CVE-2026-89942

CVE-2026-89942 is a use-after-free in the Linux kernel's IIO buffer subsystem, specifically in the anonymous buffer release path. When an anonymous buffer handle holds the last reference to an IIO device that has been removed (via unbind or hot-unplug), the release function's scoped guard causes ...

CVE-2026-89941

CVE-2026-89941 is a use-after-free vulnerability in the Linux kernel IIO buffer subsystem (iio: buffer). The iio_dma_fence implementation provided a custom release callback that called kfree(), which is not RCU-safe as required by the dma_fence documentation. The fix removes the custom release, a...

CVE-2026-89940 iio: buffer: Tie IIO dma fence lock lifetime to the fence

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Tie IIO dma fence lock lifetime to the fence The iiodmafence implementation currently uses a lock embedded in the iiodmabufpriv. But the iiodmafence can outlive the iiodmabufpriv, which can cause a use-after-free. Ti...

CVE-2026-89940

CVE-2026-89940 is a use-after-free in the Linux kernel's IIO buffer subsystem. The iio_dma_fence implementation used a lock embedded in iio_dmabuf_priv, but the fence can outlive the iio_dmabuf_priv struct, leading to a use-after-free when the fence accesses the freed lock. The fix ties the lock'...
