Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-06-19 15:33In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: ns: Free the node during ctrl_cmd_bye()
A node sends the BYE packet when it is about to go down. So the nameserver should advertise the removal of the node to all remote and local observers and free the node finally. But currently, the nameserver doesn't free the node memory even after processing the BYE packet. This causes the node memory to leak.
Hence, remove the node from Xarray list and free the node memory during both success and failure case of ctrl_cmd_bye().

Vulnerability from github – Published: 2026-07-13 18:30 – Updated: 2026-08-03 12:32In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: Fix memory leak in hci_le_big_terminate()
hci_le_big_terminate() allocates iso_list_data via kzalloc_obj but returns 0 without freeing it when neither pa_sync_term nor big_sync_term flags are set after evaluating the PA and BIG sync connection state.
This early-return path was introduced when hci_le_big_terminate() was refactored to take struct hci_conn instead of raw u8 parameters, adding PA/BIG flag evaluation logic. The existing kfree() on hci_cmd_sync_queue failure does not cover this path.

mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets some error, mhi_ctrl should be freed with mhi_free_controller(). But when ath11k_mhi_read_addr_from_dt() fails, the function returns without calling mhi_free_controller(), which will lead to a memory leak.
We can fix it by calling mhi_free_controller() when ath11k_mhi_read_addr_from_dt() fails.

GHSA-PG5J-WJ7F-H3MX
Vulnerability from github – Published: 2025-03-18 21:32 – Updated: 2025-11-03 21:32In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: fix memory leak during D3hot to D0 transition
If 'vfio_pci_core_device::needs_pm_restore' is set (PCI device does not have No_Soft_Reset bit set in its PMCSR config register), then the current PCI state will be saved locally in 'vfio_pci_core_device::pm_save' during D0->D3hot transition and same will be restored back during D3hot->D0 transition. For saving the PCI state locally, pci_store_saved_state() is being used and the pci_load_and_free_saved_state() will free the allocated memory.
But for reset related IOCTLs, vfio driver calls PCI reset-related API's which will internally change the PCI power state back to D0. So, when the guest resumes, then it will get the current state as D0 and it will skip the call to vfio_pci_set_power_state() for changing the power state to D0 explicitly. In this case, the memory pointed by 'pm_save' will never be freed. In a malicious sequence, the state changing to D3hot followed by VFIO_DEVICE_RESET/VFIO_DEVICE_PCI_HOT_RESET can be run in a loop and it can cause an OOM situation.
This patch frees the earlier allocated memory first before overwriting 'pm_save' to prevent the mentioned memory leak.

"details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvfio/pci: fix memory leak during D3hot to D0 transition\n\nIf \u0027vfio_pci_core_device::needs_pm_restore\u0027 is set (PCI device does\nnot have No_Soft_Reset bit set in its PMCSR config register), then\nthe current PCI state will be saved locally in\n\u0027vfio_pci_core_device::pm_save\u0027 during D0-\u003eD3hot transition and same\nwill be restored back during D3hot-\u003eD0 transition.\nFor saving the PCI state locally, pci_store_saved_state() is being\nused and the pci_load_and_free_saved_state() will free the allocated\nmemory.\n\nBut for reset related IOCTLs, vfio driver calls PCI reset-related\nAPI\u0027s which will internally change the PCI power state back to D0. So,\nwhen the guest resumes, then it will get the current state as D0 and it\nwill skip the call to vfio_pci_set_power_state() for changing the\npower state to D0 explicitly. In this case, the memory pointed by\n\u0027pm_save\u0027 will never be freed. In a malicious sequence, the state changing\nto D3hot followed by VFIO_DEVICE_RESET/VFIO_DEVICE_PCI_HOT_RESET can be\nrun in a loop and it can cause an OOM situation.\n\nThis patch frees the earlier allocated memory first before overwriting\n\u0027pm_save\u0027 to prevent the mentioned memory leak.",

Mitigation MIT-41
Strategy: Libraries or Frameworks
- Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
- For example, glibc in Linux provides protection against free of invalid pointers.
- When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
- To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
