CVE-2023-53717: wifi: ath9k: Fix potential stack-out-of-bounds write in ath9k_wmi_rsp_callback()

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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 1af7eacfad45149c54893a8a9df9e92ef89f0a90, 554048a72d7ecfdd58cc1bfb56e0a1864e64e82c, 78b56b0a613a87b61290b95be497fdfe2fe58aa6.

Low priority for now. Upgrade to Linux Linux 1af7eacfad45149c54893a8a9df9e92ef89f0a90, 554048a72d7ecfdd58cc1bfb56e0a1864e64e82c, 78b56b0a613a87b61290b95be497fdfe2fe58aa6 or later.

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: Fix potential stack-out-of-bounds write in ath9k_wmi_rsp_callback() Fix a stack-out-of-bounds write that occurs in a WMI response callback function that is called after a timeout occurs in ath9k_wmi_cmd(). The callback writes to wmi->cmd_rsp_buf, a stack-allocated buffer that could no longer be valid when a timeout occurs. Set wmi->last_seq_id to 0 when a timeout occurred. Found by a modified version of syzkaller.

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.

No history yet (it accumulates with the daily EPSS job).

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.

Bug bounty scope

No known public program.
