CVE-2026-97491: net/rds: Don't sleep inside rds_ib_conn_path_shutdown

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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).
  • Fixed version: Linux Linux 07a348d48e589b91a0d5a5cfa0de137cc703fabf, 16f48efaeb6991193fb7775c577f06f5b20b0c90, 934a6381c79d815680c955d676791322e020bfda; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1.

Low priority for now. Upgrade to Linux Linux 07a348d48e589b91a0d5a5cfa0de137cc703fabf, 16f48efaeb6991193fb7775c577f06f5b20b0c90, 934a6381c79d815680c955d676791322e020bfda; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net/rds: Don't sleep inside rds_ib_conn_path_shutdown New rds rdma self tests exposed a hang when tearing down the ib network configs. This is caused by the shutdown worker thread sleeping on the wait_event call, which blocks other work items in the queue. Fix this by changing wait_event to wait_event timeout, and looping until the wait check succeeds.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
