| CVE-2024-38554 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ax25: Fix reference count leak issue of net_device There is a reference count leak issue of the object "net_device" in ax25_dev_device_down(). When the ax25 device is shutting down, the ax25_dev_device_down() drops the reference count of net_device one or zero times depending on if we goto unlock_put or not, which will cause memory leak. In order to solve the above issue, decrease the reference count of net_device after dev->ax25_ptr is set to null. | ||||
| CVE-2024-36959 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map() If we fail to allocate propname buffer, we need to drop the reference count we just took. Because the pinctrl_dt_free_maps() includes the droping operation, here we call it directly. | ||||

The root case is, during f2fs_put_super(), if there is any IO error in f2fs_wait_on_all_pages(), we missed to truncate meta_inode's page cache later, result in panic, fix this case. | ||||
| CVE-2024-53075 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: riscv: Prevent a bad reference count on CPU nodes When populating cache leaves we previously fetched the CPU device node at the very beginning. But when ACPI is enabled we go through a specific branch which returns early and does not call 'of_node_put' for the node that was acquired. Since we are not using a CPU device node for the ACPI code anyways, we can simply move the initialization of it just passed the ACPI block, and we are guaranteed to have an 'of_node_put' call for the acquired node. This prevents a bad reference count of the CPU device node. Moreover, the previous function did not check for errors when acquiring the device node, so a return -ENOENT has been added for that case. | ||||
| CVE-2024-50021 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ice: Fix improper handling of refcount in ice_dpll_init_rclk_pins() This patch addresses a reference count handling issue in the ice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(), which increments the reference count of the relevant resources. However, if the condition WARN_ON((!vsi || !vsi->netdev)) is met, the function currently returns an error without properly releasing the resources acquired by ice_dpll_get_pins(), leading to a reference count leak. To resolve this, the check has been moved to the top of the function. This ensures that the function verifies the state before any resources are acquired, avoiding the need for additional resource management in the error path. This bug was identified by an experimental static analysis tool developed by our team. The tool specializes in analyzing reference count operations and detecting potential issues where resources are not properly managed. In this case, the tool flagged the missing release operation as a potential problem, which led to the development of this patch. | ||||
| CVE-2024-50020 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ice: Fix improper handling of refcount in ice_sriov_set_msix_vec_count() This patch addresses an issue with improper reference count handling in the ice_sriov_set_msix_vec_count() function. First, the function calls ice_get_vf_by_id(), which increments the reference count of the vf pointer. If the subsequent call to ice_get_vf_vsi() fails, the function currently returns an error without decrementing the reference count of the vf pointer, leading to a reference count leak. The correct behavior, as implemented in this patch, is to decrement the reference count using ice_put_vf(vf) before returning an error when vsi is NULL. Second, the function calls ice_sriov_get_irqs(), which sets vf->first_vector_idx. If this call returns a negative value, indicating an error, the function returns an error without decrementing the reference count of the vf pointer, resulting in another reference count leak. The patch addresses this by adding a call to ice_put_vf(vf) before returning an error when vf->first_vector_idx < 0. This bug was identified by an experimental static analysis tool developed by our team. The tool specializes in analyzing reference count operations and identifying potential mismanagement of reference counts. In this case, the tool flagged the missing decrement operation as a potential issue, leading to this patch. | ||||
| CVE-2024-49964 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix memfd_pin_folios free_huge_pages leak memfd_pin_folios followed by unpin_folios fails to restore free_huge_pages if the pages were not already faulted in, because the folio refcount for pages created by memfd_alloc_folio never goes to 0. memfd_pin_folios needs another folio_put to undo the folio_try_get below: memfd_alloc_folio() alloc_hugetlb_folio_nodemask() dequeue_hugetlb_folio_nodemask() dequeue_hugetlb_folio_node_exact() folio_ref_unfreeze(folio, 1); ; adds 1 refcount folio_try_get() ; adds 1 refcount hugetlb_add_to_page_cache() ; adds 512 refcount (on x86) With the fix, after memfd_pin_folios + unpin_folios, the refcount for the (unfaulted) page is 512, which is correct, as the refcount for a faulted unpinned page is 513. | ||||

| CVE-2024-42257 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ext4: use memtostr_pad() for s_volume_name As with the other strings in struct ext4_super_block, s_volume_name is not NUL terminated. The other strings were marked in commit 072ebb3bffe6 ("ext4: add nonstring annotations to ext4.h"). Using strscpy() isn't the right replacement for strncpy(); it should use memtostr_pad() instead. | ||||
