https://notcve.org/view.php?id=CVE-2022-49141
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: net: dsa: felix: fix possible NULL pointer dereference As the possible failure of the allocation, kzalloc() may return NULL pointer. Therefore, it should be better to check the 'sgi' in order to prevent the dereference of NULL pointer. • https://git.kernel.org/stable/c/23ae3a7877718931474684ef4fbbaf1d1511ee84 •

CVE-2022-49140 – Revert "nbd: fix possible overflow on 'first_minor' in nbd_dev_add()"

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: Revert "nbd: fix possible overflow on 'first_minor' in nbd_dev_add()" This reverts commit 6d35d04a9e18990040e87d2bbf72689252669d54. Both Gabriel and Borislav report that this commit casues a regression with nbd: sysfs: cannot create duplicate filename '/dev/block/43:0' Revert it before 5.18-rc1 and we'll investigage this separately in due time. • https://git.kernel.org/stable/c/3b14aa053181709d42319d4145855025c23ddd12 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix null ptr deref on hci_sync_conn_complete_evt This event is just specified for SCO and eSCO link types. On the reception of a HCI_Synchronous_Connection_Complete for a BDADDR of an existing LE connection, LE link type and a status that triggers the second case of the packet processing a NULL pointer dereference happens, as conn->link is NULL. • https://git.kernel.org/stable/c/1c1291a84e94f6501644634c97544bb8291e9a1a •

CVE-2022-49138 – Bluetooth: hci_event: Ignore multiple conn complete events
https://notcve.org/view.php?id=CVE-2022-49138
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: Ignore multiple conn complete events When one of the three connection complete events is received multiple times for the same handle, the device is registered multiple times which leads to memory corruptions. Therefore, consequent events for a single connection are ignored. The conn->state can hold different values, therefore HCI_CONN_HANDLE_UNSET is introduced to identify new connections. To make sure the events do no... • https://git.kernel.org/stable/c/aa1ca580e3ffe62a2c5ea1c095b609b2943c5269 •

CVE-2022-49137 – drm/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj
https://notcve.org/view.php?id=CVE-2022-49137
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: drm/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj This issue takes place in an error path in amdgpu_cs_fence_to_handle_ioctl(). When `info->in.what` falls into default case, the function simply returns -EINVAL, forgetting to decrement the reference count of a dma_fence obj, which is bumped earlier by amdgpu_cs_get_fence(). This may result in reference count leaks. Fix it by decreasing the refcount of specific object before retu... • https://git.kernel.org/stable/c/72d77ddb2224ebc00648f4f78f8a9a259dccbdf7 •

CVE-2022-49136 – Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set hci_cmd_sync_queue shall return an error if HCI_UNREGISTER flag has been set as that means hci_unregister_dev has been called so it will likely cause a uaf after the timeout as the hdev will be freed. • https://git.kernel.org/stable/c/1c69ef84a808676cceb69210addf5df45b741323 •

CVE-2022-49134 – mlxsw: spectrum: Guard against invalid local ports
https://notcve.org/view.php?id=CVE-2022-49134
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum: Guard against invalid local ports When processing events generated by the device's firmware, the driver protects itself from events reported for non-existent local ports, but not for the CPU port (local port 0), which exists, but does not have all the fields as any local port. This can result in a NULL pointer dereference when trying access 'struct mlxsw_sp_port' fields which are not initialized for CPU port.
