DescriptionCVE.org

UNIX symbolic link (symlink) following vulnerability in ilya-zlobintsev/LACT allows for local denial-of-service. This issue affects LACT: through 0.10.0.

AnalysisAI

Symlink following in LACT (Linux AMDGPU Control Tool) versions through 0.10.0 allows a local low-privileged user to redirect privileged file operations to attacker-chosen paths via a crafted UNIX symbolic link, resulting in local denial-of-service. Reported by SUSE and tracked in their Bugzilla (bsc#1276481), the flaw is rooted in CWE-61 and is confined to systems with multi-user local access where LACT is installed. …

Vulnerability AssessmentAI

Exploitation Exploitation requires local interactive access to a system where LACT is installed, with at minimum low-privilege shell access (confirmed by PR:L in the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H) scores 6.9, reflecting genuine local availability impact at low complexity and low privilege, though the local-only attack vector substantially limits real-world exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local low-privileged user identifies a file path that LACT's privileged process is scheduled to write to, then replaces that path with a symbolic link pointing to a sensitive system file or LACT's own runtime resource. When LACT executes its file operation, it follows the symlink to the attacker-chosen target, causing that resource to be corrupted, truncated, or locked - producing a denial-of-service condition. …
Remediation No independently confirmed patched release version is available in the provided data; the fix status should be verified directly via the upstream GitHub repository at https://github.com/ilya-zlobintsev/LACT and the SUSE Bugzilla report at https://bugzilla.suse.com/show_bug.cgi?id=1276481. … Detailed patch versions, workarounds, and compensating controls in full report.
