CVE-2024-53685: ceph: give up on paths longer than PATH_MAX

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 0f2b2d9e881c90402dbe28f9ba831775b7992e1f, 550f7ca98ee028a606aa75705a7e77b1bd11720f, 99a37ab76a315c8307eb5b0dc095d8ad9d8efeaa.

Low priority for now. Upgrade to Linux Linux 0f2b2d9e881c90402dbe28f9ba831775b7992e1f, 550f7ca98ee028a606aa75705a7e77b1bd11720f, 99a37ab76a315c8307eb5b0dc095d8ad9d8efeaa or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ceph: give up on paths longer than PATH_MAX If the full path to be built by ceph_mdsc_build_path() happens to be longer than PATH_MAX, then this function will enter an endless (retry) loop, effectively blocking the whole task. Most of the machine becomes unusable, making this a very simple and effective DoS vulnerability. I cannot imagine why this retry was ever implemented, but it seems rather useless and harmful to me. Let's remove it and fail with ENAMETOOLONG instead.
