CVE-2022-48896 – ixgbe: fix pci device refcount leak
https://notcve.org/view.php?id=CVE-2022-48896
21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: ixgbe: fix pci device refcount leak As the comment of pci_get_domain_bus_and_slot() says, it returns a PCI device with refcount incremented, when finish using it, the caller must decrement the reference count by calling pci_dev_put(). In ixgbe_get_first_secondary_devfn() and ixgbe_x550em_a_has_mii(), pci_dev_put() is called to avoid leak.

CVE-2022-48893 – drm/i915/gt: Cleanup partial engine discovery failures
https://notcve.org/view.php?id=CVE-2022-48893
21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Cleanup partial engine discovery failures If we abort driver initialisation in the middle of gt/engine discovery, some engines will be fully setup and some not. Those incompletely setup engines only have 'engine->release == NULL' and so will leak any of the common objects allocated. v2: - Drop the destroy_pinned_context() helper for now. It's not really worth it with just a single callsite at the moment. (Janusz) In the Linux k... • https://git.kernel.org/stable/c/5c855bcc730656c4b7d30aaddcd0eafc7003e112 •
CVE-2022-48891 – regulator: da9211: Use irq handler when ready
https://notcve.org/view.php?id=CVE-2022-48891
21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: regulator: da9211: Use irq handler when ready If the system does not come from reset (like when it is kexec()), the regulator might have an IRQ waiting for us. If we enable the IRQ handler before its structures are ready, we crash.

CVE-2022-48887 – drm/vmwgfx: Remove rcu locks from user resources

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Remove rcu locks from user resources User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was easy to make the driver crash by submitting command buffers from two different threads. Because the lookups never show up in performance profiles replace them with a regular spin lock which fixes the races in accesses to those shared resources.
