CVE-2026-98660: iio: pressure: bmp280: fix out-of-bounds access in sampling frequency lookup

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 05ef1af381a0f4556c7e3c0dc6bc2428d16c707e, 4fd5a61e61d6899cbd45728a5fceba49a53c222d, 56c423b233b214182c58c99861899327b45b0d6c; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.

Low priority for now. Upgrade to Linux Linux 05ef1af381a0f4556c7e3c0dc6bc2428d16c707e, 4fd5a61e61d6899cbd45728a5fceba49a53c222d, 56c423b233b214182c58c99861899327b45b0d6c; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
