Cybersecurity researchers have disclosed multiple critical security vulnerabilities in Chaos Mesh that, if successfully exploited, could lead to cluster takeover in Kubernetes environments. "Attackers need only minimal in-cluster network access to exploit these vulnerabilities, execute the platform's fault injections (such as shutting down pods or disrupting network communications), and perform

Apple on Monday backported fixes for a recently patched security flaw that has been actively exploited in the wild. The vulnerability in question is CVE-2025-43300 (CVSS score: 8.8), an out-of-bounds write issue in the ImageIO component that could result in memory corruption when processing a malicious image file. "Apple is aware of a report that this issue may have been exploited in an

A team of academics from ETH Zürich and Google has discovered a new variant of a RowHammer attack targeting Double Data Rate 5 (DDR5) memory chips from South Korean semiconductor vendor SK Hynix. The RowHammer attack variant, codenamed Phoenix (CVE-2025-6202, CVSS score: 7.1), is capable of bypassing sophisticated protection mechanisms put in place to resist the attack. "We have proven that

A vulnerability in Apache Fory allows a remote attacker to cause a Denial of Service (DoS). The issue stems from the insecure deserialization of untrusted data. An attacker can supply a large, specially crafted data payload that, when processed, consumes an excessive amount of CPU resources during the deserialization process. This leads to CPU exhaustion, rendering the application or system using the Apache Fory library unresponsive and unavailable to legitimate users. Users of Apache Fory are strongly advised to upgrade to version 0.12.2 or later to mitigate this vulnerability. Developers of libraries and applications that depend on Apache Fory should update their dependency requirements to Apache Fory 0.12.2 or later and release new versions of their software.

### Summary A use-after-free (UAF) vulnerability in Envoy's DNS cache causes abnormal process termination. Envoy may reallocate memory when processing a pending DNS resolution, causing list iterator to reference freed memory. ### Details The vulnerability exists in Envoy's Dynamic Forward Proxy implementation starting from version v1.34.0. The issue occurs when a completion callback for a DNS resolution triggers new DNS resolutions or removes existing pending resolutions. This condition may occur in the following configuration: 1. Dynamic Forwarding Filter is enabled. 2. `envoy.reloadable_features.dfp_cluster_resolves_hosts` runtime flag is enabled. 3. The Host header is modified between the Dynamic Forwarding Filter and Router filters. ### Impact Denial of service due to abnormal process termination. ### Attack vector(s) Request to Envoy configured as indicated above. ### Patches Users should upgrade to v1.35.1 or v1.34.5. ### Workaround Set the `envoy.reloadable_features.df...
