Descripción técnica

In the Linux kernel, the following vulnerability has been resolved: driver core: fix potential NULL pointer dereference in dev_uevent() If userspace reads "uevent" device attribute at the same time as another threads unbinds the device from its driver, change to dev->driver from a valid pointer to NULL may result in crash. Fix this by using READ_ONCE() when fetching the pointer, and take bus' drivers klist lock to make sure driver instance will not disappear while we access it. Use WRITE_ONCE() when setting the driver pointer to ensure there is no tearing.

——0Klever-Go is the Go implementation of the Klever blockchain protocol. Versions 1.7.14 through 1.7.17 are vulnerable to a nil-pointer panic triggered by a protobuf Transaction whose embedded RawData sub-message is omitted. This omission causes RawData to decode to nil. Every transaction gossiped on the Klever-Go P2P network is decoded and validated synchronously inside the libp2p pubsub topic-validator callback, where txVersionChecker.CheckTxVersion dereferences tx.RawData.Version with no nil check. Because the libp2p pubsub callback, the underlying go-libp2p-pubsub validation worker, and Klever's own network/p2p layer install no recover(), the panic propagates and crashes the entire node process. The attacker payload is a 3-byte protobuf message; no validator key, stake, funds, or on-chain account is required, and delivery aimed at enough of the BLS validator set can halt block production, resulting in a chain halt. This issue has been fixed in version 1.7.18.18h CVE-2026-190125.3 MED

——0Consul Community Edition and Consul Enterprise 1.18.0 through 2.0.2 are vulnerable to an authenticated denial of service in the Enterprise-to-Community Edition downgrade path that may allow an authorized caller to crash the Consul server. A caller with config-entry write permission can submit a service-router configuration entry that causes the agent to exit unexpectedly. This vulnerability, CVE-2026-19012, is fixed in Consul 2.0.3 and Consul Enterprise 1.21.17, 1.22.11, and 2.0.3.21h CVE-2026-480977.8 ALT

——0NexTor IP Changer is a command-line tool that leverages the Tor network to periodically rotate a user's IP address. Versions prior to 2.0.0 have a command execution vulnerability due to unsafe use of `shell=True` with commands that rely on executable resolution through the `PATH` environment variable. An attacker controlling the execution environment can place malicious executables such as sudo earlier in the `PATH`, resulting in execution of attacker-controlled code. Version 2.0.0 fixes the issue.21h CVE-2026-452045.5 MED

——2Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger OOB access and kernel null pointer dereference in an error path. Null pointer dereference occurs in an error path of a function running in kernel thread of execution leading to kernel exceptions, platform instability and denial of service.23h CVE-2026-706407.0 ALT

——2llama.cpp builds b1886 through b7445 contain a race condition use-after-free vulnerability in the LLaMA-Android JNI wrapper where bench_1model() and free_1context() lack synchronization, allowing Thread A to operate on freed memory while Thread B concurrently frees the llama_context. Attackers can exploit this by performing heap spray with attacker-controlled data containing a fake vtable to hijack the vtable pointer at offset +0x30, causing llama_batch_allocr::clear() to dereference arbitrary memory and achieve remote code execution.22h CVE-2026-706395.5 MED

——1llama.cpp builds b1886 through b7445 contain a null pointer dereference vulnerability in the LLaMA-Android JNI wrapper where the bench_1model() function fails to validate the model context pointer before dereferencing it. Attackers can supply a malicious, corrupt, or truncated model file to trigger a null context condition, causing a SIGSEGV crash that terminates the Android application process and results in denial of service.22h
