一、漏洞信息
漏洞编号：CVE-2024-57911
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.1.8,6.4.0,6.6.0
CVSS V3.0分值：
BaseScore：7.1 High
Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:iio: dummy: iio_simply_dummy_buffer: fix information leak in triggered bufferThe data array is allocated via kmalloc() and it is used to push datato user space from a triggered buffer, but it does not set values forinactive channels, as it only uses iio_for_each_active_channel()to assign new values.Use kzalloc for the memory allocation to avoid pushing uninitializedinformation to userspace.

状态	分析项目	内容
已分析	1.影响性分析说明	In the Linux kernel, the following vulnerability has been resolved:iio: dummy: iio_simply_dummy_buffer: fix information leak in triggered bufferThe 'data' array is allocated via kmalloc() and it is used to push datato user space from a triggered buffer, but it does not set values forinactive channels, as it only uses iio_for_each_active_channel()to assign new values.Use kzalloc for the memory allocation to avoid pushing uninitializedinformation to userspace.
