Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 455130

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: spi: spi-fsl-lpspi: fix teardown order
 issue (UAF) There is a teardown order issue in the driver. The SPI controller is registered using
 devm_spi_register_controller(), which delays unregistration of the SPI controller until after the
 fsl_lpspi_remove() function returns. As the fsl_lpspi_remove() function synchronously tears down the DMA
 channels, a running SPI transfer triggers the following NULL pointer dereference due to use after free: |
 fsl_lpspi 42550000.spi: I/O Error in DMA RX | Unable to handle kernel NULL pointer dereference at virtual
 address 0000000000000000 [...] | Call trace: | fsl_lpspi_dma_transfer+0x260/0x340 [spi_fsl_lpspi] |
 fsl_lpspi_transfer_one+0x198/0x448 [spi_fsl_lpspi] | spi_transfer_one_message+0x49c/0x7c8 |
 __spi_pump_transfer_message+0x120/0x420 | __spi_sync+0x2c4/0x520 | spi_sync+0x34/0x60 |
 spidev_message+0x20c/0x378 [spidev] | spidev_ioctl+0x398/0x750 [spidev] [...] Switch from
 devm_spi_register_controller() to spi_register_controller() in fsl_lpspi_probe() and add the corresponding
 spi_unregister_controller() in fsl_lpspi_remove(). (CVE-2026-31485)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
