CVE-2026-90430

CVE-2026-90430 is a race condition in the Linux kernel's Tegra241 IOMMU command queue virtualization (iommu/tegra241-cmdqv) driver. The function tegra241_vintf_init_lvcmdq() stored a freshly allocated vcmdq pointer into the vintf->lvcmdqs[] array before the underlying arm_smmu_cmdq was fully b...

CVE-2026-90429 iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF (de)init

In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF deinit A user VINTF is torn down by tegra241cmdqvdeinitvintf, which runs from the destroy callback and from the init-failure unwind in the alloc handler.

CVE-2026-90428

CVE-2026-90428 affects the Linux kernel driver iommu/tegra241-cmdqv (NVIDIA Tegra 241 CMDQV IOMMU). The root cause is that __tegra241_cmdqv_probe() requests the error IRQ before allocating the cmdqv->vintfs array and setting cmdqv->num_vintfs. If a CMDQV is left enabled with a latched error...
