CVE-2026-43307
7.8 · HIGHOverview
CVE-2026-43307 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 8, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
iio: accel: adxl380: Avoid reading more entries than present in FIFO
The interrupt handler reads FIFO entries in batches of N samples, where N
is the number of scan elements that have been enabled. However, the sensor
fills the FIFO one sample at a time, even when more than one channel is
enabled. Therefore,the number of entries reported by the FIFO status
registers may not be a multiple of N; if this number is not a multiple, the
number of entries read from the FIFO may exceed the number of entries
actually present.
To fix the above issue, round down the number of FIFO entries read from the
status registers so that it is always a multiple of N.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
