CVE-2024-36884

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.9.0-0.rc7.58.eln136.aarch64

Description The vulnerability is related to the iommu/arm-smmu component in the Linux kernel. It was caused by a function pointer indirection issue in the nvidia smmu context fault() function, which is also installed as an IRQ function. The 'void *' was changed to a struct arm smmu domain, but since the iommu domain is embedded at a non-zero offset, this causes nvidia smmu context fault() to miscompute the offset. The issue results in a kernel NULL pointer dereference at a virtual address.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
