This patch fixes this by using the open_how struct that we store inside the audit_context with audit_openat2_how(). unbiased of this patch, Richard male Briggs posted an identical patch on the audit mailing list around 40 minutes following this patch was posted.
Failure to effectively synchronize person's permissions in UAA in Cloud Foundry Basis v40.17.0 , probably resulting in people retaining entry legal rights they should not have. This could permit them to conduct functions further than their supposed permissions.
previous to commit 45bf39f8df7f ("USB: Main: Don't keep unit lock although looking through the "descriptors" sysfs file") this race could not come about, because the routines were being mutually exceptional because of the unit locking. eradicating that locking from read_descriptors() uncovered it to your race. The easiest method to correct the bug is to keep hub_port_init() from altering udev->descriptor the moment udev has long been initialized and registered. motorists anticipate the descriptors stored from the kernel for being immutable; we must not undermine this expectation. in actual fact, this transformation must have been built long ago. So now hub_port_init() will choose an extra argument, specifying a buffer through which to store the device descriptor it reads. (If udev has not nonetheless been initialized, the buffer pointer is going to be NULL and then hub_port_init() will store the gadget descriptor in udev as right before.) This removes the info race responsible for the out-of-bounds read through. The changes to hub_port_init() appear a lot more substantial than they really are, thanks to indentation improvements resulting from an attempt to stay away from crafting to other elements of the usb_device framework soon after it has been initialized. very similar adjustments needs to be manufactured for the code that reads the BOS descriptor, but that can be handled in the separate patch afterwards. This patch is sufficient to repair the bug identified by syzbot.
from the Linux kernel, the subsequent vulnerability has actually been settled: drm/vc4: hdmi: Unregister codec device on unbind On bind we will sign-up the HDMI codec product but we don't unregister it on unbind, 9mm sme bringing about a device leakage. Unregister our gadget at unbind.

during the Linux kernel, the following vulnerability has been settled: mm: don't attempt to NUMA-migrate COW pages that have other uses Oded Gabbay experiences that enabling NUMA balancing triggers corruption with his Gaudi accelerator examination load: "All the main points are from the bug, but The underside line is the fact that by some means, this patch causes corruption when the numa balancing feature is enabled AND we don't use process affinity AND we use GUP to pin webpages so our accelerator can DMA to/from technique memory. possibly disabling numa balancing, using process affinity to bind to specific numa-node or reverting this patch triggers the bug to disappear" and Oded bisected The problem to commit 09854ba94c6a ("mm: do_wp_page() simplification"). Now, the NUMA balancing should not really be shifting the writability of the page, and as such should not issue for COW. but it really appears it does. Suspicious. nonetheless, irrespective of that, the ailment for enabling NUMA faults in change_pte_range() is nonsensical.
as an alternative to leaving the kernel inside a partly corrupted point out, Will not try and explicitly clean up and go away this for the process exit path that'll release any even now legitimate fds, such as the a single designed by the prior get in touch with to anon_inode_getfd(). only return -EFAULT to indicate the error.
