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 cyclic locking dependency between reqlock and the work queue in nciclosedevice, potentially...

PT-2026-34414

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A circular locking dependency exists in the NFC NCI component. The nci close device function flushes rx wq and tx wq while holding the req lock mutex. This creates a conflict because nci...

CVE-2026-23339

A flaw was found in the Linux kernel's Near Field Communication NFC subsystem. When the ncitransceive function encounters certain error conditions, it fails to properly free allocated kernel memory. This memory leak can accumulate over time, potentially leading to resource exhaustion and affectin...
