CVE-2026-50018

Hoverfly (open source API simulation tool) prior to version 1.12.8 is vulnerable to denial of service via a goroutine leak in its remote post-serve actions . The root cause is the use of http.DefaultClient without any timeout configuration: when the remote endpoint is unreachable or intentionally...

CVE-2026-50013

Hoverfly (an open-source API simulation/proxy tool by SpectoLabs) is affected by an unsynchronized concurrent map write in its Diff mode . Prior to version 1.12.8 , the AddDiff() function writes to the shared responsesDiff map without a mutex. Because Hoverfly processes proxy requests concurrentl...

CVE-2026-48496

OpenTelemetry eBPF Profiler (versions 0.0.202527 through before 0.0.202622 ) is vulnerable to a denial of service triggered by a local, unprivileged process. The root cause is that the profiler can be induced to open a nonregular mapping file (such as a FIFO), which causes it to block indefinitel...

CVE-2026-48490

ArduinoCore-avr (the source code and configuration files of the Arduino AVR Boards platform) contains a stack-based buffer overflow in its floating-point concatenation path. Versions prior to 1.8.8 are affected. Passing values near the extremes of the float or double range to String::concat(float...

CVE-2026-89476

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending specially crafted duplicate RECONF responses. This action can cause an underflow in the stream-outcnt counter, potentially leading to unexpected system...

CVE-2026-89643

A flaw was found in the Linux kernel's audit subsystem. When fsnotify rules are automatically removed, the system incorrectly manages memory references, leading to a situation where freed memory can be accessed again. This memory corruption vulnerability could allow a local attacker to cause a...

CVE-2026-89626

A flaw was found in the Linux kernel's Human Interface Device HID sensor custom driver. When creating sysfs groups for custom sensor fields, the hidsensorcustomaddattributes function fails to properly clean up previously created groups if an error occurs. This improper resource management could...

CVE-2026-89593

A flaw was found in the Linux kernel's huge page hugetlb subsystem. This vulnerability occurs when a huge page of memory is shared between a parent and a child process. If the parent process unmaps the huge page before the child, the system can incorrectly reduce the count of reserved huge pages...

CVE-2026-89555

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS subsystem. When processing specially crafted Geneve packets through an MPLS multipath setup, a use-after-free vulnerability occurs. This issue arises because a cached header pointer hdr is not reloaded after pskbmaypull...

CVE-2026-89529

A flaw was found in the Linux kernel's svcrdma component, which handles Remote Procedure Call over Remote Direct Memory Access RPC/RDMA Read operations. This vulnerability occurs because the Read list decoder does not properly validate the lengths of incoming data segments. An attacker could send...

CVE-2026-89518

A flaw was found in the Linux kernel's schedext component. Under core scheduling, incorrect assumptions in dispatch kfuncs regarding thisrq can lead to a deadlock. This occurs when an rq lock is acquired on a CPU different from the dispatched rq's, potentially causing the system to become...

CVE-2026-89503

A flaw was found in the Linux kernel's ring-buffer component. A race condition exists in the ringbufferallocreadpage function when it interacts with ringbuffersubbuforderset. This can lead to an incorrect memory allocation where the buffer page's order bpage-order does not match the actual...

CVE-2026-89534

A flaw was found in the Linux kernel's svcrdma module. This vulnerability occurs when the system attempts to handle an RDMA Remote Direct Memory Access address change, and a critical memory allocation fails. This can lead to a 'use-after-free' error, where the system tries to access memory that h...

CVE-2026-89510

A flaw was found in the Linux kernel's RDMA/cxgb4 component. This vulnerability occurs when the c4iwremove function frees a device while its registration work regwork is still pending or actively running. This timing issue can lead to the c4iwregisterdevice function attempting to access memory th...

CVE-2026-89494

A flaw was found in ocfs2, a component of the Linux kernel. A remote attacker, by sending a specially crafted Distributed Lock Manager DLM migration message, could exploit a lack of validation in the dlmmiglockreshandler. This flaw allows for an out-of-bounds write to the heap, potentially leadin...

CVE-2026-80788

A flaw was found in the Linux kernel's nvmet-tcp component. A remote attacker can send a specially crafted command with an oversized Scatter-Gather List SGL allocation. This can lead to an excessive memory allocation, triggering a kernel warning. On systems configured to panic on warnings, this...

CVE-2026-89727

CVE-2026-89727 affects the Linux kernel KVM arm64 GICv2 implementation. In vgic_v2_deactivate(), a guest-written INTID is passed directly to vgic_get_vcpu_irq(), where a failed lookup triggers WARN_ON_ONCE()—treated as a "can't happen" condition. Since GICv2 has no LPIs, any INTID outside the SGI...

EUVD-2026-76626

In the Linux kernel, the following vulnerability has been resolved: NFS: fix delegationhashtable leak when nfs4servercommonsetup fails nfs4servercommonsetup allocates server-delegationhashtable first, but server-destroy - the only path that frees the table via nfs4destroyserver - is not assigned...

CVE-2026-89714

This Linux kernel vulnerability affects the NFSv4 client subsystem. The root cause is a memory leak of server->delegation_hash_table (4 KiB per attempt with the default delegation watermark) when nfs4_server_common_setup() fails at an intermediate step (is_ds_only_client(), nfs4_init_session()...

EUVD-2026-76611

In the Linux kernel, the following vulnerability has been resolved: nfsd: validate symlink target length in NFSv4 CREATE nfsd4decodecreate accepts an unbounded crdatalen from the wire for NF4LNK symlink targets, allowing a client to force a kmalloc of up to the maximum RPC payload size several Mi...
