CVE-2023-52929: nvmem: core: fix cleanup after dev_set_name()

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: 0.24% (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 23676ecd2eb377f7c24a6ff578b0f4c7135658b6, 39708bc8da7858de0bed9b3a88b3beb1d1e0b443, 560181d3ace61825f4ca9dd3481d6c0ee6709fa8.

Low priority for now. Upgrade to Linux Linux 23676ecd2eb377f7c24a6ff578b0f4c7135658b6, 39708bc8da7858de0bed9b3a88b3beb1d1e0b443, 560181d3ace61825f4ca9dd3481d6c0ee6709fa8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: nvmem: core: fix cleanup after dev_set_name() If dev_set_name() fails, we leak nvmem->wp_gpio as the cleanup does not put this. While a minimal fix for this would be to add the gpiod_put() call, we can do better if we split device_register(), and use the tested nvmem_release() cleanup code by initialising the device early, and putting the device. This results in a slightly larger fix, but results in clear code. Note: this patch depends on "nvmem: core: initialise nvmem->id early" and "nvmem: core: remove nvmem_config wp_gpio". [Srini: Fixed subject line and error code handing with wp_gpio while applying.]
