CVE-2026-77584

Tor before 0.4.9.10 did not reject a CONFLUXLINK cell that arrives on a circuit which already has attached streams. A malicious client could send a RELAYCOMMANDBEGIN before the CONFLUXLINK on the same circuit, attaching an exit stream that would later end up orphan leaving a dangling circuit...

CVE-2026-74359

A flaw was found in the Linux kernel's configfs component. This vulnerability occurs because a memory pointer is not properly cleared after a failure, leading to a 'use-after-free' condition. A local attacker could exploit this by interacting with the affected directory, which could cause memory...

CVE-2026-74345

A flaw was found in the Linux kernel's Soft iWARP siw component, which handles high-performance data transfer. This vulnerability occurs when the system processes a specially crafted connection request, leading to a 'use-after-free' error. An attacker could exploit this to cause a denial of servi...

CVE-2026-64787

A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory management and result in an unexpected process termination. Mitigation Do not process or load untrusted web content with WebKitGTK. In Red Hat Enterprise Linux 7, the following...

Zoo Design Studio: Memory-corruption in memory handling of lib-kcl

A race condition in kcl-lib can result in a use-after-free when accessing environments concurrently. During Vec reallocation, the previous buffer containing Box pointers is freed and replaced. A concurrent getenv operation that has already loaded a pointer to the old buffer may subsequently index...

CVE-2026-63381

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has a use-after-free in buffer.c when evbufferaddbufferreference processes an output buffer whose outtotallen is zero. evbufferfreeallchains frees the initial empty chain without resetting outbuf-first,...

CVE-2026-63380

Libevent is an event notification library. Prior to 2.2.2-alpha, libevent can dereference invalid list pointers in ws.c when evwsnewsession enters its error path after evhttpstartws succeeds but buffereventenablelocking fails. evwsconnectionfree sees a non-null httpserver and unconditionally call...

CVE-2026-74329

A flaw was found in the Linux kernel's watchdog subsystem. When a watchdog device is unregistered, its Power Management PM notifier may not be properly removed. This can lead to a stale pointer being used during a subsequent suspend/resume operation, potentially causing system instability or a...

CVE-2026-74325

A flaw was found in the wifi: mt76 driver within the Linux kernel. This vulnerability occurs because the mt76putvifphylink function improperly deallocates memory for offchannel links. An attacker could exploit this by causing the system to access memory after it has been freed, leading to a...

CVE-2026-18299

GStreamer rtpsbcdepay Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on t...

CVE-2026-74313

A flaw was found in the Linux kernel's vduse component. A race condition in the vdusedevopen function allows a memory object to be freed while still in use. This use-after-free vulnerability could enable a local attacker to cause a system crash denial of service or potentially execute arbitrary...

CVE-2026-74310

A flaw was found in the Linux kernel's vhost/net component. This use-after-free vulnerability occurs due to incorrect handling of zerocopy user buffers, where the system may prematurely complete buffer operations while other parts of the system still hold references to the same memory. This can...
