Leave strp_stop() unchanged so final cleanup still happens in\nstrp_done() after the work and timer have been synchronized.\n\n## Affected\n\n- `linux_kernel >= 4.9, < 5.10.258`\n- `linux_kernel >= 5.11, < 5.15.209`\n- `linux_kernel >= 5.16, < 6.1.175`\n- `linux_kernel >= 6.2, < 6.6.140`\n- `linux_kernel >= 6.7, < 6.12.86`\n- `linux_kernel >= 6.13, < 6.18.27`\n- `linux_kernel >= 6.19, < 7.0.4`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 7.0.4`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
