CVE-2022-49482

In the Linux kernel, CVE-2022-49482 concerns the ASoC: mxs-saif driver. The root cause is a refcount leak where of_parse_phandle() returns a node pointer with an incremented refcount that is not released unless a corresponding of_node_put() is invoked when done. The documented fix is to call of_n...

CVE-2022-49462

The CVE-2022-49462 issue affects the Linux kernel DRM MSM A6xx driver (a6xx_gpu_init). Root cause: of_parse_phandle() returns a node pointer with refcount incremented and a missing of_node_put() leads to a refcount leak. The code path in a6xx_gmu_init() passes the node to of_find_device_by_node()...

In the Linux kernel, the following vulnerability has been resolved: mfd: davincivoicecodec: Fix possible null-ptr-deref davincivcprobe It will cause null-ptr-deref when using 'res', if platformgetresource returns NULL, so move using 'res' after devmioremapresource that will check it to avoid...

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-2022-49415

The CVE-2022-49415 description is supported by multiple connected sources indicating a Linux kernel issue: ipmi:ipmb: Fix refcount leak in ipmi_ipmb_probe. The root cause is that of_parse_phandle() returns a node pointer with its refcount incremented, and the proper cleanup requires calling of_no...

CVE-2022-49397

CVE-2022-49397 affects the Linux kernel, in the phy: qcom-qmp driver. The vulnerability is a leak of a struct clk (pipe clock reference) on probe errors, including late probe error/deferral paths. The advisory states the fix releases the held pipe clock reference on such errors, i.e., a proper cl...

CVE-2022-49390
