CVE-2024-26807: spi: cadence-qspi: fix pointer reference in runtime PM hooks

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 03f1573c9587029730ca68503f5062105b122f61, 2c914aac9522f6e93822c18dff233d3e92399c81, 32ce3bb57b6b402de2aec1012511e7ac4e7449dc.
  • Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 03f1573c9587029730ca68503f5062105b122f61, 2c914aac9522f6e93822c18dff233d3e92399c81, 32ce3bb57b6b402de2aec1012511e7ac4e7449dc or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
