Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 460265

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix TSO DMA API usage
 causing oops Commit 66600fac7a98 ("net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB data")
 moved the assignment of tx_skbuff_dma[]'s members to be later in stmmac_tso_xmit(). The buf (dma cookie)
 and len stored in this structure are passed to dma_unmap_single() by stmmac_tx_clean(). The DMA API
 requires that the dma cookie passed to dma_unmap_single() is the same as the value returned from
 dma_map_single(). However, by moving the assignment later, this is not the case when priv->dma_cap.addr64
 > 32 as "des" is offset by proto_hdr_len. This causes problems such as: dwc-eth-dwmac 2490000.ethernet
 eth0: Tx DMA map failed and with DMA_API_DEBUG enabled: DMA-API: dwc-eth-dwmac 2490000.ethernet: device
 driver tries to +free DMA memory it has not allocated [device address=0x000000ffffcf65c0] [size=66 bytes]
 Fix this by maintaining "des" as the original DMA cookie, and use tso_des to pass the offset DMA cookie to
 stmmac_tso_allocator(). Full details of the crashes can be found at:
