How severe is CVE-2026-68352?

CVE-2026-68352 has a CVSS score of 8.3/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2026-68352?

CVE-2026-68352 affects the following packages: Kernel (Linux). Ecosystems affected: Linux.

How do I fix CVE-2026-68352?

Update Kernel to 6.6.148 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-68352 is resolved across your whole dependency graph.

How do I detect CVE-2026-68352 in my Linux dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Kernel. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-68352 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-68352?

O3 pinpoints whether CVE-2026-68352 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-68352 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-68352 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was CVE-2026-68352 published, and has it been updated?

CVE-2026-68352 was published on August 10, 2026 and was last updated on August 14, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Linux packages — download data is not available via public APIs for these ecosystems.

Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath6kl: fix OOB read from firmware IE lengths in connect event

The firmware-controlled beacon_ie_len, assoc_req_len, and assoc_resp_len fields in ath6kl_wmi_connect_event_rx() are not validated against the buffer length. Their sum (up to 765) can exceed the actual WMI event data, causing out-of-bounds reads during IE parsing and state corruption of wmi->is_wmm_enabled.

Add a check that the total IE length fits within the buffer.
