Google Chrome: Use-after-free in Streaming component
Summary
A use-after-free vulnerability in the Streaming component of Google Chrome before 155.0.8059.39 could be abused by a remote attacker. The attacker would need social engineering to lure a user to a crafted HTML page. Successful exploitation could potentially execute arbitrary code inside the browser sandbox. Code execution is limited to the sandbox, so a separate sandbox escape would be needed for full system compromise.
Affected
- Google Chrome (desktop) before 155.0.8059.39 (per CVE description)
- Debian chromium package for bookworm before 155.0.8059.39-1~deb12u1 (distribution advisory)
- SUSE chromium for SLES 15.7 before 155.0.8059.39-bp157.2.241.1 (distribution advisory)
- Chromium-based browsers that ingest the fix are affected until they are updated. No fixed Microsoft Edge build is confirmed for this CVE.
Fixed in
- Google Chrome 155.0.8059.39 for Linux
- Google Chrome 155.0.8059.39/.40 for Windows and macOS (Google Chrome Releases, 6 October 2026)
- Debian chromium 155.0.8059.39-1~deb12u1 (bookworm)
- SUSE chromium 155.0.8059.39-bp157.2.241.1 (SLES 15.7)
Workaround
Unknown. The vendor fix is the mitigation. No vendor-documented workaround was found.
Exploitation
- Exploited in the wild: not known. CISA ADP Vulnrichment does not mark the CVE as known exploited; the CISA KEV catalog was not checked directly.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- Public proof of concept: none found.
Our recommendation
- Update Google Chrome to 155.0.8059.39 or later (Windows and macOS: 155.0.8059.39/.40 or later) via About Google Chrome or managed updates.
- Check the browser version across all workstations, not only the patch date, because staged rollouts can leave some machines behind.
- Update Chromium-based browsers and Linux distribution packages once fixes are available.
- Prioritise this update if users handle untrusted links, and install the full Chrome release, which also fixes other critical bugs.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
