Technical Summary
This advisory covers two vulnerabilities in the python-tornado package for Red Hat Enterprise Linux 10. CVE-2026-31958 is a denial of service vulnerability that can be triggered by processing large multipart bodies. CVE-2026-35536 is a cookie attribute injection vulnerability resulting from improper handling of cookie arguments. Both issues have been fixed in updated python-tornado packages (version 6.5.5-1.el10_2). The advisory applies to Red Hat Enterprise Linux 10 across various architectures including x86_64, s390x, ppc64le, and aarch64. Red Hat rates the security impact as moderate and provides updated packages to remediate these vulnerabilities.
Potential Impact
Successful exploitation of CVE-2026-31958 could allow an attacker to cause a denial of service by sending large multipart bodies to the Tornado server, potentially disrupting service availability. CVE-2026-35536 could allow an attacker to inject cookie attributes due to improper handling of cookie arguments, which may affect cookie security and behavior. Both vulnerabilities have a moderate security impact according to Red Hat. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated python-tornado packages (version 6.5.5-1.el10_2) that address these vulnerabilities. Users of Red Hat Enterprise Linux 10 and its Extended Update Support versions should apply the available updates as described in the Red Hat advisory (RHSA-2026:19034) and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patches.
