The device usage count is also unconditionally incremented. Use pm_runtime_resume_and_get() which propagates errors and avoids incrementing the usage count on failure. In preenable, add pm_runtime_put_autosuspend() on set_8khz_samplerate() failure since postdisable does not run when preenable fails. The Linux kernel CVE team has assigned CVE-2026-43357 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/iio/gyro/mpu3050-core.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/935f57dd43492240e1ca220dd065d624efece6be https://git.kernel.org/stable/c/8544c488e50206f00630a8bbba43d2c8bd290345 https://git.kernel.org/stable/c/35f54e7bcb1eccdc6e5bff06580eeef2e0ff3677 https://git.kernel.org/stable/c/2a86a396aa001a9f9ba2d37dda36573a76f17c90 https://git.kernel.org/stable/c/66c0d1d600e7be034959cf49edab104cb5a39258 https://git.kernel.org/stable/c/42685cf96e28262e0b84d74447f3d99f3f6a72e0 https://git.kernel.org/stable/c/7a3dec5b265cf87678b10c98a72a435a8e769bb7 https://git.kernel.org/stable/c/acc3949aab3e8094641a9c7c2768de1958c88378
