| CVE-2022-48809 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: fix a memleak when uncloning an skb dst and its metadata When uncloning an skb dst and its associated metadata, a new dst+metadata is allocated and later replaces the old one in the skb. This is helpful to have a non-shared dst+metadata attached to a specific skb. The issue is the uncloned dst+metadata is initialized with a refcount of 1, which is increased to 2 before attaching it to the skb. When tun_dst_unclone returns, the dst+metadata is only referenced from a single place (the skb) while its refcount is 2. Its refcount will never drop to 0 (when the skb is consumed), leading to a memory leak. Fix this by removing the call to dst_hold in tun_dst_unclone, as the dst+metadata refcount is already 1. | ||||
| CVE-2022-48794 | 2025-05-04 | 6.1 Medium | ||
| In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: at86rf230: Stop leaking skb's Upon error the ieee802154_xmit_complete() helper is not called. Only ieee802154_wake_queue() is called manually. In the Tx case we then leak the skb structure. Free the skb structure upon error before returning when appropriate. As the 'is_tx = 0' cannot be moved in the complete handler because of a possible race between the delay in switching to STATE_RX_AACK_ON and a new interrupt, we introduce an intermediate 'was_tx' boolean just for this purpose. There is no Fixes tag applying here, many changes have been made on this area and the issue kind of always existed. | ||||
| CVE-2022-48775 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Fix memory leak in vmbus_add_channel_kobj kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()： If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Fix memory leak by calling kobject_put(). | ||||

| In the Linux kernel, the following vulnerability has been resolved: block: fix memory leak in disk_register_independent_access_ranges kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add() If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Fix this issue by adding kobject_put(). Callback function blk_ia_ranges_sysfs_release() in kobject_put() can handle the pointer "iars" properly. | ||||

Call is made to correct return statement so memory does not leak. ifcvf_init_hw does not take care of this so it is needed to do it here. | ||||

| In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix percpu memory leak at nf_tables_addchain() It seems to me that percpu memory for chain stats started leaking since commit 3bc158f8d0330f0a ("netfilter: nf_tables: map basechain priority to hardware priority") when nft_chain_offload_priority() returned an error. | ||||

| CVE-2023-53018 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_conn: Fix memory leaks When hci_cmd_sync_queue() failed in hci_le_terminate_big() or hci_le_big_terminate(), the memory pointed by variable d is not freed, which will cause memory leak. Add release process to error path. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: fix memory leak in hci_update_adv_data() When hci_cmd_sync_queue() failed in hci_update_adv_data(), inst_ptr is not freed, which will cause memory leak, convert to use ERR_PTR/PTR_ERR to pass the instance to callback so no memory needs to be allocated. | ||||
| CVE-2023-53014 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: tegra: Fix memory leak in terminate_all() Terminate vdesc when terminating an ongoing transfer. This will ensure that the vdesc is present in the desc_terminated list The descriptor will be freed later in desc_free_list(). This fixes the memory leaks which can happen when terminating an ongoing transfer. | ||||
| CVE-2023-53008 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: cifs: fix potential memory leaks in session setup Make sure to free cifs_ses::auth_key.response before allocating it as we might end up leaking memory in reconnect or mounting. | ||||
| CVE-2023-53002 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix a memory leak with reused mmap_offset drm_vma_node_allow() and drm_vma_node_revoke() should be called in balanced pairs. We call drm_vma_node_allow() once per-file everytime a user calls mmap_offset, but only call drm_vma_node_revoke once per-file on each mmap_offset. As the mmap_offset is reused by the client, the per-file vm_count may remain non-zero and the rbtree leaked. Call drm_vma_node_allow_once() instead to prevent that memory leak. | ||||
| CVE-2023-53001 | 1 Linux | 1 Linux Kernel | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/drm_vma_manager: Add drm_vma_node_allow_once() Currently there is no easy way for a drm driver to safely check and allow drm_vma_offset_node for a drm file just once. Allow drm drivers to call non-refcounted version of drm_vma_node_allow() so that a driver doesn't need to keep track of each drm_vma_node_allow() to call subsequent drm_vma_node_revoke() to prevent memory leak. | ||||
