CVSS: 6.8EPSS: 0%CPEs: 2EXPL: 0CVE-2024-35843 – iommu/vt-d: Use device rbtree in iopf reporting path
https://notcve.org/view.php?id=CVE-2024-35843
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Use device rbtree in iopf reporting path The existing I/O page fault handler currently locates the PCI device by calling pci_get_domain_bus_and_slot(). This function searches the list of all PCI devices until the desired device is found. To improve lookup efficiency, replace it with device_rbtree_find() to search the device within the probed device rbtree. The I/O page fault is initiated by the device, which does not have any synchronization mechanism with the software to ensure that the device stays in the probed device tree. Theoretically, a device could be released by the IOMMU subsystem after device_rbtree_find() and before iopf_get_dev_fault_param(), which would cause a use-after-free problem. Add a mutex to synchronize the I/O page fault reporting path and the IOMMU release device path. This lock doesn't introduce any performance overhead, as the conflict between I/O page fault reporting and device releasing is very rare. • https://git.kernel.org/stable/c/3d39238991e745c5df85785604f037f35d9d1b15 https://git.kernel.org/stable/c/def054b01a867822254e1dda13d587f5c7a99e2a • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2024-35831
In the Linux kernel, the following vulnerability has been resolved: io_uring: Fix release of pinned pages when __io_uaddr_map fails Looking at the error path of __io_uaddr_map, if we fail after pinning the pages for any reasons, ret will be set to -EINVAL and the error handler won't properly release the pinned pages. I didn't manage to trigger it without forcing a failure, but it can happen in real life when memory is heavily fragmented. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: io_uring: corregida la liberación de páginas fijadas cuando falla __io_uaddr_map. Mirando la ruta de error de __io_uaddr_map, si fallamos después de fijar las páginas por cualquier motivo, ret se establecerá en -EINVAL y el El controlador de errores no libera correctamente las páginas fijadas. No logré activarlo sin forzar un fallo, pero puede suceder en la vida real cuando la memoria está muy fragmentada. • https://git.kernel.org/stable/c/223ef474316466e9f61f6e0064f3a6fe4923a2c5 https://git.kernel.org/stable/c/3f3164ce6396138747984ee9e61158e248246300 https://git.kernel.org/stable/c/0b6f39c175ba5f0ef72bdb3b9d2a06ad78621d62 https://git.kernel.org/stable/c/712e2c8415f55a4a4ddaa98a430b87f624109f69 https://git.kernel.org/stable/c/4d376d7ad62b6a8e8dfff56b559d9d275e5b9b3a https://git.kernel.org/stable/c/67d1189d1095d471ed7fa426c7e384a7140a5dd7 •
