Echo: linux: security update to 6.1.140-1

medium Tenable Cloud Security Plugin ID 459575

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: Both cadence-quadspi
 ->runtime_suspend() and ->runtime_resume() implementations start with: struct cqspi_st *cqspi =
 dev_get_drvdata(dev); struct spi_controller *host = dev_get_drvdata(dev); This obviously cannot be
 correct, unless "struct cqspi_st" is the first member of " struct spi_controller", or the other way
 around, but it is not the case. "struct spi_controller" is allocated by devm_spi_alloc_host(), which
 allocates an extra amount of memory for private data, used to store "struct cqspi_st". The ->probe()
 function of the cadence-quadspi driver then sets the device drvdata to store the address of the "struct
 cqspi_st" structure. Therefore: struct cqspi_st *cqspi = dev_get_drvdata(dev); is correct, but: struct
 spi_controller *host = dev_get_drvdata(dev); is not, as it makes "host" point not to a "struct
 spi_controller" but to the same "struct cqspi_st" structure as above. This obviously leads to bad things
 (memory corruption, kernel crashes) directly during ->probe(), as ->probe() enables the device using PM
 runtime, leading the ->runtime_resume() hook being called, which in turns calls spi_controller_resume()
 with the wrong pointer. This has at least been reported [0] to cause a kernel crash, but the exact
 behavior will depend on the memory contents. [0]
 https://lore.kernel.org/all/20240226121803.5a7r5wkpbbowcxgx@dhruva/ This issue potentially affects all
 platforms that are currently using the cadence-quadspi driver. (CVE-2024-26807)

Solution

Update the linux library and its related packages to version 6.1.140-1 or later.
