and Affected Versions icalendar versions 6.1.0 through 7.2.1 Description The vInt.from ical function accepts an attacker-controlled VALARM REPEAT value. Applications requesting alarm times may eagerly expand this value without an application-level limit. This...

CVE-2026-81885: Allocation of Resources Without Limits or Throttling

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's NE relocation fixup-chain parser was vulnerable because the NE relocation parser followed fixup chains without an active iteration limit or cycle detection. The vulnerability is triggered by...

PT-2026-96781

Name of the Vulnerable Software and Affected Versions radare2 versions prior to 6.2.0 Description The NE relocation fixup-chain parser in radare2 lacks an active iteration limit or cycle detection. When opening a specially crafted NE executable where an in-bounds relocation entry points back to...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: ntp (UTSA-2026-090102)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-090102 advisory. ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service memory consumption by sending packets, because memory...

Denial-of-Service (DoS)

Http4s is vulnerable to a Denial-of-Service DoS. The vulnerability is due to HTTP/2 flow-control windows being replenished based on network-received bytes while DATA is stored in an unbounded channel, which allows an attacker to send HTTP/2 request bodies faster than the application consumes them...

io.netty/netty-codec-stomp: Netty: Denial of Service vulnerability in STOMP decoder

A flaw was found in Netty, a network application framework, specifically within the StompSubframeDecoder component. This vulnerability allows a remote attacker to cause a denial of service DoS by sending a large number of small headers. The decoder fails to properly limit the total number or...

CVE-2026-59303

A flaw was found in Spring Cloud Stream where the dynamic destination cache size is not properly bound. This could lead to excessive memory consumption, potentially impacting system resources. An attacker with high privileges and user interaction could exploit this vulnerability over a network to...
