Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 455581

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: mvpp2: sync RX data at the
 hardware packet offset mvpp2 programs the RX queue packet offset, so hardware writes received data at
 dma_addr + MVPP2_SKB_HEADROOM. The current CPU sync starts at dma_addr and only covers rx_bytes +
 MVPP2_MH_SIZE bytes, which syncs the unused headroom and misses the same number of bytes at the packet
 tail. On non-coherent DMA systems this can leave the CPU reading stale cache contents for the end of the
 received frame. Use dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range offset so the
 sync covers the Marvell header and packet data actually written by hardware. (CVE-2026-53217)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
