Oracle Linux: CVE-2024-42277: ELSA-2024-12815: Unbreakable Enterprise kernel security update (IMPORTANT) (Multiple Advisories)
Description
In the Linux kernel, the following vulnerability has been resolved: iommu: sprd: Avoid NULL deref in sprd_iommu_hw_en In sprd_iommu_cleanup() before calling function sprd_iommu_hw_en() dom->sdev is equal to NULL, which leads to null dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE. A flaw was identified and fixed in the Linux kernel's Spreadtrum (sprd) IOMMU driver. This issue occurred in the `sprd_iommu_cleanup()` function, where a null pointer dereference happened when calling `sprd_iommu_hw_en()`, as `dom->sdev` was `NULL`. This problem could lead to kernel crashes or instability. The bug was discovered by the Linux Verification Center using SVACE.
