Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： iio: pressure: bmp280：修复采样频率查找中的越界访问问题 采样频率表将每个频率以整数部分和微单位的小数部分形式存储。 初始化为扁平化后整数元素的数量，因为 将该表作为一维数组返回。 然而， 却将该表作为二维数组进行索引，并将 当作行数使用。在遍历该表之前，需将扁平化后的元素数量还原为行数。

Vulnerability Title
iio: pressure: bmp280: fix out-of-bounds access in sampling frequency lookup
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: iio: pressure: bmp280: fix out-of-bounds access in sampling frequency lookup The sampling frequency tables store each frequency as an integer part and a fractional part in micro units. num_sampling_freq_avail is initialized to the number of flattened integer elements because read_avail() returns the table as a flat array. bmp280_write_sampling_frequency(), however, indexes the same table as a two-dimensional array and uses num_sampling_freq_avail as the number of rows. Convert the flattened element count back to the number of rows before iterating over the table.
