CVE-2024-35793: debugfs: fix wait/cancellation handling during remove

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: 0.17% (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 3d08cca5fd0aabb62b7015067ab40913b33da906, 952c3fce297f12c7ff59380adb66b564e2bc9b64, e88b5ae01901c4a655a53158397746334778a57b.
Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 3d08cca5fd0aabb62b7015067ab40913b33da906, 952c3fce297f12c7ff59380adb66b564e2bc9b64, e88b5ae01901c4a655a53158397746334778a57b or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: debugfs: fix wait/cancellation handling during remove Ben Greear further reports deadlocks during concurrent debugfs remove while files are being accessed, even though the code in question now uses debugfs cancellations. Turns out that despite all the review on the locking, we missed completely that the logic is wrong: if the refcount hits zero we can finish (and need not wait for the completion), but if it doesn't we have to trigger all the cancellations. As written, we can _never_ get into the loop triggering the cancellations. Fix this, and explain it better while at it.
