CVE-2026-41051: Vulnerability in SUSE openSUSE Tumbleweed
CVE-2026-41051 is a medium severity vulnerability in SUSE openSUSE Tumbleweed affecting the csync2 utility. The issue arises because csync2 uses insecure temporary directories when compiled with C99 or later, which allows time-of-check to time-of-use (TOCTOU) style attacks on these directories. This vulnerability has a CVSS 4. 0 base score of 5. 1, indicating a moderate risk. There is no information about affected versions or available patches. No known exploits are reported in the wild at this time.
AI Analysis
Technical Summary
The vulnerability CVE-2026-41051 affects the csync2 component in SUSE openSUSE Tumbleweed. When csync2 is compiled with C99 or later standards, it uses insecure temporary directories, which can be exploited via TOCTOU attacks. This means an attacker with local privileges could potentially manipulate temporary directories between the time they are checked and used, leading to possible unauthorized actions or data manipulation. The CVSS 4.0 vector indicates the attack requires local access with low privileges and user interaction, and it has a medium impact on availability. No official remediation or patch information is currently provided.
Potential Impact
The vulnerability allows local attackers with low privileges to perform TOCTOU attacks on temporary directories used by csync2, potentially leading to unauthorized file manipulation or disruption of service. The CVSS score of 5.1 reflects a medium severity impact, primarily affecting availability. There are no known exploits in the wild, and the impact is limited to local users with some level of interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should limit local access to trusted users and avoid running csync2 in environments where untrusted users have access. Monitor SUSE advisories for updates regarding patches or official mitigations.
