CVE-2023-52898 – xhci: Fix null pointer dereference when host dies
https://notcve.org/view.php?id=CVE-2023-52898
21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: xhci: Fix null pointer dereference when host dies Make sure xhci_free_dev() and xhci_kill_endpoint_urbs() do not race and cause null pointer dereference when host suddenly dies. Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id] virt device at the same time that xhci_kill_endpoint_urbs() tries to loop through all the device's endpoints, checking if there are any cancelled urbs left to give back. hold the xhci spinlock whi... • https://git.kernel.org/stable/c/6fac4b5cecb3928a0a81069aaa815a2edc8dd5a1 •

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race between quota rescan and disable leading to NULL pointer deref If we have one task trying to start the quota rescan worker while another one is trying to disable quotas, we can end up hitting a race that results in the quota rescan worker doing a NULL pointer dereference. The steps for this are the following: 1) Quotas are enabled; 2) Task A calls the quota rescan ioctl and enters btrfs_qgroup_rescan(). It calls qgroup_resca... • https://git.kernel.org/stable/c/26b3901d20bf9da2c6a00cb1fb48932166f80a45 •

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Fix GEM handle creation UAF Userspace can guess the handle value and try to race GEM object creation with handle close, resulting in a use-after-free if we dereference the object after dropping the handle's reference. For that reason, dropping the handle's reference must be done *after* we are done dereferencing the object.
