CVE-2026-90088 Bluetooth: RFCOMM: Validate MTU in rfcomm_apply_pn() to prevent infinite loop

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: Validate MTU in rfcommapplypn to prevent infinite loop rfcommapplypn accepts the MTU value from a remote PN Parameter Negotiation frame without checking for zero. When the remote peer sends an MTU of zero, d-mt...

CVE-2026-90053 net/sched: sch_htb: limit htb_classify inner-class filter hops

In the Linux kernel, the following vulnerability has been resolved: net/sched: schhtb: limit htbclassify inner-class filter hops htbclassify follows each filter-selected inner class by switching to cl-filterlist, but never bounds the number of hops. A filter on an inner class can point back to...

CVE-2026-90053

CVE-2026-90053 is a vulnerability in the Linux kernel 's HTB qdisc (net/sched: sch_htb). The function htb_classify() follows filter-selected inner classes without bounding the traversal depth, so a self-referencing or cyclic inner-class u32 filter creates an infinite loop in the packet classifica...

Denial of Service (DoS)

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Denial of Service DoS through the FinalizationRegistry process. An attacker can cause the host event loop to be blocked for an unbounded period by...

CVE-2026-92596

A flaw was found in Nodemailer's addressparser component. This vulnerability, due to quadratic time complexity, allows a remote attacker to cause a Denial of Service DoS. By sending a specially crafted email with a large, comma-separated list of addresses, the attacker can block the Node.js event...

Security Bulletin: IBM Financial Transaction Manager is impacted by multiple vulnerabilities in RedHat Proxy for Kubernetes RBAC authorization

Summary IBM Financial Transaction Manager for RedHat OpenShift has addressed the following vulnerabilities. Vulnerability Details CVEID:CVE-2026-33814 DESCRIPTION: When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a...

unbound: Unbound: Denial of Service via continuous queries on TCP/DoT connection

A flaw was found in Unbound. A malicious actor can exploit a vulnerability in the TCP/DoT reading procedure, which lacks a limit on consecutive reads. By continuously streaming distinct uncached names over a TCP/DoT connection, an attacker can monopolize a worker's event loop. This can lead to a...
