AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Network exploitation is contingent on an application-specific code path exposing seekdir() to attacker input, making AC:H more accurate than the vendor-assigned AC:L; availability-only impact confirmed.

5DescriptionCVE.org
An issue in the seekdir() function (/dirent/mod.rs) of relibc commit 61f42d allows attackers to cause a Denial of Service (DoS) via a crafted input.
AnalysisAI
Denial of Service in relibc's seekdir() implementation at git commit 61f42d allows an attacker to crash or hang applications that use the library by supplying crafted directory position input to the vulnerable /dirent/mod.rs code path. The flaw is rooted in uncontrolled resource consumption (CWE-400), and a public proof-of-concept exploit exists at the Marsman1996 GitHub repository. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three simultaneous conditions: the target application must be compiled against relibc at or before commit 61f42d; the application must be network-accessible and must expose a code path that calls seekdir() in /dirent/mod.rs with attacker-influenced directory position data; and the runtime environment must use relibc as its C library (primarily Redox OS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.5 HIGH score (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) implies unauthenticated, low-complexity remote exploitation, which warrants independent scrutiny for a library-level vulnerability: relibc itself does not open sockets or accept network connections - exploitation depends entirely on whether a calling application exposes a code path through seekdir() to attacker-controlled input over a network interface, which is an application-specific condition the CVSS vector does not reflect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The upstream fix is documented in GitLab merge request #980 at https://gitlab.redox-os.org/redox-os/relibc/-/merge_requests/980. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and audit all applications and services consuming relibc library versions at or before git commit 61f42d, and implement immediate input validation on seekdir() operations to reject crafted directory position inputs. …
