In the Linux kernel, the following vulnerability has been resolved: RDMA/erdma: complete object teardown when the destroy command fails erdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and erdma_destroy_ah() returned early when erdma_post_cmd_wait() failed, leaking the queue buffers,…

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix integer overflow of user QP buffer size set_user_buf_size() computes the QP buffer size by left-shifting the user-supplied rq.wqe_cnt and rq.wqe_shift values as signed integers. A sufficiently large rq.wqe_cnt…

In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Require exactly one Stream ID for a vSID tegra241_vintf_init_vsid() maps a guest vSID to a single physical Stream ID taken from master->streams[0], and only warns when the device does not have exactly one…

In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Don't fall back to a freed smmu after devm_krealloc() __tegra241_cmdqv_probe() uses devm_krealloc() to grow @smmu into the larger tegra241_cmdqv, which frees the original @smmu once it relocates. A…

In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF (de)init A user VINTF is torn down by tegra241_cmdqv_deinit_vintf(), which runs from the destroy callback and from the init-failure unwind in the alloc handler. It…

In the Linux kernel, the following vulnerability has been resolved: nilfs2: prevent out-of-bounds read in super root block parsing super-root inode metadata size is trusted before nilfs_read_inode_common(). Reject super-root inode sizes whose computed on-disk footprint exceeds the filesystem…

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix UAF in ODP init error-handling path rxe_odp_mr_init_user() stores &umem_odp->umem in mr->umem before calling rxe_odp_init_pages(). If rxe_odp_init_pages() fails, rxe_odp_mr_init_user() releases umem_odp and returns…

In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: pci: fix error path in rtl_pci_probe() In the last error path in rtl_pci_probe(), the cleanup functions are skipped due to a wrong goto label. Moreover, the successful call to rtl_init_rfkill(),…

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix overreads in ath11k_wmi_process_csa_switch_count_event() There is no policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT, so the parse infrastructure does not enforce a minimum length for the…

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix overreads in ath12k_wmi_process_csa_switch_count_event() There is no policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT, so the parse infrastructure does not enforce a minimum length for the…

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix stride mismatch in mac_phy_caps_parse() Currently, in ath11k_wmi_tlv_mac_phy_caps_parse(), kcalloc() sizes the mac_phy_caps buffer as tot_phy_id * len, where len is clamped to min(firmware_len, sizeof(struct…

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix stride mismatch in mac_phy_caps_parse() Currently, in ath12k_wmi_mac_phy_caps_parse(), kzalloc() sizes the mac_phy_caps buffer as tot_phy_id * len, where len is clamped to min(firmware_len, sizeof(struct…

In the Linux kernel, the following vulnerability has been resolved: md: remove REQ_NOWAIT support from raid1/10/456 REQ_NOWAIT support in md personalities that can block internally is fundamentally incomplete. While reads can avoid some blocking paths, write requests can still encounter cases…

In the Linux kernel, the following vulnerability has been resolved: bus: mhi: host: Fix controller cleanup on EDL sysfs failure mhi_register_controller() adds the controller device before creating the optional trigger_edl sysfs file. If sysfs_create_file() fails, the error path only drops the…

In the Linux kernel, the following vulnerability has been resolved: swiotlb: Preserve allocation virtual address for dynamic pools swiotlb_alloc_tlb() can allocate from the DMA atomic pool when a decrypted pool is needed from atomic context. With CONFIG_DMA_DIRECT_REMAP, the atomic pool is…

In the Linux kernel, the following vulnerability has been resolved: iommu/dma: Check atomic pool allocation result directly The non-blocking, non-coherent allocation path uses dma_alloc_from_pool(), which returns the allocated page and fills cpu_addr only on success. Do not rely on cpu_addr to…

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix potential UAF when reading bpf link info In bpf_link_show_fdinfo and bpf_link_get_info_by_fd, link->prog is accessed without holding any locks. If the prog is concurrently replaced via bpf_link_update, the old prog can…

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: Add PCIe AER handler support to prevent system crash When an AER error occurs and the bus is hung, the register reads return 0xFFFFFFFF, causing the DMA queue state to be corrupted and resulting in an invalid…

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt792x: fix use-after-free in mt76_rx_poll_complete A use-after-free issue occurs in mt76_rx_poll_complete due to a race condition. The STA has already been removed, but the rx_status still had a pointer to the wcid…

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix handling channel context with different bands in mt76_switch_vif_chanctx() When performing channel switches on different radios within a short timeframe, channel contexts with different bands can be carried…

In the Linux kernel, the following vulnerability has been resolved: misc: sgi-gru: remove interrupt-context page-table walks The GRU TLB miss handler walks a process's page tables without holding page-table locks or a reference to the mapped page. It also uses a kernel page-table accessor on…

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix RXDMAD_C buffer recycling race The RXDMAD_C buffers come from the RRO data queues' page pools, which are bound to a different NAPI, so the direct page-pool recycle used here could race the owning NAPI; take the…
