In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: validate TX_CMD response layout TX_CMD parsing uses frame_count to walk status entries and then read the trailing SCD SSN. Make the minimum-length check follow that exact runtime layout calculation before parsing the payload. For new TX API, reject TX_CMD responses with frame_count != 1 and warn/return in th…

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: pcie: null RX pointers after free When iwl_pcie_tx_init() fails after RX init, nic init unwinds via iwl_pcie_rx_free(). The freed RX members stayed non-NULL on the live transport object, so later teardown or retry could touch stale RX state. Set rx_pool, global_table, rxq, and alloc_page to NULL after free to mak…

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix reloc root cleanup in merge_reloc_roots() If the root we got has zero root refs in its root item, we are resetting the root's ->reloc_root without using barriers like we do everywhere else. Sashiko complained about this while reviewing another patch, and it's correct (see the Link tag below). Also, we should not clea…

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: validate sta_id in BA window status notif BA_WINDOW_STATUS_NOTIFICATION_ID extracts a 5-bit sta_id from the firmware notification and uses it to index fw_id_to_mac_id[] without bounds checking. Validate sta_id before array access to prevent out-of-bounds indexing.
