CVE-2026-45996

The CVE-2026-45996 issue affects the Linux kernel SPI imx driver, where a use-after-free can occur on unbind because the SPI subsystem frees controller and subsystem data during deregistration unless the allocation is device-managed. The fix adds a reference before deregistering the controller so...

CVE-2026-45989

In the Linux kernel CVE-2026-45989, a use-after-free occurs in testdrv_probe() where a released device_node (via of_node_put) may later be passed to of_platform_default_populate(), risking use-after-free of the freed pointer. The root cause is that pdev->dev.of_node is owned by the device mode...

CVE-2026-45984 gfs2: Fix use-after-free in iomap inline data write path

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix use-after-free in iomap inline data write path The inline data buffer head dibh is being released prematurely in gfs2iomapbegin via releasemetapath while iomap-inlinedata still points to dibh-bdata. This causes a...

CVE-2026-45981

In CVE-2026-45981, the Linux kernel s390/cio path css_alloc_subchannel() calls device_initialize() before configuring DMA masks. If dma_set_coherent_mask() or dma_set_mask() fails, the error path frees the subchannel directly, bypassing the device model reference counting. After device_initialize...
