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. The Linux kernel CVE team has assigned CVE-2026-43307 to this issue.

Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-43307 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/iio/accel/adxl380.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/a40f316085985f916ba1599fc303fdbc6a078e86 https://git.kernel.org/stable/c/a8e88edfd69df7b63c882aa53e61e7c078806ad7 https://git.kernel.org/stable/c/f42ddb2945ae4ce2b6f1c2e7aae9f14455a734d3 https://git.kernel.org/stable/c/c1b14015224cfcccd5356333763f2f4f401bd810
