One Is Not Enough: The Untold Story of Multiple Security Patches for One Vulnerability

Security patches SPs are the main mechanism for fixing software vulnerabilities, yet a single vulnerability is not always resolved by a single patch: fixes may be completed incrementally, propagated across maintained branches, or replicated across related repositories. When patch records are...

SUSE CVE-2026-72428

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix stack slot index in nospec checks checkstackwritefixedoff computes the byte slot for a fixed-offset stack write as -off - 1, and records each written byte in slottype with slot - i % BPFREGSIZE. The Spectre v4 sanitizati...

From Silicon to Boot Code: Extending Automated Program Repair to Firmware-Layer Security Workarounds

Automated program repair APR research has been constrained to design time. Current techniques localize and fix bugs in RTL or HLS designs before a chip reaches production. Once a hardware vulnerability surfaces post-silicon, the patch must be manually generated: existing automation addresses patc...

SUSE CVE-2026-72236

In the Linux kernel, the following vulnerability has been resolved: s390/perfcpumcf: Add missing arrayindexnospec to hwperfeventinit ev variable is userspace controlled via event-attr.config and used as an array index after bounds checking, but without speculation barriers. Add the missing...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

Intel’s microprocessor generations 6 to 8 are affected by a new Spectre variant that can bypass the retpoline mitigation mechanism in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to execute arbitrary speculative code under certain...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.11.x. The kernel/bpf/verifier.c file contains unwanted out-of-bounds speculation during pointer arithmetic operations, which allows for side-channel attacks that circumvent Spectre mitigations and extract sensitive information from kern...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: arm64: errata: Add missing sentinel entries to Spectre-BHB MIDR arrays The commit a5951389e58d “arm64: errata: Add newer ARM cores to the spectrebhbloopaffected lists” added some additional CPUs to the Spectre-BHB workaround. Thi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: s390/diag: Add a missing arrayindexnospec call to memtopgetpagecount. The level field is controlled by the user space and is used to read from an array. Add the missing arrayindexnospec call to prevent speculative execution...

Cybersecurity researchers have disclosed details of a Chinese-speaking cybercrime group dubbed UAT-10147 that's targeting Windows and Linux web servers globally across the education, media, technology, and gaming sectors. The vast majority of the targets are located in Brazil, Bolivia, China,...

CVE-2026-74683

In the Linux kernel, the following vulnerability has been resolved: Input: evdev - sanitize event type index when fetching event masks The user-supplied event type index passed to EVIOCGMASK / EVIOCSMASK ioctls is used to index the static counts array in evdevgetmaskcnt and client evmasks array i...

UAT-10147 deploys SPECTRE: A cross-platform implant with Linux rootkit and BYOVD capabilities

UAT-10147 is a highly capable Chinese-speaking intrusion actor operating a multi-platform post-exploitation ecosystem targeting IIS and Linux servers, combining search engine optimization SEO fraud monetization with advanced persistence and defense evasion techniques. The newly identified SPECTRE...

Cloudflare Workers Spectre Attack Leaks JWT From Co-Located Worker at 12 Bits/Second

Cybersecurity researchers have disclosed details of a remote Spectre attack against Cloudflare Workers that leaked a JSON Web Token JWT from a co-located Worker in the production environment at up to 12 bits per second, 360 times the rate of an earlier attack demonstrated in 2021. The end-to-end...

Linux Distros Unpatched Vulnerability : CVE-2026-72428

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: Fix stack slot index in nospec checks checkstackwritefixedoff computes the byte slot for a fixed-offset stack write as -off - 1, and records each written...

CVE-2026-72428

A flaw was found in the Berkeley Packet Filter BPF component of the Linux kernel. An incorrect calculation of the stack slot index during Spectre v4 sanitization checks could result in certain memory bytes not being properly sanitized. This vulnerability might allow an attacker to potentially...
