RDMA/rxe: Fix "kernel NULL pointer dereference" error

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.95% (FIRST EPSS); higher than 60.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Linux Linux 0d773c58d702f0a7c16ee8d69617fd2c28350795, 3b8752f086eb6865cc3662ad13249b03024501e5, 48cd7098e71735ccafa0b3cf27c53924f9cb5b2f.

Low priority for now. Upgrade to Linux Linux 0d773c58d702f0a7c16ee8d69617fd2c28350795, 3b8752f086eb6865cc3662ad13249b03024501e5, 48cd7098e71735ccafa0b3cf27c53924f9cb5b2f or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix "kernel NULL pointer dereference" error When rxe_queue_init in the function rxe_qp_init_req fails, both qp->req.task.func and qp->req.task.arg are not initialized. Because of creation of qp fails, the function rxe_create_qp will call rxe_qp_do_cleanup to handle allocated resource. Before calling __rxe_do_task, both qp->req.task.func and qp->req.task.arg should be checked.

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+1% in 7 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.
