In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Bounds-check devid in rlookupamdiommu iommudeviceregister walks every device on the PCI bus via busforeachdev and calls amdiommuprobedevice for each. The inlined checkdevice path computes the device's sbdf, calls...

CVE-2026-53283

CVE-2026-53283 covers a bounds-check failure in the Linux kernel AMD IOMMU path. The issue arises in __rlookup_amd_iommu(): rlookup_table[devid] is indexed without an internal bounds check, and iommu_device_register() iterates all PCI devices, calling amd_iommu_probe_device() for each. If a devic...

CVE-2026-53178

A flaw was found in the Linux kernel, specifically within the rtl8723bs Wi-Fi driver's rtwmlme component. This vulnerability is due to a missing bounds check before subtracting fixed offsets from the ielength variable, which can lead to an unsigned integer underflow. This issue could potentially...
