Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of holding the device lock during nandlock and nandunlock operations, potentially leadin...

CVE-2026-23295

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix dead lock for suspend and resume When an application issues a query IOCTL while auto suspend is running, a deadlock can occur. The query path holds devlock and then calls pmruntimeresumeandget, which waits for...

SUSE CVE-2026-23999

Fleet is open source device management software. In versions prior to 4.80.1, Fleet generated device lock and wipe PINs using a predictable algorithm based solely on the current Unix timestamp. Because no secret key or additional entropy was used, the resulting PIN could potentially be derived if...

CVE-2026-23999

CVE-2026-23999 affects Fleet open source device management before version 4.80.1. The vulnerability stems from a predictable 6‑digit PIN (device lock/wipe) derived from the current Unix timestamp without secret entropy, allowing an attacker with physical access and knowledge of approximate lock t...
