In the Linux kernel, the following vulnerability has been
resolved: nfsd: fix use-after-free due to delegation race A delegation
break could arrive as soon as we've called vfs_setlease. A delegation break
runs a callback which immediately (in nfsd4_cb_recall_prepare) adds the
delegation to del_recall_lru. If we then exit nfs4_set_delegation without
hashing the delegation, it will be freed as soon as the callback is done

later as use-after-free or list corruption warnings, usually in the

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information

## UAT-10147 Uses AI to Scale Server Attacks, Deploys SPECTRE With EDR Bypass and Linux Rootkit
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, Canada, and Vietnam. Details of the threat activity came to light following the discovery of an open directory hosted at "139.180.197[.]150," which was observed communicating with one of the compromised machines.

CVE-2022-0995 UAT-10147: Chinese-speaking adversary integrates agentic AI into post-compromise operations
## UAT-10147: Chinese-speaking adversary integrates agentic AI into post-compromise operations
Cisco Talos identified UAT-10147 targeting Windows and Linux web servers globally, impacting organizations in government, education, media, technology, and gaming sectors. The actor leveraged publicly disclosed vulnerabilities to gain initial access at scale.
UAT-10147 integrated AI-driven tooling into exploitation, reconnaissance, payload generation, validation, and persistence workflows. Talos observed AI-generated operational playbooks, exploit automation scripts, and troubleshooting logic supporting real-world intrusions.
The actor employed a mixture of open-source offensive frameworks, including Metasploit, ysoserial, PentestGPT, DeepAudit, and multiple privilege escalation exploits to au
