CVE-2026-43009

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The verifier, responsible for ensuring the safety of BPF programs, incorrectly tracks the precision of atomic fetch operations. This error can lead to the verifier pruning execution paths that should not be considered...

CVE-2026-43009

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix incorrect pruning due to atomic fetch precision tracking When backtrackinsn encounters a BPFSTX instruction with BPFATOMIC and BPFFETCH, the src register or r0 for BPFCMPXCHG also acts as a destination, thus receiving th...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the bpf backtrace not handling atomic fetch operations correctly, which could lead to path pruning errors...

LingoLoop Attack: Trapping MLLMs via Linguistic Context and State Entrapment into Endless Loops

Multimodal Large Language Models MLLMs have shown great promise but require substantial computational resources during inference. Attackers can exploit this by inducing excessive output, leading to resource exhaustion and service degradation. Prior energy-latency attacks aim to increase generatio...
