CVE-2026-77384 libp2p: Circuit relay v2 server reservation refresh leaks abort listeners and allows remote resource exhaustion

libp2p is a JavaScript implementation of the libp2p networking stack. Prior to version 4.2.9, the reservation refresh path in reservation-store.ts reuses the same retimeableSignal but unconditionally registers another abort listener on every refresh. As a result, a remote peer can repeatedly send...

CVE-2026-74721

A flaw was found in the Linux kernel's accel/amxdna component. Specifically, an error in the amdxdnainsertpages function causes system resources to be released too early. This premature release can lead to a critical error when the system later attempts to free the same resources, resulting in a...

CVE-2026-74713

A flaw was found in the Linux kernel's vhostiotlb module. Non-retiring tables within this module can continue to allocate entries even after reaching their configured limits. This allows a local attacker or a malicious guest operating system to trigger a continuous stream of IOTLB updates, leadin...

CVE-2026-74696

A flaw was found in the Linux kernel's TCP Fast Open TFO implementation. During SOREUSEPORT listener migration, the system incorrectly accounts for pending TCP Fast Open requests. This can lead to a Denial of Service DoS by allowing an excessive number of Fast Open requests, potentially exhaustin...

pyasn1: pyasn1: Denial of Service via crafted ASN.1 REAL values

A remote attacker can exploit this by providing specially crafted BER/CER/DER-encoded ASN.1 data with a large exponent in the REAL value. When the application subsequently prints, logs, compares, or performs arithmetic on the decoded value, this can cause excessive CPU and memory consumption,...

CVE-2026-74623

A flaw was found in the Linux kernel's atlantic network driver. When a network interface using this driver is deinitialized while under transmit TX or XDPTX load, certain transmit buffers are not properly released. This oversight leads to a memory leak, which can prevent the proper shutdown of...

CVE-2026-78385

RansomLook contains an insufficient resource validation flaw in its analysis PDF generation functionality. Analysis documents are converted from Markdown to HTML and rendered via WeasyPrint . Prior to the fix, WeasyPrint's default URL fetcher resolved resource references without restrictions, all...

CVE-2026-78385 RansomLook Analysis PDF Generation Allows Server-Side Request Forgery and Arbitrary Local File Access

RansomLook contains insufficient resource validation in the analysis PDF generation functionality. Analysis documents are converted from Markdown to HTML and passed to WeasyPrint for PDF rendering. Prior to the fix, WeasyPrint used its default URL fetcher, allowing resource references contained i...

CVE-2026-76842

CVE-2026-76842 affects the Mercado Pago Node.js SDK (through 3.4.0 ). The payment, paymentRefund, advancedPayment, and disbursementRefund clients interpolate caller-supplied identifiers into API request paths via template literals without percent-encoding , so URL-structural characters (dot-dot, ...

CVE-2026-42493

A flaw was found in Xen's x86 shadow paging functionality. Operations within this feature can consume excessive resources, potentially leading to a Denial of Service DoS on the affected system. This functionality has been deprecated due to its operational cost and inherent security risks...

CVE-2026-74719

A flaw was found in the Linux kernel's Server Message Block SMB over Remote Direct Memory Access RDMA SMC protocol implementation. A remote attacker, by sending a duplicate link confirmation or addition request, can cause a memory leak. This occurs because the system overwrites an existing memory...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fixed the error path for FRMR set pinned push operations. Added functionality to destroy FRMR handles in case the push operation to the pool fails. This prevents resource leaks if the pool page allocation fails...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: i2c: imx: Marking the I2C adapter as suspended when the hardware is powered down. On some i.MX platforms, certain I2C client drivers maintain a periodic workqueue that continues to trigger I2C transfers. During system...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Rejects adapter interrupt forwarding if it is already enabled. The MPCIFC instruction does not allow registering adapter interrupts without first unregistering them. Therefore, any request to enable interrupt...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbdev: imxfb: Unnecessary releasememregion has been removed. The unnecessary releasememregion was removed from the error path to prevent the memregion from being released twice, which could lead to resource leaks or other...
