A flaw was found in the iommu/msm component of the Linux kernel. This vulnerability occurs when msm_iommu_probe() fails to properly unwind its probe state during registration, leaving a dangling list entry. A local attacker could potentially exploit this to cause a dereference of the dangling list entry, leading to system instability or a denial of service.
