CVE-2026-63859

A flaw was found in the Linux kernel's airoha network driver. The airohaqdmacleanuptxqueue routine, responsible for cleaning up transmit queues, was missing critical steps. This omission could lead to improper resetting of Direct Memory Access DMA transmit descriptors and incorrect notification t...

CVE-2026-63973

In the Linux kernel, the following vulnerability has been resolved: net: mana: Add NULL guards in teardown path to prevent panic on attach failure When queue allocation fails partway through, the error cleanup frees and NULLs apc-txqp and apc-rxqs. Multiple teardown paths such as manaremove,...

CVE-2026-64175

CVE-2026-64175 concerns the Linux kernel’s iwlwifi/iwl_mld stack. When the Intel BE201 Wi‑Fi 7 firmware restarts after a crash, the TX path lacked a guard like the RX path, so iwl_mld_tx_from_txq() could dequeue and push frames to the transport layer while the firmware was dead. This caused iwl_t...

CVE-2026-63973

Concrete details found: Linux kernel net: mana module added NULL guards in teardown paths to prevent panics when attach fails. The fix protects against dereferencing apc->rxqs and apc->tx_qp after partial queue allocation failures. Affected functions and behavior: mana_chn_setxdp() now chec...

CVE-2026-63859 net: airoha: Add missing bits in airoha_qdma_cleanup_tx_queue()

In the Linux kernel, the following vulnerability has been resolved: net: airoha: Add missing bits in airohaqdmacleanuptxqueue Similar to airohaqdmacleanuprxqueue, reset DMA TX descriptors in airohaqdmacleanuptxqueue routine. Moreover, reset TXDMAIDX to TXCPUIDX to notify the NIC the QDMA TX ring ...

CVE-2026-63859

CVE-2026-63859 pertains to the Linux kernel driver for the airoha QDMA path. The fix adds missing steps in the airoha_qdma_cleanup_tx_queue() routine: it now resets DMA TX descriptors and sets TX_DMA_IDX to TX_CPU_IDX to signal that the QDMA TX ring is empty, mirroring the existing airoha_qdma_cl...

CVE-2026-53299

A flaw was found in the Linux kernel, specifically within the airoha network driver. This vulnerability arises from an issue where a variable ndesc is initialized too early in the airohaqdmainittxqueue routine. If a queue entry list allocation fails, this premature initialization can lead to a NU...
