CVE-2022-49457

CVE-2022-49457 is a Linux kernel issue in ARM versatile: missing of_node_put in dcscb_init. The of_find_compatible_node call increments the device_node refcount, but the code path did not release it, causing a refcount leak. Connected advisories from Astra/TencentUnity/Linux OSS bulletins confirm...

CVE-2022-49451

CVE-2022-49451 affects the Linux kernel firmware: arm_scmi, base protocol enumeration. The vulnerability stems from improper validation when enumerating SCMI protocols with BASE_DISCOVER_LIST_PROTOCOLS: the check used a sum of unsigned integers that could overflow, allowing bypass of the check if...

CVE-2022-49426 iommu/arm-smmu-v3-sva: Fix mm use-after-free

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3-sva: Fix mm use-after-free We currently call arm64mmcontextput without holding a reference to the mm, which can result in use-after-free. Call mmgrab/mmdrop to ensure the mm only gets freed after we unpinned the...

CVE-2022-49426

CVE-2022-49426 : Linux kernel iommu/arm-smmu-v3-sva had a use-after-free when freeing the MM context because arm64_mm_context_put() ran without a held reference. The root cause is not holding a reference to the MM during unpinning, allowing it to be freed prematurely. The fix is to call mmgrab()/...
