简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- i2cnpcm禁用 devm_request_irq 前的中断启用位 客户报告存在与 i2c 驱动程序相关的软锁定问题。经检查i2c 模块当时正在执行 tx 传输bmc 计算机在 i2c 事务期间重新启动i2c 模块保持此状态而不重置。
由于此类 i2c 模块状态i2c irq 处理程序会不断被触发这是因为 i2c irq 处理程序是在 bmc 计算机执行热重新启动之后在内核启动进程中注册的。连续触发被软锁定监视程序定时器停止。在调用 devm_request_irq 以修复此问题之前禁用 i2c 模块中的中断启用位因为 i2c 相对状态位为只读。
